Glass fiber reinforced plastics (GRP) are a composite material made of a polymer matrix reinforced with fibers. GRP pipes is designed for corrosion resistance, weather resistance, visual inspection friendliness, and durability. For special design requirements, Weitong also offers custom GRP pipe solutions.

Product details

FRP Pipes, also named GRP pipes. FRP process pipe is a new type of composite pipe with excellent performance. It has excellent performance that other traditional pipes (metal pipes, concrete pipes, plastic pipes) can't match, and it has the characteristics of corrosion resistance, wear resistance, heat resistance and so on. The glass fiber pipes produced by our company are widely used in the fields of desulphurization, denitrification and seawater desalination. Contact the FRP pipe manufacturer.

Features of FRP/GRP Pipes

1.Corrosion Resistance

FRP pipes are made of a hybrid material that combines glass fiber and polyester resin. FRP is a non-reactive composite with excellent corrosion tolerance, chemical resistance, and weathering resistance.


FRP Pipes can be rendered in exact accordance to the laws of forces governing the construction of pipe that will come into contact with potable water and foodstuffs thanks to filament winding processing technologies combined with polymerization and vaporization processes.

3.Hydraulic Efficiency

GRP pipes with a smooth internal surface have a high “c” rating, allowing them to carry a high flow at a low frictional head loss, reducing pumping costs and saving energy.

4.Longer Service Life

The hydraulic design base (HDB) of GRP Pipes is such that it would have a protection factor of 1.8 times its pressure class even after 50 years of continuous operation. In comparison to C.I., STEEL, G.I., and P.S.C. Pipes, GRP Pipes can have a much longer operating life, longevity, and performance at a much lower life-cycle expense.

5.Surge Pressure

Strong surge pressure tolerance in contrast to steel and C.I. pipes, GRP pipes have a greater resistance to surge strain and a higher stiffness, which ensures they have a lower risk of bursting due to water hammer.


As compared to other components, GRP pipes have a lower strength-to-weight ratio. It is low in weight due to the use of 1/10 P.S.C., 1/5 steel, and 1/8 C.I. As a consequence, GRP Pipes are simple and convenient to add, manage, change, and fix.

7.Low Thermal & Electrical Inductivity

GRP Pipes have exceptional thermal insulating properties, so they don’t need to be coated on the outside to keep the temperature within the pipe constant. For GRP Pipes, cathodic security is also not needed.
