sewer pipe frp grp pipe
FRP/GRP mortar pipe is composed of inner layer, wound layer, resin-mortar layer and external corrosion resist layer, it’s density is 1.7-2.1, equals to 1/5 of steel pipe, 1/4 of ductile iron pipe, it has excellent properties.
1. corrosion-resist, inner liner resin-rich layer, suitable resin be selected depends on different mediums, resin content is 90%, it ensure that FRPM pipe prevent from corrosion and leakage.
2. shock-resist, FRPM pipe has flexible joint-Spigot and Socket joint with double O rings, it will not bring delamination and cracking while deformation is 25%.
3. good hydraulic property, inner layer of FRPM pipe is very smooth, it’s roughness co efficiency is 0.0084, so it’s conveying capacity is excellent.
4. Health property
If GRP pipes be used for transferring drinking water, inner liner will be foodgrade resin, to meet drinking standard.
FRP/GRP mortar pipes be widely used for urban water supply and drainage, wastewater treatment plant, chemical, metallurgy etc.

FRP chemical process pipe, with vinyl ester resin, like DERAKANE411, SW901, DERAKANE470 etc resin and c-glass fiber
FRP insulation pipes, for transfer hot spring water, hot water etc in hotel, hospital, power plant
FRP jacking pipe, for non-trenching construction, when FRP pipes need to go through building, bridge, railway etc.
