Product Description

GRP/ FRP Fiberglass Pipe for Hydroelectric Power Station
The Fiber-Glass-Reinforced Plastic Pipe (GRP Pipe)
The Fiber-Glass-Reinforced Plastic Pipes (GRP Pipe) adopt the reciprocating-cross-winding wet sand-adding process, and the structure of the GRP Pipe wall consists of  the inner liner, the structural layer, the sand-adding layer and the surface layer .
Main raw material:
esin  ,surfacing mat, chopped fiber ,silica sand ,continuous glass fibre and other accessories etc.
Product specification :
Pipes are manufactured in length between 6m-12m  (DN300mm-DN2600mm) . also be manufactured special length depending on the desired length according to the project needs. At same time with  elbow ,tee,flange,Y-junction,T- junction and special pipe etc.
The sand pipe executive standard  : 
 National standard GB/T21238-2007 "Glass fiber reinforced plastic sand pipe"
