Our Vision

To be the leader in the manufacturing, engineering & after sales services of GRP (FRP) piping and tank systems.

The above can only be achieved by our commitment toward the following:

• Fulfill the customer’s satisfaction and expectation• Ensure continuous improvement in all aspects.• Enhancing “Safety” as our first priority.

Recent Situation

The world’s infrastructure is aging. Millions of kilometers of water and sewer pipe need rehabilitation.

This dilemma is a worldwide problem. And where an aging infrastructure is not a problem, it’s generally because there are no infrastruture – it remains to be constructed in many developing countries. However, these nations, too, are faced with difficult decisions about how to build and what materials to use in order to avoid what happened in the developed countries.

Who’s the culprit? For the most part, corrosion is responsible for this problem.

• Internally unprotected concrete sewer pipes are rapidly deteriorated by the presence of sulfuric acid in a sanitary sewer system, which generated through the hydrogen sulfide cycle.

• Externally, soil conditions and stray electrical currents will deteriorate underground pipes. Poorly coated metallic pipes can corrode when placed in poorly aerated and poorly drained soils. The presence of sulphate-reducing bacteria will accelerate corrosion.

• These problems can be significantly reduced, if not eliminated, by the careful selection of materials resistant to corrosion protection, only to learn a few years later of the consequences. Where as corrosion is not a reversible process. The remedy to this situation is very simple. AMIANTIT fiberglass (FLOWTITE) brand of pipes.

AMIANTIT fiberglass is a glass-reinforced plastic (GRP) pipe produced on the continuously advancing mandrel process, ensuring a consistently uniform product meter to meter. Immune to galvanic and electrolytic corrosion, AMIANTIT fiberglass pipe is the ideal pipe choice for water supply systems. It’s proven resistance to the aci­dic environment found in a sanitary sewer speaks well for it’s use in waste water applications too. In fact, for more than 30 years now AMIANTIT fiberglass pipe has been the material of choice in many Middle East sewers, known to be the most aggressive in the world.

2 Why using AMITANK Fiberglass Water Storage Tanks

AMITANK potable water storage tanks from AFIL offer many benefits to its users. The water tanks are the result of a long lasting experience in developing and manu-facturing GRP products. Since decades, GRP tank products made by AFIL are successfully in use at many industries and applications.

AMITANK water storage tanks main features are:

• All products are certified by the Water Regulations Advisory scheme (WRAS)

• Less frequent maintenance

• No external painting for UV protection needed

• Non corrosive/non rotting

• Opaque walls and smooth inner surface avoid algae growth

• Persistent product due to multi-layer wall structure made of glass­fiber reinforced plastics

• Shipped to construction site pre-assembled and ready for installation

• Simple to repair

• Watertight, no infiltration, no exfiltration

All countries in the Middle East are facing very seri-ous water shortage. Therefore many governments have established water restrictions and the Govern-ments encourage people to only use a limited quanti-ty of water per day per person.

But water needs to be available in all homes in the right quantity for everyday`s use such as drinking, cooking, sanitary, laundry, showers, dishwashing or servicing a swimming pool. Water deliveries at home also need to meet peak demands for example in the morning when water is needed in bathrooms as well as in the kitchen at the same time.

A reliable basic water service is guaranteed by establi-shing water storage tanks. Storing water gives the free-dom to use water as much and whenever you want and the water tanks make independent from on-time delive-ries by public mains.

The AMITANK GRP water storage tanks can be establis-hed:

• aboveground • belowground

Aboveground installations are able on roofs or next to a building but in case of aesthetic concerns or a lack of space, the water can be also stored belowground what additionally keeps the water reasonably cool.

The main tank element of AMITANK is based on the manufacture of FLOWTITE GRP pipes that are produced and distributed as potable water pipelines all over the world since many decades. In this context, they have been tested and approved for the conveyance of potable water meeting many of the world’s leading authorities’ and testing institutes’ criteria. Among others, that inclu-des certificates from DVGW­Germany, Lyonnaise des Eaux-France or KIWA-Netherlands.

Therefore it is not astonishing, that all materials used for manufacturing AMITANK water tanks are made of raw materials are compliant to the regulations of NSF 61,

Ansi 61. NSF, the Nationals Sanitary Foundation is an internationally well renowned and leading organization that develops standards in regard of health safety and -protection.

All AMITANK potable water storage tanks are also certified by the Water Regulations Advisory Scheme (WRAS) than confirms

the suitability of the tanks for storage of potable water and the use of the stored water for human consumption.

More than 5,000 GRP water tanks have been already successfully delivered by AMIANTIT and its subsidiaries to customers in GCC and all over the world. The strict observation since more than 40 years has not shown any harmful effects on its users.

The production process itself undergoes a strict control. This includes in detail:

• Raw materials inspection – visual, chemical, operational

• Tank shell inspection – thickness, composition, hardness, strength

• End cap inspection – wall thickness, harnedd, visual appearance• Connections / Manholes – thickness, drillings, visual• Assembling process – dimensional inspection,

correct lamination inside, outside, leak testing, pipe marking, visual appearance

All AMITANK water tanks consist of a tank shell, end caps and different connectors and accessories. The basic raw materials used in manufacturing the tank are fiberglass, resin and filler. Usually unsaturated polyester resins are used since they give good performance for potable water applications.

The main body is manufactured using the continuous advancing mandrel process. This process allows the use of continuous glass fiber reinforcements in the circumfe-rential direction. For a pressure product or buried condu-it, the principle stress is in the circumferential direction. Incorporating continuous reinforcements in this direction therefore yields a higher performing product at a lower cost. A very compressed laminate is created that maxi-mizes the contribution from the three basic raw materials. Both continuous glass fiber rovings and choppable

roving are incorporated for high hoop strength and axial reinforcement. A sand fortifier placed near the neutral axis in the core is used to provide increased stiffness by adding extra thickness.

The tank shell will be equipped with all requested con-nectors and accessories before the end caps will be added to the main body by using the lamination method. To test the proper manufacturing and tightness, an air pressure- and vacuum text is carried out at the factory for each tank before dispatch.

The continuous winding process allows the manufacture of AMITANK potable water tanks with individual diameter and volume, based on customer’s request. However, we also offer a standard product range of AMITANK pota-ble water tanks that can be installed above and below-ground.

6 Product Range 7 Installation

The installation of AMITANK water storage tanks is pos-sible below-ground and above-ground.

Belowground:• To ensure proper construction and employee safety,

tank trenches have a typical value of “0.4 A* DN” • The tank bedding should be placed over a firm, sta-

ble trench bottom to provide proper support. All the tanks are designed to withstand internal pressure of water column and also they are designed to take a cover depth of 1500 mm based on Saudi Arabian soil conditions.

• It is very important that the backfilling and compac-tion are done in the right way. The used material in the area between the bedding and the underside of the tank should be worked in and compacted.

• In some cases, the tank must be restrained against movement. This is usually done by strapping over the pipe to a base slab or other anchors

A complete belowground installation manual is provided separately for the proper installation.

Aboveground: AMITANK water storage tanks can be also installed above ground. The tanks can be laid and fixed on sepa-rately available supports. Due to the low thermal coeffi-cient of GRP in regard of linear expansion, the tempera-ture difference, between supports and tank is of no great concern. For more details please request the separately available aboveground installation manual.
