PPR Fiber-glass(FR-PPR) Composite Pipes make use of 100% imported raw materials,and thus guarantee its product quality. This high-performance pipe is produced through multi-layer co-extrusion at low temperature and high speed by special technique and equipent.This pipe has 3 layers,in which the internal and external layer is made of PP-R materials,while the middle layer is stiffened and rein forced composite materials.PP-R materials of internal layer ensure the hygiene of this pipe;the middle layer stiffens and reinforced this pipe,and reduces coefficient of linear expansion;PP-R materials of external layer facilitate its hot-melting and socket connection with teaditional PP-R pipes.This pipe is equipped with 5 series of pressure class,including S2,S2.5,S4andS5,which are designed of hot water conveying system.Its nominal outside diameter has over 10 specitications,which ranges from 20 mm to 63 mm.
