Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
FRP insulated pipe is a kind of light, high strength and corrosion resistant nonmetal pipe.
The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Because of its excellent chemical resistance, light weight, high strength, no scaling and strong seismic resistance, the glass steel sand inclusion has the advantages of long service life, low overall cost, quick installation, safety and reliability compared with ordinary steel tubes.
It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer.
