What's FRP Pipe?

   FRP pipe is a new kind of pipe material used for fluid transportation in recent years. Because of its excellent properties, it has been used extensively on the market. The reciprocal filament winding process has the advantages of high strength, reasonable jointing type, convenient installation, speedy test of the leakage test to the joint, it mainly be used for buried pipeline and long-distance transfer pipeline.

The length-fixed winding process is controlled by computer. Manufacture the liner on the mandrel as the same process of fiber glass winding pipe, then after the resin became hardened, make the structure layer by winding according to the designed linearity and thickness, and add the mixture of mortar and resin into the structure layer, finally, wind the outer protection layer.

The pipe is consisted of inner liner, interface, structural layer, and outer surface layer.

Inner liner corrosive resistance layer, Surfaces exposed to the chemical environment shall be resin-rich and reinforced with a 10 or 20 mil thick chemical surfacing mat (E- glass).

Interface layer is leakage proof layer, it be reinforced by minimum of three layers of 1.5 oz chopped strand mat.

Structural layer will be reinforced by continuous strand fiberglass roving and shall maintain a resin content of 20-40%. It is reinforcement for the inner lining layer and interface, resisting the foreign load to the pipe body and ensures the strength and stiffness of the pipe body.

The exterior surface shall consist of a chopped strand glass over which a resin-rich coating shall be applied.

FRP Process Pipes

Characteristics of FRP Pipes

1.Good corrosion-resustant

2.Lightweight and high strength
3.Installation conveniently

4.Smooth inner surface has good property of circulation5.Good low temperature-resistant

6.Good thermal insulation

   Used in chemical industry and other field of acid resistant or alkali resistant
