FIBER REINFORCED PLASTIC PIPE FOR WATER SUPPLY AND DRAINAGE

摘要

A fiber reinforced plastic pipe for water supply and drainage is provided to reduce resistance which is applied to the pipe and manufacture a pipe with a large diameter by installing an inner pipe body which is combined with a plurality of unit members and an FRP(Fiberglass-Reinforced Plastic) outer shell in which reinforced fibers are circumferentially arranged. A fiber reinforced plastic pipe for water supply and drainage comprises an inner pipe body(10) and an FRP(Fiberglass-Reinforced Plastic) outer shell(20). The inner pipe body is combined with a plurality of hollow FRP unit members(11a) to form a closed section having a hollow part(12b). The FRP outer part covers an outer surface of the inner pipe body to place the reinforced fiber in a circumferential direction of the inner pipe body. Fillers(30) are filled in the unit members. The section of the inner pipe body is circular.
