Water Transmission

GRP pipes are widely used for potable and irrigation water transmission due to their lightweight design, corrosion resistance, and long service life. They ensure safe, efficient, and cost-effective delivery of clean water across long distances.

Energy Plants

In power generation and cooling systems, GRP pipes offer excellent thermal resistance, durability, and low maintenance needs. They are ideal for circulating water in cooling towers and handling demanding plant environments.

Sewer & Drainage Systems

Thanks to their smooth internal surface and chemical resistance, GRP pipes provide reliable performance in sewer lines, stormwater drainage, and wastewater systems. They minimize leakage, scaling, and long-term operational costs.

Chemical & Petrochemical

GRP pipes are engineered to withstand corrosive chemicals, high pressures, and aggressive fluids. This makes them a trusted choice for transporting petrochemical products, acids, and industrial effluents safely and efficiently.

GRP Pipe Types

How to choose the best pipe?

GRP vs GRVE vs GRE — Quick Comparison

Comparison of material, pressure rating, applications and other technical attributes for GRP, GRVE and GRE pipes.
Feature GRP GRVE GRE
Material Glass-fibre reinforced polyester resin. Glass-fibre reinforced vinylester resin for better chemical resistance. Glass-fibre reinforced epoxy resin — high-performance thermoset.
Pressure Rating Good for municipal & industrial applications. Higher pressure than GRP at same thickness. Excellent high-pressure and cyclic loading resistance.
Temperature Resistance Moderate service temperatures. Better than GRP for warmer process fluids. Highest temperature resistance of the three.
Chemical Resistance Good for sewage and water; depends on resin type. Enhanced resistance to aggressive chemicals. Excellent with epoxy; best for harsh chemicals.
Applications Water, sewer, desalination, general piping. Chemical plants, coastal & corrosive areas. High-performance & petrochemical pipelines.
Durability Long life, low maintenance. Extended lifecycle in harsh environments. Very long life in demanding conditions.
Cost / Value Most cost-effective. Higher than GRP but longer-lasting. Highest cost, justified in critical projects.

Technical Insights for Engineers and Project Managers

To help you go deeper into the technical aspects of GRP piping, we’ve prepared dedicated guides on key topics:

1-Diameter

Faratec pipes can be supplied in the following nominal diameters (mm). Smaller and other diameters are available on request. Please contact Farassan Company for more information
Continuous Filament Winding:

300 350 400 450 500 600
700 800 900 1000 1100 1200
1400 1600 1800 2000 2200 2400
2600 2800 3000 3200 3400 3600
3800 4000

Discontinuous Filament Winding:

25 50 100 150 200 250 300

2-Length

The standard length of  Faratec pipes for diameters over 300 mm is 12 meters, for diameters 100 to 300 mm is 6 meters and for diameters less than 100 mm is 3 meters. Any other length could also be supplied for special orders.

3-Pressure

Typical pressure classes of Faratec pipes are listed in the following table. Contact the manufacturer if you are requesting a higher working pressure. Faratec pipes can be produced up to 100 bars working pressure at lower diameters.

The working pressure of the pipes has been calculated according to AWWA M45 standard. Pressure classification is determined based on the maximum pressure at operation time and does not depend on the depth of the pipe burial.

Faratec pipes are manufactured in a wide range of diameters up to 4000 mm (157 inches) and maximum working pressure of 100 bars (1450 PSI). These pipes due to their structure could be designed for a variety of fluids with various pH conditions (acid or base) and have a high resistance to corrosion in chemical environments. Some of the mechanical properties of Faratec Uni-Axial and Bi-Axial pipes are shown in the table below compared to steel and GRE pipes.

Term Unit Uni-Axial Bi-Axial GRE Steel
Max axial tensile MPa 55.9 115 107.8 207
Max hoop tensile MPa 342.6 394 264.7 207
Axial modulus of elasticity GPa 9.4-11.7 10.7 12.7 207
Hoop modulus of elasticity GPa 9.2-32.9 19.4 17.6 207
Poisson's ratio --- 0.25 0.3 0.26 0.26
Specific gravity --- 2.0 2.0 1.8 7.8
Hazen-William's C --- 150 150 150 130

4- Pipeline Lisfspan tips

In order to ensure long lifespan service of the pipeline, the following tips should be noted:

Maximum test pressure in the factory based on pressure classification (AWWA C950, ASTM D3517) 2.0 × PN
Maximum field test pressure 1.5 × (Pw)

5-Water Hammer

Internal shocks, most notably water hammer effect, are due to a sudden change in fluid velocity inside the system which is usually caused by rapid closing or opening the valves, or the sudden start-stop of the pumps. Low modulus of elasticity of GRP pipes in comparison with metal pipes makes it possible to reduce water hammer effect in the system. Faratec pipes are able to withstand water hammer at various pressure levels according to the following formula. This approximate formula is used to determine the pressure changes at certain points in a direct pipeline, neglecting the slight friction loss.

6-Stiffness

Faratec pipes are manufactured in following standard stiffness:

Reference Unit Nominal Pipe Stiffness (SN)
ISO Pa 1250 2500 5000 10000 15000 20000
AWWA kN/m² 62 124 248 494 744 992

7-Flow Velocity

The permitted flow velocity in Faratec pipes is 3 m/s which could be increased in the absence of abrasive materials in the fluid up to 9 m/s. Please contact Farassan Company for more information.

8-Operating Temperature

Faratec pipes have the ability to be designed for fluid transfer temperatures up to 160 ºC. Maximum allowable fluid temperature in standard pipes produced with commonly used polyester resins is 45 °C. For continuous operation at a temperature between 50 °C and 60 °C it is recommended to consider one higher pressure class; e.g.: use a 10 bar pipe for 6 bars. At higher temperatures other resins with higher thermal resistance and special design are used. Please contact Farassan Company for more information.

It can be produce all fittings with different angles according to customer´s need.
