There are many places in the city where steel pipes are used. Fire-fighting steel-plastic composite pipes are used especially in groundwater applications. In order to adapt to the needs of different environments, the types of steel pipes are also increasing. Similarly, we need to have a full understanding of them before using steel pipes. The following editor tells you some relevant knowledge about plastic-coated steel pipes. I believe everyone will be interested in this knowledge.

Tell the relevant knowledge of plastic-coated steel pipe. The inner layer of the plastic-coated steel pipe is food-grade epoxy resin and the outer layer is modified epoxy powder coating. The inner and outer walls are melted, sprayed or absorbed by the advanced technology. A new type of composite pipe cured at high temperature. As a replacement product for ordinary water pipes, it not only has the strength and rigidity of steel pipes and pipe fittings, but also has a very smooth inner wall of plastic water pipes, good self-lubrication, no rust, no scaling, and fluid It has the advantages of low resistance, erosion resistance, corrosion resistance, good antibacterial and hygienic performance, and flexibility. Compared with the lined steel/plastic composite pipe: the plastic-coated composite steel pipe has a lower linear expansion coefficient, no reduction in diameter, and food-grade epoxy resin is a polar material, which has a strong binding force with the steel pipe. There will be no separation or shedding in the next long time, especially in terms of resistance to thermal expansion and contraction, and better weather resistance. I understand the relevant knowledge of plastic-coated steel pipes. It is very helpful for using it. After reading the article, many people may find that it has many advantages. Although it has many advantages, it still needs more attention in the actual operation process. These products must be operated in the correct way during installation. If the composite pipe is installed incorrectly, the steel-plastic composite pipe has the advantages of no way to operate.

After the ordinary galvanized water pipe is used for a few years, a large amount of rust will be produced in the pipe. The yellow water flowing out will not only pollute the tableware, but also seriously endanger our health due to the high content of heavy metals. Copper pipes and stainless steel pipes have corrosion resistance compared with galvanized water pipes. Sterilization, safety, and health are the first-class products in water pipes, but copper pipes have fast heat conduction, high prices, and high welding costs, which do not meet the purchase requirements of ordinary households. The stainless steel pipe is not only widely used in households, but also one of the outstanding materials in the medical, food, beverage, tableware and other industries. It is currently the most widely used, safest and sanitary water pipe with zero pollution.

Compared with the domestic trial, the steel-plastic composite pipe is more suitable for large-caliber geographic management such as sewage resource treatment, drainage systems, heating pipelines, etc. The new product of the steel-plastic composite pipe has been paid attention to by major enterprises and news media. Its product characteristics are: :

1. Hygiene, non-toxic, no accumulation of dogs, no breeding of microorganisms, and guarantee of fluid quality

2. Resistant to chemical corrosion, soil and marine organism corrosion, and cathodic disbondment resistance

3. The installation process is mature, convenient and fast, and the connection is similar to ordinary galvanized pipe

4. Good weather resistance, suitable for harsh environments such as deserts and saline-alkali

5. The pipe wall is smooth, the transmission efficiency is improved, and the service life is long. Because of the excellent performance of the steel-plastic composite pipe, many power plants are widely used in the acid and alkali pipes in the worst chemical water system, thus showing Its broad application prospects.
