The pvc pipe may not be familiar to most people. Its main component is polyvinyl chloride. It is not so heat-resistant and tough. It is only added to other ingredients during processing to enhance these properties. And extensibility. The film on the surface of the pipe is a layer of lacquer, the main component of which is polyvinyl chloride, and the lowermost layer is a back-coated adhesive.

PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but because soft PVC contains softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its scope of use has been limited. Hard PVC does not contain softener, so it has good flexibility, easy to form, is not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value.

Pvc has poor combustion performance and is extinguished from fire. It is a flame retardant plastic; in addition to having an electrical insulation property, it is suitable for protective sleeves for wires and cables; hydraulic pressure resistance, external pressure strength and resistance of pvc pipes The impact strength is very high, and it is suitable for piping engineering under various conditions. It is widely used in PVC pipe fitting manufacturers.

The outer diameter of the pvc pipe generally has the following dimensions:

Pvc threading pipe is: 16 / 20 / 25 / 30 / 40 / 50 / 75 / 90 / 110;

The pvc drains are: 40/ 50/ 75/ 90/ 110/ 160/ 200/ 250/ 315/ 400/500;

The pvc water supply pipes are: 20/ 25/ 32/ 40/ 50/ 63/ 75/ 90/ 110/ 160/ 200.

The above specifications are in the following units: mm (mm)
