High density polyethylene winding reinforced pipe (carat pipe) is a kind of special-shaped structural wall pipe made by spiral winding technology with smooth inner wall and spiral shape reinforced rib. Products implement the national standard (GB/T1947.2-2004) "Buried polyethylene (PE) structural wall pipe system Part 2: polyethylene winding structural wall pipe" B-type structural wall pipe part and German standard DIN16961 standard, design, construction and acceptance comply with (CECS164↵2004) "buried polyethylene drainage pipe pipe tao engineering technical Regulations.

HDPE winding reinforced pipe is made of high density polyethylene as raw material, which is made by winding molding process in hot melt state, and is cooled by rolling wind before being demoulded in hot state. The pipe gradually dissipates heat and the wall thickness is uniform. HDPE winding reinforced pipe adopts socket fusion connection, the pipe two acha is processed into socket and socket during production, and the electric fuse is embedded in the socket end, and the welding can be completed by simply accessing the power supply when the pipe is connected, and the pipe system can achieve zero leakage. The product is widely used in urban drainage, municipal drainage, electricity, petrochemical, coal mine ventilation and other fields, is the ideal replacement of reinforced concrete, cast iron pipe products.
