Fiberglass GRP FRP Pipes for Potable Water Transfer

FRP Pipe/FRP Tank/Filament Winding Machine/Electrolytic Cell/FRP GratingMachine/FRP Pultrusion Machine

FRP (fiberglass reinforced plastic) 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 pipe is consisted of inner liner, interface, structural layer, and outer surface layer.
     Inner liner is 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.
   Exterior surface shall consist of a chopped strand glass over which a resin-rich coating shall be applied.
  Inspection and test of FRP pipes shall be peroformed according to  ASTM D2996, AWWA C950, ANSI etc.
1.Appearance
The inner surface of the FRP pipe should be smooth and even, no crack, delamination, pinhole, impurity, poor gel area and air bubble, the ends of the pipe should be even and uniform, no burr and exposed fiber. 

Main Features of FRP Pipe
1. Structure of FRP Process Pipe Description
1) Antifouling, anti-moth, non-rust, keeping water from pollution; It also apply to carry the polluted water, slurry and seawater;
2) The ability of water resistance and corrosion resistance can prolong product service life;
3) The connection of insert makes airproof excellent; project cost can be reduced without building concrete protect layer;
4) Few joint and various of joint methods not only reduce water resistance but also project cost;
5) Good insulation, heat resistance, combustration resistance; No distortion in high temperature of 80-100 degree;
6) With light weight, high strength, the hoisting cost can be decreased, also expedite installation proceeding;
7) Low maintenance expense
2. 1) Corrosion resistance
2) Lightweighta high strength
3) Easy installation
4) Low temperature-perform
3.Connection method:
   Connection way can be adopted screw connection, spigot and socket connection, flange connection, plain end butt connection, sleeve connection, etc.
