At this stage, the distribution of processing capacity of hard pvc pipes in my country is structurally unreasonable. The processing capacity of small and medium-sized enterprises is mainly concentrated in pvc drainage pipes. At the same time, a large number of non-standard pipes still flood most of the market, leading to disorderly and chaotic market competition, and the prices of PVC pipes are also disorderly.

According to the market research center, the full name of PVC is Polyvinylchlorid, and its main component is polyvinyl chloride. In addition, other proportioning components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. In our daily life, there are two types of PVC pipes, hard PVC pipes and soft PVC pipes. Among them, hard PVC pipes have a nominal outer diameter of 50 cm, but soft PVC pipes generally have a maximum outer diameter of 50 mm.
