GRP pipeline - Glassfiber Reinforced Plastic Pipe
Sand filler GRP pipe - Glassfiber Reinforced Plastic Pipe

GRP pipe with sand filler
Nominal diameter DN400—DN4000
Pressure rating range 0.6MPa—2.5MPa
Length: 12m
Stiffness 1250Pa—10000Pa
Raw materials: unsaturated polyester resin, continuous glass fiber
Manufacturing technics Same as standard GRP pipe fabricate through filament winding and control by computer, the different point is the middle layer was a special layer with resin and mortar. Adopt food grade resin and special post curing technics, which can use as food grade pipeline and for water transportation.
