FRP pipes are made by special processes with resin as the matrix and glass fibers as the reinforcing material. This type of pipe has advantages such as corrosion resistance, leak prevention, and good heat insulation performance.

It features light weight, high strength, maintenance-free, long service life, strong designability, low fluid resistance, convenient installation, and low overall cost.

It can be widely applied in industries such as petroleum, chemical engineering, pharmaceuticals, electricity, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transmission, mining, etc., and is an ideal pipe for transporting liquids and gases.
