Plastic pvc well pipes can be divided into polyvinyl chloride (PVC) pipes, polyethylene (PE) pipes, polypropylene (PP) pipes, polybutylene (PB) pipes, ABS pipes, etc. according to their materials; they are mainly divided into vinyl chloride according to raw materials Materials (PVC, PVC-U, PVC-C, suitable for bonding and flexible connection of rubber rings) and polyolefin materials (PE, PP, PB, suitable for hot melt and electrofusion connections); according to the structure of the pipeline (And caliber), mainly divided into solid wall pipe, corrugated pipe (single wall, double wall), reinforced pipe, winding pipe, core foam pipe, inner spiral pipe and other structures; according to the application field, it is mainly divided into outdoor water supply Pipes, construction water supply pipes, construction drainage pipes, buried drainage pipes, gas pipes, protective casing pipes, agricultural pipes, industrial pipes, etc.
Plastics and plastics, plastics and metal composite pipes have developed rapidly. Cross-linked polyethylene (PE-X), ultra-high molecular weight polyethylene (UHMW-PE), heat-resistant polyethylene (PE-RT), modified polychloride The amount of plastic pipes such as ethylene (PVC-M) has also greatly increased; in terms of product structure, solid-wall pipes, corrugated pipes, ribbed pipes, winding pipes, core foam pipes, inner spiral pipes and other structural pipes are all There are production applications; the main applications of products have gradually expanded from infrastructure construction fields such as water supply, drainage, gas, heating, and communications, to industrial applications such as chemical, electric power, mining, and trenchless construction fields.
