Introduction
The self-anchoring or locking of socket joints is an alternative technique to using concrete anchor blocks to absorb hydraulic thrust forces. These forces are generated by changes in direction, cross section or branch off-takes on water supply and distribution pipes.
Self-anchoring is an especially attractive option when there are restrictions on the size of fittings, notably in urban areas, and in unstable ground or when it is difficult to obtain sufficient quantities of concrete.This technology does away with heavy, space-consuming concrete anchor blocks. Self-anchoring also has the advantage of being time-saving when assembling pipe components and allows pipelines to be tested immediately after being laid as there is no need to wait for concrete to set.
has developed a complete range of self-anchoring solutions suitable for all operating conditions and installation configurations
.
The wide range includes the following self-anchoring techniques:
• STANDARD Vi in the range from DN 60 to 300
• EXPRESS Vi in the range from de DN 60 to 300
• STANDARD Ve in the range from DN 80 to 1200
• PAMLOCK in the range from DN 1400 to 1800
The range has now been further enhanced with many new technological innovations recently implemented by :
• STANDARD Vi in the range from DN 350 to 600
• UNIVERSAL Vi and Ve in the Natural range from DN 80 to 600
• UNIVERSAL Ve in the classic range from DN 700 to 1200
Using self-anchoring systems is the modern way of installing ductile iron pipelines while making the most of their outstanding mechanical properties.
's goal is to make its self-anchoring solutions easier to understand, specify and install.

Self-anchoring water pipes, Why?
Hydraulic thrust forces occur at the location of changes in direction, reductions in diameter (bends, tees, tapered sections) and at the end of pipelines carrying pressurized fluid. These forces may lead to joint separation on the pipeline unless they are counteracted by using concrete anchor blocks or self-anchoring devices.
Standards EN 805 and EN 545 define three pressures to specify the characteristics of water pipeline.
PFA – Allowable working pressure
Maximum hydrostatic pressure that a component is capable of withstanding continuously in service.
PMA – Maximum allowable working pressure
Maximum pressure occurring from time to time, including surge, that a component is capable of withstanding in service.
PEA – Allowable test pressure
Maximum hydrostatic pressure that a newly installed component is capable of withstanding for a relatively short duration, in order to ensure the integrity and tightness of the pipeline.

Hydraulic thrust forces can be very severe and must be counteracted by suitable self-anchoring devices or concrete anchor blocks.
Hydraulic thrust forces can be calculated using the following general formula:
F = K.P.SF : thrust force (in N)P : maximum internal pressure
(on-site test pressure) (in Pa)S : cross sectional area
(inside for flanged joints, outside for all other types) (in m2)
K : coefficient according to the geometry of the piping component concerned

Greater freedomin designing networks
Phasing out concrete anchor blocks
Self-anchoring technologies are increasingly taking the place of concrete anchor blocks which have many drawbacks including their weight and size.
• Space on work sitesThe larger the diameter of the pipeline, the bigger the anchor blocks required. This can lead to real problems as the limited space available under ground has to be shared by a great many networks (such as gas, sewage, telecommunications and cable networks).
• Trench opening timeGood concreting practices require a maturing time of 28 days before applying a load. Even if this time can be shortened, it constitutes a major constraint that is no longer acceptable in urban areas.
• Long-term risks of destabilizationThese risks may be due to natural causes, such as non-homogeneous soils or irregular ground, nearby digging for work on other networks, especially in urban areas. These factors affect the stability and, therefore, the durability of concrete structures and raise the fear of possible junction separations.
• A heritage that is hard to manageMajor dismantling works have to be carried out when modifications or servicing are required on a pipeline or, later on, when a pipe has to be removed at the end of its life.
Self-anchoring: A modern approach to water supply networks
The utilization of self-anchoring solutions is growing fast in most countries all over world. These solutions offer significant advantages:
• Limiting space requirement undergroundPipelines fitted with self-anchoring systems take up no more space than pipelines without self-anchoring. This leaves space for other networks and, what is more, helps reduce the volumes of material to be excavated.
• Reducing logistic constraintsFor reasons such as accessibility and cost, it is not always easy to bring in several cubic metres of concrete to make anchor blocks. Pipeline laying rates are often limited by the rotation of trucks delivering concrete. Self-anchoring devices are light and easy to transport to the installation site, whether it be in the city, in the country, or in remote mountainous or desert regions.
• Quick installation and setting into serviceSelf-anchoring systems are extremely quick to install, especially the STANDARD Vi and EXPRESS Vi systems. What is more, they can be submitted to hydraulic tests immediately after being installed.
• Proven stability and durabilityThe operation of self-anchoring systems relies on a combination of their intrinsic resistance to joint separation and friction with the soil. 's recommendations on self-anchoring lengths take into account the type of soil and the risks of works conducted in the vicinity of the pipes. The self-anchoring systems receive the same level of corrosion protection as the pipes and fittings.
• Possibility of dismantlingPipelines can always be dismantled with tools supplied by , without entailing long and extensive civil engineering work.

Greater flexibility for network acceptance procedures
Pipe laying and site acceptance procedures have been speeded up and have reached an unprecedented level of reliability thanks to self-anchoring devices.
• No longer any need to wait for concrete to setPipes are ready for pressure testing as soon as the anchoring devices have been fitted.
• Doing away with test anchor blocksThere is no longer any need to make test anchor blocks for the individual testing of pipeline segments thanks to the use of EXPRESS Vi flanged socket fittings.
• Shorter segments can be testedIt is now possible to test shorter lengths of pipeline so it is easier to locate and solve any problems that may arise and trenches can be refilled more quickly.
Saint-Gobain self-anchoring devices can be tested up to their allowable test pressure (PEA) during acceptance tests. (See pages 21, 23, 24, 28).
Self-anchoring solutions to meet increasingly strict pipe-laying requirements
The various self-anchoring solutions can be adapted to respond to even the most difficult pipe-laying situations:
• Casing pipe-laying, road crossing, tunnels, bridges,
• Directional drilling or pipe bursting replacement (UNIVERSAL Ve, see directional drilling brochure, DIREXIONAL),
• Laying in mountainous areas, notably using UNIVERSAL self-anchoring solutions adopted in the ALPINAL range (see the ALPINAL brochure), and also for micro hydroelectric power plants, etc.
• Pipe-laying in poor soil or submerged ground, etc.

- Save on materials: joints weighing just a few kilos can replace several tons of concrete.
- Save space: thanks to the compactness of these systems.
- Save on transport (for earth fills and concrete).
- Save time.
- Save wood, as formwork for concrete anchor blocks is no longer needed.

A variety of self-anchoringtechniques
The self-anchoring of ductile iron pipelines can be achieved using two technical solutions
• Insert type self-anchoring techniquesWith insert type self-anchoring systems, joint separation is prevented by means of hard stainless steel inserts which fit into sockets in the pipes or fittings. These inserts have teeth which grip the spigot end of the pipe or fitting and lock it against axial displacement. These insert systems rely on the ductile nature of the cast iron which allows the penetration of inserts without any risk of failure.
The main advantage of these systems is that they can be implemented on site without any special preparation.
The inserts can be fitted in the sealing chamber, as in the case of self-anchoring devices of the STANDARD Vi type, or in a specially designed self-anchoring chamber, as in the case of the UNIVERSAL Vi self-anchoring system.
• Bead type self-anchoring techniques With bead type self-anchoring systems, joint separation is prevented by pressing a metal locking ring, which fits into socket in the pipe or into the mating flange installed before the socket, onto a metal bead on the spigot end. This bead is made by welding (in the case of pipes) or by casting during manufacture (which is generally the case for fittings).The main advantage of these self-anchoring systems is their ability to withstand very high pressure.
With bead type devices, the self-anchoring mechanism is always located in a specially dedicated chamber.

Self-anchoring solutionsthat are fully tried and tested
self-anchoring systems are designed and tested in strict compliance with the quality assurance procedures specified by Standard ISO 9001-2008 and in keeping with the Standards applicable to ductile iron pipelines including, in particular, Standards EN 545 and ISO 10804-1, as well as 's specific internal specifications.
Test Conditions Pressure Purpose
Positive internal pressure Maximum deflectionShearing force 50 DN 1,5 PFA+5 bar To check joint's ability to withstand
the hydraulic thrust
Negative internal pressure Maximum deflectionShearing force 50 DN -0,9 bar To check joint's air tightness
Cyclic internal pressure Shearing force 50 DN24000 cycles
PMA-5 ->PMATo check joint's fatigue behaviour
Positive external pressure Maximum deflectionShearing force 50 DN 2 bar To check joint's resistance to
penetration of groundwater
Thanks to this strict approach, is able to provide its customers with self-anchoring solutions of outstanding reliability.The self-anchoring devices are submitted, specifically, to four essential tests prescribed by European Standard EN 545.
These tests are conducted in a COFRAC (EN 17025) approved laboratory and various combinations of mechanical conditions are applied in order to reproduce all the installation conditions (not only average conditions).
For the design of new products, PAM goes further than the requirements specified in applicable Standards:
• Each diameter (DN) is individually tested (rather than just one diameter for each product range).
• The durability of joints is assessed by internal pressure testing at 80°C for six monthss.

Our self-anchoring solutions:a complete range to meet your needs
Solutions for most common situations
Our solutions are based on the following self-anchoring techniques:
• STANDARD Vi for pipes, DN 60 to 600 and for fittings DN 350 to 600.
• EXPRESS Vi for fittings, DN 60 to 300.
The performance of these self-anchoring systems is suitable for the usual water distribution and supply requirements.
Solutions for high pressures and high hydraulic thrusts
Our solutions are based on the following self-anchoring techniques :
• UNIVERSAL Vi for pipes and fittings, DN 80 to 600 .
• UNIVERSAL Ve for pipes and fittings, DN 100 to 1200 .
• PAMLOCK for pipes and fittings, DN 1400 to 1800.
UNIVERSAL Vi offers the same simple fitting as the STANDARD Vi range but uses special double-chamber fittings and pipes. This very practical solution caters for pressures higher than those withstood by STANDARD Vi.
UNIVERSAL Ve is designed for use at very high pressures or large diameters from DN 700 to 1200 where massive hydraulic thrusts occur.
PAMLOCK is an extension of the UNIVERSAL Ve range for very large diameters from DN 1400 to 1800.
Supplementary solutions
Our supplementary solutions are based on the following self-anchoring techniques:
• STANDARD Ve for pipes and fittings, DN 80 to 1200.
• STANDARD V+i for fittings, DN 350 to 600.
With the STANDARD Ve self-anchoring system, which provides performance close to those of the UNIVERSAL Ve range, the decision to anchor high-pressure pipelines can be taken on site. Pipes or fittings with STANDARD single-chamber joints can be installed by means of counter flanges or by adding a weld bead.
The STANDARD Ve and STANDARD V+i self-anchoring devices can also be used with UNIVERSAL Ve and Vi pipes, particularly at diameters of DN 350 and 450, for which no UNIVERSAL fittings are currently available..
's self-anchoring solutions are designed according of two different levels of performance, plus a supplementary range to cater for some specific situations

What length of pipeline should be anchored?
The technique is based on the principle of anchoring joints over a sufficient length on both sides of a region of hydraulic thrust, such as a bend, in order to harness soil/pipe friction forces to counteract the thrust force.
The calculation of the length to be anchored does not depend on the self-anchoring system used. It depends on the test pressure, the pipe diameter and the parameters shown in the two figures, C & D.
The following formula is used to calculate the self-anchoring length L:

Parameters required
to calculate self-anchoring
length- Wp : weight per metre of empty pipe (in N/m)
- Ww : weight per metre of water (in N/m)
- K : coefficient of earth fill pressure distribution around pipes (depending on compacting, K = 1,1 to 1,5)
- ƒ : coefficient of soil/pipe friction- We : weight per metre of earth fill (in N/m)
- α1 = 1, for test with joints with earth fill
- α1 = 2/3, for test with uncovered joints- D : pipe outside diameter (in m)
- H : covering height (in m)
- α2 = 1 ; pipe with zinc or zinc-aluminium coating + bituminous or epoxy paint
- α2 = 2/3 ; TT pipe, with polyethylene or polyurethane coating
- α2 = 2/3 ; pipe with polyethylene sleeve where Kf = min (K.2/3.tg (o,8φ); 0,3)

A safety coefficient may be applied to the length to be anchored, depending on:- the laying conditions, - the quality and compaction of the earth fill,- uncertainty regarding the physical characteristics
of the earth fill.
In case of ground with an average mechanical resistance, consisting of gravel or silty sand, with an internal friction angle of 30°, for a zinc or zinc-aluminium coated pipe with sealer and a safety coefficient of 1.2 and a test pressure of 10 bar, the lengths to be anchored are indicated in the table above.
Where applicable, allowance should be made for any partial presence of groundwater by correcting the weight of the full pipe by applying the corresponding buoyancy value.

Easier installation by skilled personnel
Cutting down on long tedious operations
To encourage development of the use of self-anchoring techniques, set out to make them easier to install by cutting down on tedious, time-consuming operations. This approach is illustrated by its insert type self-anchoring devices (STANDARD Vi, EXPRESS Vi and UNIVERSAL Vi) and double-chamber self-anchoring devices.
Insert type self-anchoring• Devices of this type are obtained by fitting
insert rings in specially designed sockets.• There is no need to make new weld beads if
pipes are cut.• Thanks to the performance of Vi self-anchoring
devices, there is no need to use Ve weld bead type self-anchoring systems in the NATURAL range DN 60 to 600, other than in exceptional cases.
UNIVERSAL self-anchoring• There is no need to fit mating flanges or to
tighten bolts.• UNIVERSAL pipes and fittings are compatible
with versions Vi and Ve (provided there is a weld bead on spigot ends).
Operations performed by professionals
Owing to the extreme hydraulic thrusts they have to withstand, self-anchored junctions are vital for network safety. Special care must be taken when installing self-anchoring devices and this operation must therefore be carried out by properly trained personnel. For this reason, provides the following services:
On-site technical sales assistanceTeams of engineers and technicians with expertise in ductile iron pipelines are at your service for start-up operations on site. They can also help you choose suitable self-anchoring methods and the pipe lengths to be anchored (with the help of computational software).
Installation adviceAn installation data sheet is supplied with each self-anchoring device, in the packaging containing its various components. can also supply a set of installation advice leaflets giving practical details of the operations to be performed.
Customer training school organizes training sessions on the
implementation of self-anchoring systems through its customer training school.
Understanding the different service conditions
For buried water distribution and supply networks, the choice of self-anchoring system to be used depends on the network's working pressure and on the test pressure applied during the site acceptance procedure.
For other cases, the mechanical operating principles at junctions should be taken into account as well as pressure levels. The following guidelines must be complied with:
• Insert type self-anchoring devices are not suitable for installation by pulling. If pipe lengths are to be pulled, bead type self-anchoring should be used.
• A specific study of the support of pipelines must be conducted, notably allowing for network operating conditions (pressure, hydraulic service conditions, etc.), support techniques, support bearing points, axial load pickup points and any other relevant data.
• In the specific case of bridges, the pipeline must be uncoupled from the structure when it has been self-anchored. (The bridge and the pipeline must be free to expand and contract independently to avoid generating supplementary stresses).
• See the table on the next page for further details

Implementing good practices
Some basic professional rules must be complied with when installing self-anchoring systems:
• Work in a professional mannerBefore fitting self-anchoring devices, you should make sure that all gaskets, locking ring, locking clips, sockets and spigot ends on all components are clean and free of foreign bodies.Chamfers on spigot ends must comply with the applicable general specifications to ensure optimal fitting.Weld beads must be visually checked for any damage sustained during handling and transport.
• Assemble in aligned position, then apply any deflectionFriction surfaces (especially spigot end and inside face of joint) must be lubricated with
lubricant paste. Gaskets are to be fitted aligned with the socket centreline. Deflections are applied afterwards. Whatever deflection is required, avoid fitting the spigot end fully home in the socket and comply with the fitting depth markings painted on the spigot end.
• Do not re-use locking rings or locking clipsWhen anchored joints are dismantled, whether they were pressurized or not, the locking rings or locking clips should not be re-used in another joint.
• Use fitting accessories Use only accessories supplied by for the fitting of UNIVERSAL Ve, PAMLOCK and STANDARD Ve locking devices.
• Lock the UNIVERSAL Ve and STANDARD Ve self-anchoring devicesAfter fitting the self-anchored UNIVERSAL Ve and STANDARD Ve joints, they should be locked by the appropriate means.
• Comply with bolt tightening instructionsFor systems with counter flanges and bolts, the bolt tightening instructions specified in installation advice sheets and leaflets must be complied with.
• Use pipes and fittings self-anchoring systems are carefully
designed to ensure reliable, optimal operation with pipes and fittings. The operational design specifications used in the construction of these self-anchoring devices (design of sealing chambers and locking chambers, etc.) are not covered by European tandards. UNIVERSAL and PAMLOCK pipes have wall thickness was higher than the values of pressure classes specified in EN 545 and ISO 2531 to increase the anchoring performance. declines any liability if parts of different origins are used.

Self-anchoring devices for the rangePerformance details
• Angular deflectionEnsure compliance with the maximum angular deflection specified in the table, and note the angular deflection of self-anchored joints is generally slightly less than that of joints that are not self-anchored.
• FittingsUNIVERSAL fittings are not available in DN 350 and 450. STANDARD V+i self anchoring fittings should be used with UNIVERSAL Vi pipes, and STANDARD Ve fittings should be used with UNIVERSAL Ve pipes in these 2 DN. (See p 24).
• Combined use of NATURAL STANDARD and NATURAL UNIVERSAL pipesWhen performing cutting operations on site, be sure to distinguish cuts performed on UNIVERSAL pipes from cuts made on STANDARD pipes (by applying paint to mark cuts on UNIVERSAL pipes, for example). Only UNIVERSAL cut sections can be fitted in UNIVERSAL sockets with the self-anchoring pressure levels specified in the table.
• Higher pressureFor pressures higher than those specified in the table, please consult us.
• NATURAL PURSee page 28 for self-anchoring solutions for the NATURAL PUR range.

For diameters greater than DN 300, one solution for pipe-laying firms is to ballast pipes in order to reduce tensile loads..
“These recommandations are based on the experience gained by Saint-Gobain . The pipe-laying company has sole responsibility for the installation of products in accordance with the rules of art”.
See our brochure, ‘there are places where discretion is paramount’, for more information on 's product range for directional drilling

Directional drilling, an innovative technology to reduce disturbances
Buried networks have greatly increased in number and their characteristics have progressed along with economic development, technological progress and demographic growth.
Trenchless pipe-laying techniques, especially directional drilling and in-line pipe replacement provide an effective, targeted response when the impacts of pipe-laying works have to be limited

Pipes equipped with UNIVERSAL Ve joints and special external coatings of the STANDARD TT (PE and PUX) type are ideally suited to directional drilling and in-line replacement.
The outstanding mechanical strength of UNIVERSAL Ve joints and their great ability to withstand angular deflection allow the pulling of pipe lengths of several hundred metres without any risk of joint separation. (See the table below).

ISOPAM
ISOPAM pre-insulated pipelines are designed to provide heat insulation for networks that are especially exposed to risks of freezing. They consist of ductile iron pipes with heat insulation fitted in the factory. Their mechanical and leak-tightness properties are identical to those of standard ductile iron pipes.
Pipelines can sometimes be subjected to the risks of freezing. When required by current conditions (low flow rate, unfavourable weather conditions, installation above ground), pipelines have to be insulated to minimize heat exchanges with the outside environment. offers a factory pre-insulated pipe system to cater for that need.

The angular deflections of ISOPAM pipelines are different from those of non-insulated pipelines owing to the geometric constraints imposed by insulating their joints.
NATURAL PUR ductile iron pipes with polyurethane internal coating, as per Standard EN 15655, and corresponding fittings are to be used for the transportation of water of the following types only:
• Very soft water (hardness less that 5°, french degree), combined with long dwell times (more than 3 days) when a standard cement mortar coating is unsuitable (risk of increasing the water's alkalinity).
• Mineral water, i.e. water whose chemical specifications must remain unchanged between the pipeline inlet and outlet.
The utilization of insert type self-anchoring systems such as STANDARD Vi, EXPRESS Vi or UNIVERSAL Vi is not recommended for the transport of water with these characteristics. Please consult us.
recommends the use of bead type self-anchoring solutions:
• For DN 100 to 600, a NATURAL UNIVERSAL Ve PUR offering is available for UNIVERSAL pipes with bead type self-anchoring. The performance is the same as that for UNIVERSAL self-anchoring on pipes with internal coatings of blast furnace cement mortar (see page 24).

• In the range DN 700 to 1800, the classic PUR range is available and UNIVERSAL Ve, PAMLOCK and STANDARD Ve self-anchoring solutions can be used.
The internal coating should be repaired if pipes are cut or weld beads are made on the work site.
