Introduction:
HDPE Winding Reinforced pipe (full name of high-density polyethylene structural wall hot winding tube) is a kind of special-shaped structural wall pipe made by spiral winding process with smooth inner wall and spiral shaped reinforcing rib outer wall, which belongs to flexible pipe. Krah pipes are made of high-density polyethylene by winding forming process in the hot melt state, and are cooled by rolling air cooling before demoulding in the hot state. The pipes gradually dissipate heat and have uniform wall thickness. Krah pipe adopts socket electric fusion connection. Both ends of the pipe are processed into socket and spigot during production, and electric fuse wire is embedded at the socket end. When the pipe is socket connected, only the power supply is connected to complete the welding, which can make the pipeline system achieve zero leakage. This kind of pipe is widely used in urban drainage, municipal drainage, electric power, petrochemical and other fields, and is an ideal replacement for reinforced concrete and cast iron pipes.
Features
Krah pipe is the equipment, technology, process and production process introduced from Germany. High density polyethylene resin (HDPE) is used as the main raw material, and polypropylene (PP) corrugated pipe is used as the auxiliary support pipe for hot winding and natural wind molding. High density polyethylene (HDPE) winding reinforced pipes are flexible pipes with reasonable structure design and novel production process. The products are divided into three series: PR, SQ and VW. Our company can provide users with pipes and pipe fittings with inner diameter of DN300mm-DN4000mm and standard length of 6m. The product meets the requirements of European Standard PrEN-13476 and national standard GB/T19472.2-2004.
