The base pipe of the coating is a seamless steel pipe and should meet the requirements of GB/T8163 for the base pipe. The base pipe of other steel pipes should meet the requirements of the industry standard for the base pipe. The above are the capabilities and construction requirements of plastic-coated steel pipes. Pay attention to these issues during construction to ensure correct use. Once the internal and external plastic-coated composite steel pipes were marketed, they were greatly welcomed by the market. They quickly replaced various steel pipes, including galvanized pipes, stainless steel pipes, copper pipes, threaded pipes, and other steel pipes. The use of steel pipes has gradually expanded and has been warmly praised by people. Compared with the previous steel pipes, this is exactly what the galvanized steel pipes of the past could not do. It solves the corrosion of metal steel pipes due to water supply, burial, acid, and salt, and greatly improves the service life of steel pipes. Fire-fighting steel-plastic composite pipes are steel-plastic composite pipes made by high-frequency welded steel pipes through special processes, and a layer of epoxy resin material is welded inside and outside the steel pipes at high temperature.

The following will introduce you in detail to the problem of pores in water supply plastic-coated steel pipes. It has many advantages. The first is the corrosion resistance inside and outside. The inner and outer walls of the plastic-coated steel pipes have been treated with a plastic coating. It can be used to transport highly corrosive fluids and can also be buried in those highly corrosive environments. Secondly, the inventory of the steel circulation market is stable and declining.

The price of plastic-coated pipes inside and outside is reasonable. Chemical cleaning can certainly make the surface reach a certain degree of cleanliness and roughness, but its anchor pattern is shallow and it is easy to pollute the environment. It is widely used in water supply, industry, fire protection, communications, electricity, and other high-quality construction projects with high and low temperature resistance. It is a green product for pipe renewal in the 21st century. It can be used as a heat-resistant and anti-corrosion material for building water supply and drainage, cold and hot circulating water steel pipes, and can be used for steel pipe anti-corrosion in seawater circulation systems and chemical systems. It has strong corrosion resistance, drag reduction, anti-corrosion, pressure resistance, antibacterial, and other functions, and has good chemical stability and water resistance.

Designated manufacturer of plastic-coated composite steel pipe for fire-fighting steel pipe, especially in the coating and coating of steel pipe outer wall, corrosion detection of steel pipe, repair of steel pipe, and internal cleaning of steel pipe, research and development of many new materials and technologies, provide favorable protection for steel pipe safety. Generally, chemical steel pipes are buried more deeply, and the previous steel pipes cannot withstand such a harsh use environment as buried, so the aging of previous generations of chemical steel pipes is accelerated, and even leakage occurs. The plastic-coated steel pipe for the chemical industry has changed this situation, so it is also known by more and more chemical plants.

Become a steel pipe in the chemical industry. The tower frame is connected by the tower pole device, and the tower pole is made of steel. The surface of the tower pole steel is hot-dip plastic-compounded with a modified polyethylene plastic layer on the inner and outer surfaces. And ordinary steel pipes may rust easily. The construction procedure of plastic coated steel pipes should meet the following requirements: plastic coated steel pipes should not be buried in reinforced concrete structural layers; welding is prohibited during the installation of plastic coated steel pipes; plastic coated steel pipes should be gradually connected from large diameter to small diameter, and the pipe mouth should be sealed in time; plastic coated steel pipes are strictly prohibited from being thrown and violently hit during transportation, loading and unloading and construction on site; when installing plastic coated steel pipes, pipe bending machines can be used for cold bending when the pipe diameter is not greater than DN50.

Coated steel pipes for underground coal mines: Coated steel pipes for underground coal mines are composite products with antistatic, flame retardant, and corrosion resistance obtained by treating the base steel pipe with a special process and coating the inside and outside of the steel pipe with a special powder material. They overcome the multiple defects of the steel pipe itself, such as easy rust, corrosion, high pollution, and low strength and easy deformation of plastic pipes, and integrate the common advantages of steel pipes and plastic products. They are energy-saving and environmentally friendly products that are promoted for use. It is widely used in the construction of steel pipe systems such as electricity, communications, transportation, municipal administration, and mining in various regions of the country. It is a product for protecting cables across bridges and roads.

Fire-fighting steel pipes are indispensable. Internal and external plastic-coated fire-fighting pipes are the leaders in the current fire-fighting pipe industry. Next, Yutian Steel Pipe will study and study the relevant issues before the use of internal and external plastic-coated fire-fighting pipes with you. Before installing fire-fighting steel pipes, you must choose what kind of steel pipe to install and what kind of steel pipe is suitable. A good fire-fighting system not only relies on good steel pipes, but also other parts, fire hydrants and other products must meet the standards, which can greatly extend the service life of the fire-fighting system. Users can choose according to their conditions. The airtightness of each part should be good. Purchase these products and then install the steel pipe, which not only shortens the installation time of the fire-fighting system, but also saves the human body. Fire-fighting plastic-coated pipe fittings have the advantages of a smooth inner wall, small friction resistance, and no scaling, and the outer wall is more beautiful and luxurious.

The inner layer of fire-fighting plastic-coated pipe fittings should be anti-pollution, and measures need to be improved. The following is the detailed practice: Generally, fire-fighting plastic-coated pipe fittings use the connection method of traditional pipe fittings. The materials used and the plastic coating layer are different. According to different application environments, suitable plastic-coated steel pipes are selected, which can greatly reduce the aging speed of plastic-coated steel pipes due to the incompatibility of materials and the environment, and improve the service life of steel pipes. The anti-corrosion structure is 6 oils and 3 cloths, with a total film thickness of 600μm. Professional construction engineers go to the site for construction guidance. For example, the material used in the fire protection steel pipe system is epoxy resin, and the cable protection sleeve uses polyethylene. Because the particle density of epoxy resin is much higher than that of polyethylene, the fire protection top uses epoxy resin to make the steel pipe wall more lubricated and less likely to be blocked. In addition, in outdoor open-air environments, it is recommended to use galvanized steel pipes with inner plastic coatings. If inner and outer plastic-coated steel pipes are used in outdoor environments, long-term exposure to sunlight and human damage can accelerate the degree of peeling of the outer wall coating. The anti-corrosion of water supply steel pipes adopts the extra-enhanced anti-corrosion level. It is recommended to use inner and outer plastic-coated steel pipes. The acidic and alkaline moisture in the soil can continuously corrode the steel pipes for a long time.
