At present, in the steel pipe market, the specifications of internal and external plastic-coated steel pipes are relatively comprehensive and complete, and all products supplied can meet the relevant quality standards formulated by the state.
Internal and external plastic-coated steel pipes are a composite pipe material. While having the performance of steel pipes (such as high strength and high rigidity), they also have the performance of plastic pipes (such as high smoothness and excellent corrosion resistance). Therefore, internal and external plastic-coated steel pipes can be used in various liquid transportation fields, such as cold water, hot water, sewage, medicine, chemical industry, etc.
First, the characteristics of internal and external plastic-coated steel pipe products:
1. The base pipe uses high-quality steel pipes, and the inner wall uses food-grade sanitary coatings. Therefore, the internal and external plastic-coated steel pipes are hygienic and will not produce chemical reactions. They are green and environmentally friendly building materials.
2. The production adopts the homogeneous hot-melt connection process, which allows you to complete the installation work in a shorter time, which is simple, convenient, time-saving and labor-saving.
3. The coefficient of thermal conductivity is very low, only 50% of that of metal pipes. Therefore, in the process of hot water transportation, the heat loss is very small, and it has good energy-saving and heat-insulating performance.
4. The overall weight of the internal and external plastic-coated steel pipe is about 10% of that of the steel pipe, but the pressure resistance, impact resistance, heat resistance and toughness are higher than those of the steel pipe, and it has the characteristics of light weight and high strength.
5. The special coating used inside and outside has a good finish so that the resistance generated when transporting liquid is small, which can greatly reduce energy consumption.
6. The selected materials have high corrosion resistance, and can also avoid scaling during use, which can prevent the blockage of steel pipes and the generation of yellow spots and rust.
7. Long service life.
Second, the performance of internal and external plastic-coated steel pipes:
1. The adhesion of the internal and external coatings of the steel pipe will be significantly enhanced compared to others, and the materials used in the coating have good electrical insulation, which makes the steel pipe more excellent in impact resistance and pressure bearing, and will not produce embrittlement and electrical corrosion.
2. The environmentally friendly and harmless internal and external coating products are not easy to accumulate dirt, nor will they breed other microorganisms, which can well ensure the quality of the liquid in the steel pipe.
3. The physical properties of the steel pipe are good and the chemical reaction is very weak, so it is not easy to corrode or peel off, and can be used in harsh environments.
4. The inner wall of the steel pipe has good finish, which can not only improve the transportation efficiency, but also extend its service life.
5. Similar to the installation method of traditional galvanized steel pipes, the installation process is relatively simple and convenient.
