Introduction of double flat wall steel-plastic composite drainage pipe

Introduction of double flat wall steel-plastic composite drainage pipe

The double-flat wall steel-plastic composite winding drainage pipe developed and produced recently by Jingzhou Liangcheng Science and Technology Co., Ltd. is prefabricated into "T" type plate belt with high density polyethylene (HDPE) as the main raw material. The plate belt is wound on the pipe forming machine and welded into a pipe. At the same time, the W-type steel belt bound by galvanized steel belt is embedded in the groove between the two plates, and PE is coated on the steel belt to become the third generation of new steel-plastic drainage pipe on the outer wall of the pipe.

PPR cold water pipe

PPR cold water pipe

PPR cold water pipe is formed by injection molding of random copolymerized polypropylene. PP-R is a new generation of pipe material, which is made by random and uniform polymerization (random copolymerization) in the molecular chain of about 5% of PP through the gas phase copolymerization process in the late 1980s. With its non-toxic, durable, easy installation and other characteristics, Liangcheng PPR pipe is widely used in cold water pipes in engineering, water conservancy, industry and other fields.
