Because chemical building materials products have good corrosion resistance, light weight, low energy consumption in production and application, and convenient construction, plastic well wall pipes made of chemical materials are widely used in the process of engineering construction, urban construction, and village construction. middle. Although the development history of chemical building materials in my country is relatively short, the development of chemical building materials in my country is rapid, and the fields of pipelines, doors and windows, waterproof materials, coatings, etc. have all been fully developed.
The classification of plastic well wall pipes can be distinguished from their materials and the main fields of use. From the perspective of different classifications of chemical materials, plastic pipes can be divided into polyvinyl chloride (PVC) pipes, polyethylene (PE) pipes, polypropylene (PP) pipes, polybutylene (PB) pipes, ABS pipes, etc. Generally speaking, HDPE (high density PE), LDPE (low density PE) and other PE pipes are collectively referred to as PE pipes, while PVC-C and PVC-U pipes are collectively referred to as PVC pipes. The PVC piping system was the first to develop and was used in large quantities. PE and PP pipes developed late, but they have grown rapidly in recent years. The world has formed an industrial pattern dominated by PVC-U, PE and PPR pipes.
