ON BEHALF OF Trenchless Australasia, I’m pleased to release this invaluable resource for the trenchless industry.

This year, the ASTT celebrates 10 years of publishing its official magazine, Trenchless Australasia. Through this decade, Trenchless Australasia has expanded into a range of leading installation and rehabilitation of infrastructure and assets. Our involvement in the trenchless industry spans our renowned magazine, trenchless e-newsletter and professional development events such as No-Dig Down Under and Trenchless Live.

Such offerings have allowed us to develop an established network of industry professionals, consisting of asset owners and managers, contractors, engineers and academics who inform us of the sector’s needs.

Our engaged audience continues to highlight for us where there are knowledge gaps in the trenchless industry, and it was through contact with us that we learned there was a lack of practical and unbiased information about the many and varied pipe types available in the Australasian market.

Due to this we decided to provide this free resource to help those working in the field of pipe installation and rehabilitation. This eguide covers: the benefits of different pipe products, which products are compatible for a range of trenchless installation and rehabilitation techniques, what questions to ask when buying pipe products, explanation of key terms and functions, information on new innovations, advice on how to future proof your asset, and a directory of suppliers.

The Complete Guide to Pipe Selection for Trenchless Projects will provide key decision makers with information to assist them in making the right decision when it comes to selecting pipe material in their upcoming projects.

I would like to thank valued supporters of this e-guide, without whom this free resource for the industry would not have been possible – Sponsors Australian Vinyls, Global Pipe, Iplex Pipelines and Qenos.

THERE ARE A number of pipe types currently available on the Australasian market, each with unique properties better suited to different installation and rehabilitation techniques. There is no one universal pipe material that is suited to all forms of Trenchless Technology. For example, microtunnelling requires a rigid pipe with sufficient compressive strength and ductility to be capable of withstanding massive jacking forces without fracture, whereas horizontal directional drilling (HDD) applications require a flexible pipe with high axial-tensile strength. Here, we look at some of the most common pipe types, their trenchless applications and industries/projects in which they are used.

POLYETHYLENE PIPEPE pipe is manufactured in Australia in sizes up to 2 m diameter (DN2,000). It

is lightweight and flexible with an allowable bending radius of 20-25 times the outside diameter of the pipe. This flexibility reduces the need for fittings and makes PE pipe excellent in shifting soils, or for installation over uneven terrain.

PE pipe can be supplied in straight lengths or in coils, reducing the need for joints and fittings, and can be jointed using butt and electrofusion techniques or using mechanical fittings. Butt welding involves the heating of two pipe ends to fusion temperature and then subsequently joining the two ends by the application of force. In trenchless applications, butt welding is used to create one large pipe string with a smooth outside surface. This results in one homogeneous pipe with effectively no weak spots, which is a major benefit of PE that is not apparent for other pipe materials.

PE pipe has been used extensively in trenchless installation for many years. Some of the earliest uses of large-diameter PE pipe in trenchless applications are in directional drilling for river crossings. PE pipe is suited for these installations because of its scratch tolerance and the fused joining system, which gives a zero-leak-rate joint with design tensile capacity equal to that of the pipe. To date, directional drillers have installed polyethylene pipe for gas, water, sewer mains, electrical conduits and a variety of other lines. These projects involved not only river crossings, but also highway crossings and right-of-ways through developed areas so as not to disturb streets, driveways, and business entrances.

Low density PE has high flexibility and retention of properties at low temperatures, however, is not generally suitable for trenchless applications. In HDPE, PE 80B has a minimum required strength (MRS) of 8.0 MPa as determined by regression analysis. In the past, this type of PE has been referred to as medium density PE or MDPE. The most suitable PE for trenchless applications is HDPE, specifically PE 100, which is the most recently developed polyethylene grade and has an MRS of 10.0 MPa. PE100 has higher strength, higher slow crack growth resistance and higher toughness than earlier generation materials, which has led to its use in many trenchless applications.

The PE100 pipe specification covers pipe designed for pressure applications. There are three categories of PE100 pipe: standard, high melt strength and high stress crack resistant (PE100 HSCR). Standard PE100 is suitable for all pressure application. In applications where very large-diameter or thick walled pipes are required, high melt strength PE100 offers a number of advantages around improved dimensional stability and increased throughput. In extremely aggressive installation conditions such as HDD through rock or a plough-in installation in rocky terrain, the extra protection of PE100 HSCR may be warranted.

PE pressure pipes are designated by their outside diameter or DN. For water and other general pressure applications, the maximum allowable operating pressure (MAOP) with a minimum service coefficient is designated by the pressure rating or PN. The standard dimension ratio (SDR) of a PE pipe is the ratio of the outside diameter and the minimum wall thickness. Pipes with a higher SDR have a thinner wall than pipes with a low SDR. The SDR can be related to the MAOP using the material MRS and the service coefficient appropriate for the application.

PVC PIPEPVC pipes offer many advantages for trenchless projects, including features

such as long lengths, corrosion resistance, lightweight and ease of installation with minimum disruption.

With major successes in large scale pipeline projects for below ground applications such as sliplining and pipe bursting, PVC pipes are suitable for a diverse range of trenchless construction projects and are particularly effective in the rehabilitation of existing sewers and watermains.

The benefits of PVC pipe for open-cut construction also makes PVC pipe a superior choice for trenchless installations in capital improvement projects as well as rehabilitation. PVC pipe is manufactured in sizes compatible with cast and ductile iron pipes, thus facilitating its connection to existing pipelines.

With thinner walls than alternative materials for virtually the same pressure rating and hydraulic capacity, trenchless PVC projects enable a smaller hole to be drilled, allowing less spoil to be removed, thus reducing disposal cost.

GRP PIPEWhen pipelines are laid in densely populated areas, protected natural habitats,

or beneath heavily frequented roads, jacking offers a minimally disruptive solution. Thanks to centrifugal casting, gravity as well as pressure pipes are manufactured with the compressive strength and wall thicknesses required to handle the jacking forces that are necessary to push the pipe and machinery.

GRP pipe features a smooth, non-absorbing exterior surface, tight outer-diameter tolerances and comparably light wall structure and is suitable for very long and also curved drives.

Apart from providing excellent hydraulic properties, the mirror-like smooth inner surface is easily maintained and disinfected, adding jacking to the installation portfolio of potable water lines where hygiene plays a major role.

The pipes’ small outside-to-inside diameter ratio provides an array of advantages. For instance, smaller jacking machines are required for the pipes, which means lower equipment and lease costs, less excavation material, and a larger pipe capacity.

Being light-weight, corrosion resistant, easily jointed due to push-together joints and rigid to resist grouting forces, GRP pipes and NC Line Systems are ideal for relining applications. A maximal mass flow is above all ensured thanks to the smooth inner surface (small roughness coefficient) and the relatively light wall structure of GRP pipes.

Applications - trenchless techniquesBEFORE SELECTING A pipe material, designers need to consider and establish the Trenchless Technology that will be utilised, taking in to account variables including the pipeline design life, hydraulic capacity, working pressure, project budget, application, alignment, locality, soil or rock type, depth, pit access, groundwater (fresh and saline), existing pipeline condition and possible hydrocarbon soil contamination.

Where microtunnelling is selected, designers will look for pipe materials with excellent compressive strength, ductility, hoop stiffness and toughness. If the soil is corrosive, then it will be advantageous to avoid ferrous reinforcement materials.

HDD calls for flexible pipe materials with good tensile and hoop strength to allow the pipe to be pulled into position through a curved borehole of the smallest practical diameter. This will minimise costs associated with spoil removal and drilling mud. Where the pipeline passes through brown-field sites, consideration should be given to the risk of hydrocarbon permeation.

Pipe bursting requires toughness and corrosion resistance to withstand damage to the pipe’s surface from shards of the original burst pipe along with good tensile strength to minimise the requirement for access pits. To maximise the internal bore of the rehabilitated pipe it is important to use a thin-walled pipe, so hoop strength will be a key consideration.

Sliplining also calls for a flexible thin-walled pipe with good ductility and toughness to maximise the rehabilitated pipe bore, whilst high axial (tensile) strength will contain project costs and disruption by reducing the need for access pits.

Non-structural lining calls for materials that suit the geometry of the host pipe being rehabilitated, so flexible materials with smooth, low-friction surfaces will ensure hydraulic conductivity is enhanced.

A brief history of pipeGRP PIPE

GRP PIPES WERE developed at the Basle Dye Works, Switzerland, in 1957, where wooden cylinders were employed for the dyeing process. These kept splintering and deforming after some time, putting the expensive textiles at risk. Seeking a suitable replacement for the cylinders, the factory’s engineers developed a centrifugal casting method using glassfibre reinforced plastics (GRP). Thanks to the method and material, they achieved perfectly concentric cylinders with a precise outer diameter and smooth surface - just as required.

GRP had previously been used in the shipbuilding, automobile and aircraft industries. However, its resistance to both corrosion and chemicals also made the material highly suitable for other applications. The Swiss recognised its benefits and soon employed centrifugally cast pipes for conveying water - the pipes laid at that time are still in use today. Step-by-step, the pipes have been improved, the manufacturing process has been automated, the product range extended and tailor-made fittings have been added during the subsequent years. A new company was born: HOBAS.

In 2009, the diameter range of HOBAS CC-GRP pipes was extended to 3,000 mm, and up to 3,600 mm in 2012.

In 2013, the first carbon-neutral HOBAS pipes were sold in Australia.

PVC PIPEPlastic pipe systems account for over 75 per cent of the pressure reticulation

pipelines being installed across Australia today and over 90 per cent of the sewer reticulation pipelines. PVC has long had a variety of options for trenchless installations, and recent developments in joining techniques have added to these options.

Manufacturing improvements have increased the size range available for PVC pipe. Technological advancements have made possible the option of butt fusing in the field, which has opened a number of trenchless application possibilities, particularly where long pull-in lengths are required. Other innovations have resulted in alternative joint designs suitable for sliplining, as well as directional drilling and pipe bursting.

SPONSORSPE PIPE

Polyethylene is a versatile thermoplastic polymer consisting of long hydrocarbon chains. It is made from ethylene, a gas that is usually derived from petroleum or natural gas, which in Australia is sourced from Bass Strait.

Polyethylene was first discovered in 1933 at ICI’s research laboratory at Winnington in England, as a result of experiments on ethylene gas at very high pressures. By chance, scientists Fawcett and Gibson, found a white waxy powder in the reactor and this proved to be a polymer of ethylene, today known as low density polythene or LDPE. In 1953, the use of low pressure polymerisation resulted in the development of HDPE and more recently, PE100 for pipe applications.

PE pipe manufacture commenced in Australia in the 1950s, with small-diameter pipes used for rural, irrigation and industrial applications. Since then, PE use and the number of applications for PE pipes has grown enormously, particularly in the areas of gas reticulation, coal seam gas, mining and trenchless applications.

Due to its ability to be welded in long continuous strings, polyethylene pipe has historically been the material of choice for HDD, pipe bursting and sliplining projects in Australia.

Modern HDPE pipe materials benefit from generational developments in the polymerisation process and exhibit superior resistance to crack development, increased hydrostatic pressure resistance and performance at elevated temperature. These developments have resulted in a far broader range of applications for HDPE pipe, including gas reticulation, water supply, mining slurries, irrigation, sewer and general industrial applications. The increase in performance in HDPE pipe grades has also led to the use of PE into applications traditionally serviced by concrete, steel and other polymers.

Pipe options: type, application, pricepointPVC

Recent innovations in pipe manufacturing have led to the availability of new products such as oriented PVC (PVC-O) and modified PVC (PVC-M) pressure pipes, and multi-layer light-weight non-pressure pipes and electrical conduit.

PVC-OPVC-O is made by realigning the PVC molecules through a process of biaxial

orientation. This greatly enhances the material properties - around twice the strength and ten times the impact resistance is achieved compared to traditional PVC-U material.

It means the wall thickness of PVC-O pipes can be reduced by up to 50 per cent while maintaining the same pressure as that of the traditional PVC pipe. The result is that PVC-O has a larger bore offering greater hydraulic capacity; the pipe is manufactured with significantly less embodied energy and is more material-efficient and cost effective compared to other pipe options.






SPONSORS

PVC-MPVC-M is an alloy of PVC, incorporating an impact modifier that improves the

fracture toughness and ductility of the material.This enhanced toughness enables PVC-M to be manufactured with a thinner

wall, with subsequent material savings and improved hydraulic properties. The alloying of PVC with modifying polymers achieves improvement in resistance to cracking. The result is the minimisation of the effect of stress concentrators such as scratches.

NON-PRESSURE PIPESDrain, waste and vent pipe as well as stormwater pipe and electrical conduit

are typically produced using a multilayer construction, through the use of modern manufacturing technology. This technology incorporates a foamed layer in the core of the pipe.

Modern manufacturing technology enables production of lighter weight pipes than the traditional solid wall pipes, reducing the weight of the pipe by up to 40 per cent. This produces a more material efficient pipe with significantly less embodied energy.

PVC PIPE MANUFACTURINGPVC pipe manufacturing is extremely efficient, with virtually 100 per cent of

the compound being used during the production of PVC and its conversion into finished products.

It takes four times less energy to make than concrete pipe, and half that used for iron pipe.

The benefits of choosing trenchless PVC technology for infrastructure projects include:

• Monolithic, fully restrained pipe system compatible with standard PVC, ductile and cast iron pipes and fittings

• Reduced installation cost owing to lighter weight and reduced pipe dimensions compared to alternatives

• Excellent abrasion and scratch resistant properties• Superior resistance to hydrocarbon permeation and chlorine based pipe

disinfectants• Continuous pull-in lengths exceeding 2 km have been achieved with fusible

PVC pipelines• Greater hydraulic capacity• Non-corroding• Lowest effect on water quality

PEPE pipe is made using the extrusion process. A PE pipe extrusion line consists

of a number of pieces of equipment. An extruder converts the polyethylene raw material to a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration device (which fixes its dimensions) to a cooling trough. After being cooled, the pipe passes via a haul-off to handling equipment for cutting into final lengths or coiling. Printing devices may also be inserted into the line to mark the extruded pipes with specific details.

The flexibility of PE pipe allows cost savings in installation. PE is often used in renovation of old pipelines as it can be readily inserted as a structural lining into an old pipeline. PE’s flexibility and resistance to ground instability means that PE gas and water systems were the only systems to survive the major earthquakes in Kobe, Japan in 1995.

PE pipe will outwear many more costly piping materials when conveying a variety of abrasive slurries in mining, dredging and similar applications. HDPE has excellent corrosion resistance and does not require cathodic protection. It is virtually inert and offers better overall resistance to corrosive acids, bases and salts than most piping materials.

Pipe systems made from HDPE have many benefits that contribute to lower life cycle costs. Pressure pipes made from PE100 resins are designed for a service life of 100 years. PE pipe does not rust, rot or corrode so costs are saved through a lower instance of repairs. It is leak tight with the heat-fused joints creating a homogenous, monolithic system with the joint strength equivalent to that of unjoined pipe. Polyethylene pipes and fittings are inherently tough and resistant to damage caused by external loads, vibrations and from pressure surges. Because polyethylene is smoother than steel, ductile iron or concrete, it has less drag and a lower tendency for turbulence at high flow and so a smaller PE pipe can carry an equivalent volumetric flow rate at the same pressure.

PE pipe systems readily achieve lower installation costs. Light-weight and longer lengths allow for significant savings in labour and equipment and fewer fittings are required due to the flexibility of the pipe. Reliable and permanent joining of pipe lengths through butt fusion techniques enable efficient and flexible installation in all applications.

A summary of benefits of PE pipe is listed below:• Does not corrode – inside or out• Welded system – no thrust blocks• Flexible pipe – resists ground movement• Shrink/swell soils• Earthquakes (PE gas mains in Kobe, San Francisco, Sichuan, Columbia,

Christchurch had much better survival rates than any other material)• Hydraulically smooth• Good surge resistance • Not affected by fatigue• Can use longer lengths and coils – less joints• Welded joints – reduced leakage• Can apply squeeze-off.

New TechnologiesCURVED PIPE JACKING

For economic and environmental reasons, curved pipe jacking is increasingly specified by designers and clients. Dividing the drive into straight sections with bends located inside the shafts necessitates the use of more numerous and, in many cases, deeper pits. With curved drives the quantity and the depth of these jacking pits can often be optimised.

HOBAS CC-GRP jacking pipes have unique benefits when it comes to curved

alignments. Their high compressive strength and elasticity are especially favorable features. Thanks to the elasticity of the GRP material, HOBAS jacking pipes react to eccentric loads by means of spigot deformation. The pipes therefore remain in full contact to each other without timber packing rings. This allows for an optimal transmission of jacking forces and higher steering precision.

PRESSURE JACKING PIPE SYSTEMSWhen pressure pipes are typically installed under a rail, roadway,

environmental site or densely populated urban area, the pipe is usually installed in an encasement pipe and then the annulus is grouted. This two pipe system is very costly not only because it requires the installation of two pipes, but also due to the larger diameter of the encasement pipe. With HOBAS pressure jacking pipes, no encasement is required. This provides the project with a substantial cost reduction.

PVC PIPEAlthough Fusible PVC™ is not as flexible as polyethylene pipe it offers pipeline

owners and trenchless contractors a number of real benefits in terms of acquisition and operating costs and asset performance.

a. Supplier Iplex employs specialist civil engineers to assist asset owners, designers and contractors with Fusible PVC™ product information, budget cost information and installation guidelines to ensure projects are thoroughly and professionally designed and costed to avoid unanticipated problems during project delivery and commissioning.

b. Fusible PVC™ is available in Series 2 pipe diameters, permitting the use of water industry standard fittings and valves. This eliminates the need for expensive electrofusion saddles and adaptors to valves, branches and mainline connections. Connections can be made safely and quickly without the need for specialised electrofusion equipment in the pit under all types of environmental conditions.

c. Since Fusible PVC™ is impervious to hydrocarbons and contains no rubber ring joints, it can be used confidently for the carriage of potable water through brownfields.

d. As Fusible PVC™ has a higher design stress than other polymer pipe materials it will invariably possess thinner walls. In many cases, permitting the use of a pipe one diameter size smaller than anticipated. This in turn reduces the amount of spoil to be removed and leads to substantial reductions in the amount of drilling mud used during construction, providing the contractor with lower construction costs.

e. Thinner walls result in lighter pipes. Light-weight Fusible PVC™ pipe strings allow the use of smaller directional drilling rigs or alternately, longer shots. In some instances, very long shots will be possible with Fusible PVC™ that would otherwise require intermediate access pits using other pipe materials.

f. The high modulus of Fusible PVC™ virtually eliminates elastic recoil during installation. There is no need to wait for the pipe string to relax before making connections, permitting projects to be completed in less time, saving cost.

Securing your pipe

g. Fusible PVC™ is manufactured in Australia by Iplex Pipelines under an exclusive technology agreement with Underground Solutions Inc. in the US. The licence agreement requires Iplex to supervise the welding and installation phases of construction to ensure UGSI’s high standards are maintained from design to commissioning. This provides the pipeline contractor with an onsite technical resource and the asset owner with the confidence that the pipe is being installed in accordance with the manufacturer’s recommendations.

h. Welding of Fusible PVC™ is only performed by licensed technicians who have successfully completed the intensive Fusible PVC™ training course provided by the technology owner, UGSI. This provides both contractor and pipeline asset owner with an assurance that the welding is being performed to the highest possible standards. Prior to pulling the pipe strings into position, all data logged weld parameters are reviewed and approved providing further assurance that the pipeline will provide reliable, fault-free service for the duration of its design life.

PE PIPE Once PE is chosen as the pipe material for your project, designing the

specifications of the PE pipe involves consideration not only of installation design factors, such as pull-back force limits and collapse resistance, but also of the long-term performance of the pipe once installed in the bore-hole. For specific projects, consult with a qualified engineer to evaluate the project and prepare a specification including design recommendations and pipe selection.

Pipe selection must take into account many aspects of the pipe performance through installation and end use. The designer will then make a recommendation of diameter (DN) and wall thickness (SDR). For example, in HDD the designer must recommend a PE100 material and a pipe specification suitable for the installation conditions (tensile stress during pull-back, external pressure, bending stress, torsion stress, etc) and the end-use performance requirements (pressure rating, flow rate, net external loads, etc). Pipe properties directly related to the material are used in calculating the required DN and SDR, therefore it is always best to work with a PE supplier that has the performance data available to design the most efficient pipe in terms of material usage.

A major advantage of PE pipe is that there is a local manufacturing industry ready to work with project owners. Along with Australia’s only manufacturer of PE pipe resin, Qenos, PE pipe extrusion is an Australian industry with sales revenue of hundreds of millions of dollars and manufacturing spread throughout the country. Australian PE pipe manufacturers are known globally for their innovation and quality. Local logistics, sales staff and customer service add to the value of your pipe installation project.

PE pipe supply lead times are much shorter than most other materials due to the local manufacturing industry. Manufacturing sites are located on the east coast from Tasmania to Townsville and in South Australia and Western Australia.

Future proofing your assetPVC: LONG LIFE AND DURABILITY

PVC pipe’s ultra-smooth surface reduces pumping costs and its leak-free joints eliminate water loss – which can be up to 40 per cent in some old-technology and corrosion-prone piping networks.

PVC pipe’s greatest environmental attribute is perhaps its exceptional durability and corrosion resistance - leading to better water conservation and lower replacement, maintenance and repair costs. PVC’s proven track record supports expectations of a very long service life. PVC has been used since the 1950s as both a water and sewer main material, longer than ductile iron and polyethylene. PVC pipes have a proven performance record of over 50 years in Australia, while overseas studies show the life expectancy of PVC pipes to be over 110 years.

Studies in the Netherlands have examined several potential degradation processes for PVC pipes and carried out tests on pipes up to 45 years old. These studies also concluded that the life of PVC drinking water systems could exceed 100 years.

PVC pipe is engineered and tested tough. It provides proven resistance to costly leakage. It offers unmatched corrosion resistance and reliability.

The longevity of PVC pipes means the pipes function more efficiently, reducing maintenance and ongoing work to the pipe, making it more affordable over time.

MAINTAINABILITY OF PVC PIPEDue to the high acceptance of PVC pipe for water and sewer applications, PVC

maintenance equipment, repair parts and appurtenances are readily available in the maintenance store or at the local distributor. There is no need to be concerned with having the proper materials for emergency repairs or routine connections. Many alternative products require stiffeners and other equipment that does not allow the utility to make a quality repair or connection with standard off-the-shelf fittings properly sized for the pipe. The outer diameters of PVC pipes are compatible with traditional iron pipes, allowing easier and faster connections when renovating pipe systems.

PVC’s coefficient of thermal expansion and contraction is up to four times less than that of alternative thermoplastic pipe materials, which minimises concerns over proper restraint. The higher modulus of PVC allows immediate connections to be made as it does not require relaxation time after installation, unlike polyethylene.






SPONSORS

RESISTANCE TO CORROSIONUnlike metal piping, PVC pipes won’t rust or corrode over time because it does

not react with air and water the way metal does, which results in a significantly longer lifetime of the pipe.

As PVC pipe won’t rust, scale, pit or corrode, it lasts longer and requires less maintenance than competitive materials, thus reducing repair and replacement costs and providing a lifetime of dependable service free of costly and damaging water leaks.

PVC is inherently well suited for buried applications as it does not corrode internally or externally. This eliminates the need to specify a corrosion protection method that adds costs and increases risks.

PVC is corrosion proof and not vulnerable to deterioration from low resistivity drilling muds commonly used with HDD and other trenchless construction methods. System design and installation are simplified with a homogeneous wall, and a durable pipe material that doesn’t require liners or coatings.

PE PIPEPolyethylene pipe systems can reasonably be expected to last 100 years or

more depending on the application. System life is dependent on many factors. If the design stress were used

in relation to the regression curve, predicted pipe life would be indefinite. As with other materials, the life is dependent on manufacture, transport, handling, installation, operation, protection from third party damage and other external factors.

For correctly manufactured and installed systems, the actual life cannot be predicted, but can logically be expected to be well in excess of 100 years before major rehabilitation is required. This may reduce depending on usage conditions for example, slurries and high temperatures.

For non-pressure pipes, the life of PE pipelines will be dependent on performance under four main conditions:

(a) Soil mechanics and pipe mechanics stability (b) Pipe material strength (c) Chemical and biological stability (d) Functional stability.
