Plastic-coated steel pipes are used everywhere in life, such as building water supply pipes, fire water supply pipes, special pipes for coal mines, hot spring anti-corrosion and thermal insulation pipes, and cable protection pipes commonly seen in modern life. Common steel-plastic composite pipes are actually mainly plastic-lined steel pipes and plastic-coated steel pipes. The following is an explanation of the application of plastic-coated steel pipes. According to the different internal and external coating materials, they can be divided into epoxy resin coated steel pipes and polyethylene coated steel pipes. Both are based on welded steel pipes and seamless steel pipes. They are green and environmentally friendly pipes that are corrosion-resistant, […]

Internal and external plastic-coated steel pipes for water supply have the following characteristics: First, the inner surface of the internal and external plastic-coated steel pipes has a plastic coating, which can keep the inside of the pipe smooth, reduce the resistance to water flow, and increase the flow of water. In addition, because the water volume is relatively smooth, the water flow needs can be ensured. At the same time, no scaling will occur inside the pipeline during use, and bacteria will not breed, reducing water pollution. Second, the outer surface of the internal and external plastic-coated steel pipes has a plastic coating, which can increase the adaptability of the […]

When plated parts need to be stacked closely together for storage and transportation, adequate precautions should be taken to prevent white rust. Maintaining a low humidity environment around the plated parts and ensuring adequate ventilation between stacked plated parts can prevent white rust. Minimize it. Specific precautions are described below. one. Surface treatment can be used to reduce the occurrence of white rust on the coating. Galvanized pipes and hollow plated parts can be coated with a layer of varnish after galvanizing. Products such as wires, plates and mesh materials can be waxed and oiled. Hot-dip galvanized structural parts can be subjected to chromium-free passivation after water cooling. deal with. […]

There is a cleaning and cleaning step in the maintenance of internal and external plastic-coated steel pipes, so the cleaning step is also very important. How can it be implemented well? Steel Pipe has some detailed introduction in these aspects. I hope everyone can learn this. Cleaning of internal and external plastic-coated steel pipes uses solvents and emulsions to clean the surface of the steel to achieve the effect of removing oil, grease, dust, lubricants and similar organic matter. However, it cannot remove rust, oxide scale, welding flux, etc. on the surface of the steel, so it is not suitable for anti-corrosion production. It is only used as an auxiliary […]
