1. INTRODUCTION
As a pioneer specializing in the manufacture and supply of water, sewerage and high-quality industrial pipes, The Arabian Company for Water Pipes Industry Ltd. (ACWAPIPE) is focused on the future. Employing advanced techniques coupled with the production lines and global standards, ACWAPIPE contributes to the develpment of pivotal infrastructure projects. we also offer water services to government water authorities and municipalities, in addition to reaching out to the worlds industrial, agricultural and energy needs at local and international levels. Catering to the needs of high-profile projects, ACWAPIPE supplies premium pipes (chiefly the main lines for transporting and distribution of drinking water, sewerage and seawater, in addition to drainage of sewage and rainwater). We also play a leading role in industrial and chemical residues projects and desalination plants, cooling systems, fire fighting and irrigation systems. No matter how large or challenging a project is, we have the know-how and dedication to deliver viable solutions. Founded in 2007 as a limited liability company in the city of Riyadh, Kingdom of Saudi Arabia, ACWAPIPE is set to build a reputation for professionalism. Taking a comprehensive approach, we manage a number of industrial complexes for pipe manufacturing in the Kingdoms Eastern and Western Provinces, and we produce Glass Reinforced Plastic Pipes (GRP), Glass Reinforced Epoxy (GRE) and Reinforced Concrete Pipes (RCP). And to provide our esteemed clientele with even more, we are set to expand our manufacturing capabilities to encompass other types of pipes.
2. APPLICATIONS
GRP products are designed for use in normal to aggressive environments with wide temperature range. The following are standard applications for GRP products: Raw and potable water Sea and brine water Sanitary and industrial sewerage Oily sewer Chemical transport Fire fighting Cooling water
Consult the District Cooling for pipes intended to handle heavy industrial wastes; toxic chemicals, hazardous fluids or those for above ground or higher temperature services.
3. BENEFITS
ACWAPIPE manufactures Glass-Reinforced Polyester (GRP) Pipes and fittings using the Continuous Filament Winding (CFW) process. GRP products are superior to conventional piping materials due to the following basic features and benefit:
4. MATERIALS
GRP composite products derive strength and other properties from the raw materials used. The mechanical strength of pipe and fittings depend upon the type, amount and positioning of glass fibers, while the desired chemical, thermal and mechanical properties of the product is based upon the resin matrix used. GRP products use the best types and suitable size Tex of glass available in the market. For resins, we use polyester, epoxy and vinylester resins. Silica sand of the best quality is also used to provide stiffness to the mechanical pipe wall.
5. PRODUCTION PROCESS
ACWAPIPE, produces pipes and fittings using the continuous advancing mandrel method where glass filament reinforcements are wound continuously around a spiral steel band and aluminum beams called a mandrel. As the cylindrical mandrel rotates at designed speed, raw materials (resin, glass, silica sand ) are machine-fed on it to form the structural wall of the product. The pipe then proceeds into the oven zone for curing and is cut to proper size by automatic saw units. All settings and feeds are automatically executed and monitored by an advanced PLC program.
6. QUALITY ASSURANCE
Each individual pipe and sleeve undergo rigorous series of tests which include visual, hydraulic, stiffness, hoop tensile, axial tensile and other tests in accordance with ASTM, AWWA, ISO and other international material testing standards. The ACWAPIPE quality control department implements a strict screening process to ensure that only products passing the highest quality standards reach our clients.
GRP pipes are sized in accordance with international standards. The metric nominal sizes (DN) and thickness for different pressure and stiffness classes are tabulated in Appendix A.
8. JOINTS
Coupling/Bell-and-Spigot
Couplings are unrestrained joints capable of withstanding internal pressure but not longitudinal tensile loads. Joints with two grooves in the bell to retain elastomeric gaskets that will be the sole element to provide watethighness. To accomplish jointing requirements, GRP coupling are manufactured using the same GRP process. These couplings undergo same quality control test as that of pipes. Elastomeric rubber seals are employed to ensure water-tight joints even at near-transient pressures. Couplings allow certain angular deflection for pipe flexibility as shown below:
Allowable Angular Deflection per GRP Joint
Nominal Pipe Diameter, mm. < 500 > 500 to < 900 > 900 to < 1800 > 1800
DEFLECTION ANGLE
9. FITTINGS
To match the pipe specifications shown above, GRP fittings are also available in numerous types, and deflection angles and combinations to suit different field requirements. For detail dimension of standard fitting please refer to Appendix B. ACWAPIPE can produce fittings in all the sizes and different combinations based on the customer requirements. Some of the standard fittings are: Elbows- Different diameters and angles Tees Equal or Unequal Tees of different diameters Reducers Eccentric or Concentric of various diameters Flanges Flanges of various diameters drilled to International Standard as per requirements Other Fittings- End Caps, Puddle Flanges, Dummy Supports or combination of any of the above.

Raw materials are likewise tested before being used in the manufacturing of GRP products. These tests include viscosity, gel-time, styrene content, etc. for resin. Glass reinforcing fibers also undergo several tests. These tests ensure that the pipe materials comply with the specifications as stated.

14. INSTALLATION
Good performance and long life of GRP pipe can only be achieved by proper handling and installation of the pipe. It is important for the installation contractor, owners engineer and consultants to understand that GRP pipe is designed to utilize the bedding and pipe zone backfill support. The Contractor needs to understand that buried GRP pipes constitute a high-performance pipe-soil system which requires proper installation. When the properly compacted backfill provides the necessary structural support, the pipes unique properties can be harnessed to its full. For more details, refer to the Pipe Installation Manual. For GRP pipes installed either in very shallow trenches or in road sections with excessive traffic loads or both, specially designed concrete slabs maybe required over the pipe at road level to dissipate loads and avoid over-deflection. Consult the ACWAPIPE for specific installation instructions. In underground micro tunnel installations, the pipe sections to be inserted may require special accessories such as wooden or plastic sleds to protect the pipes and couplers from excessive sliding damage. Stoppers may also be needed to prevent pipes from over or under insertion into the sleeves. In Some instances grouting may be required before the section is hydro tested. Refer to the Installation Manual for details. Buried GRP pipes may indeed require some deliberate and careful attention to installation procedures. However, after proper installation is thoroughly done, the resulting pipeline is at once a flexible and a resilient fluid conveyor to last several years long continuous, maintenance-free operations and reliable performance.
