Comparison of Plastic Pipes and Traditional Metal Pipes

Advantages: Compared with traditional metal pipes, plastic pipes have the characteristics of light weight, corrosion resistance, high compressive strength, sanitary safety, low water flow resistance, energy saving, metal saving, improved living environment, long service life, safety and convenience. Favored by the pipeline engineering community.

Disadvantages: 1. When recycling waste plastic pipes, classification is very difficult and economically uneconomical. 2. Plastic pipes are easy to burn, and when a fire or other accident occurs, the plastic pipe generates toxic gas when it burns. For example, when polystyrene is burned, toluene is produced. A small amount of this substance may cause blindness, inhalation and vomiting, etc., and the burning of PVC material may also generate hydrogen chloride toxic gas. In addition to burning, it is a high temperature environment, which may cause the corresponding plastic material to decompose toxic components. For example, a benzene ring or the like. 3. The supply of plastic pipes is limited because plastic pipes are made of petroleum-refined products and petroleum resources are limited. 4. Many plastic raw materials made of pipes are non-degradable plastics, so it will bring a large amount of waste materials to the society.
