FRP pipe is a kind of high-strength, lightweight, corrosion-resistant non- llic pipe. The manufacturing method is to wind the resin- d heavy glass fiber by on the rotating mandrel according to the process requirements, and evenly spread quartz sand between the fibers as a long distance sand .

Compared with ordinary pipes, GRP pipes are accepted by users because of their excellent chemical resistance, light weight, high strength, non-scaling, strong impact resistance, long service life, low comprehensive cost, fast installation, safety and reliability. FRP pipes are often used in petroleum, chemical and drainage industries. The production of GRP pipes in China is developing rapidly, and the output is increasing year by year. Its application scope and departments are also becoming wider and wider. GRP pipes are made of resin (food grade resin used to transport drinking water), glass fiber and quartz sand as raw materials by special process. Compared with traditional pipelines, it has obvious advantages:

1、 It has excellent corrosion resistance.

2、 There is no need to take anti-corrosion measures, which will not cause secondary pollution to the natural environment.

3、 The product has a long service life.

4、 The pipe weight only accounts for 1/4 of the ductile iron pipe of the same specification and length and 1/10 of the cement pipe. It is convenient for transportation, loading and unloading, and installation.

5、 Reduce the number and difficulty of pipe joints, accelerate the construction speed and improve the quality of the whole pipeline.

6、 Increase flow rate and reduce energy consumption. Using pipes with smaller diameter to transport the same flow rate can increase the flow rate by about 10% compared with steel pipes with the same specification. No scaling. The cable protection effect under interference and corrosion environment is good. GRP pipes are environmentally sound and their application scope is expanding year by year.
