Epoxy resin coated steel pipe manufacturer

Description :

　　The advantages of epoxy resin coated steel pipes are good anti-corrosion performance, with a service life of up to 50 years and a beautiful appearance. The disadvantage is that they cannot be bent and need to be repaired after being firmly connected on site. Shengcang coated steel pipe related knowledge introduction: The coating surface of water supply coated steel pipes is smooth, beautiful, and the external color can be freely selected. Due to its smooth inner wall, it can prevent the growth of microorganisms, reduce fluid resistance during transportation, increase flow rate, save energy, and is used in various water supply and drainage projects. Mainly used for the transportation of drinking water supply pipelines, as well as seawater, recycled water, chemical and petroleum industries, and most acids, alkalis, and salts. It is particularly suitable for buried transportation pipelines with a service life of up to 50 years. The scope of plastic coated steel pipes is relatively wide. Any steel pipe that undergoes chemical treatment on the inner or outer layer belongs to the scope of plastic coated steel pipes. Common chemical substances used for plastic coating on the outer layer of steel pipes are polyethylene, epoxy resin, and other coatings. After plastic coating processing, the steel pipe has a longer service life than the previous pipe body, generally up to 50 years. However, the steel pipe after plastic coating changes the characteristics of the original pipe body, so attention must be paid when laying it. The characteristics of coated steel pipes: They have anti-corrosion and anti rust properties. The epoxy resin coated anti-corrosion spiral steel pipe manufacturing factory has a very smooth inner wall and minimal friction resistance, which can be used for pipelines for edible oil or drinking water. Moreover, bright colored paint can be applied to the outer wall of the pipeline, making it more aesthetically pleasing. Moreover, compared to traditional pipelines that are prone to brittleness or rust, the service life of coated steel pipes can reach more than 20 years, which is quite low in terms of total cost.

　　(1) First, weld flanges on both ends of the steel pipe. The flanges should be firmly welded and then coated with polyethylene. During installation, install a sealing gasket between the two flanges of the coated composite pipe and tighten it with bolts.

　　(2) To ensure that the pipeline does not experience axial movement under pressure or water hammer, it should be fixed using supports, brackets, hangers, etc. When fixing, it should be considered that the pipeline will not shift when phenomena such as swinging and bending under pressure occur. For pipes installed vertically, the distance between two fixed points should not exceed 2m. For horizontal installation, the distance between two fixed points should not exceed 750mm when the nominal outer diameter of the coated composite pipe is less than 76mm, and not exceed 1100mm when the nominal outer diameter of the coated composite pipe is not less than 76mm.

　　(3) When fixed with cement or brick supports, the pipeline can be built in the supports. When using brackets, racks, or hangers for fixation, U-shaped or other types of pipe clamps need to be installed on the pipes or fittings. Due to the smooth surface of the pipe, in order to prevent the pipe clamp from sliding, a rubber pad should be placed between the pipe surface and the pipe clamp, and the pipe clamp should be tightened with screws to prevent it from sliding. Then, the pipe clamp should be firmly connected to the support pier, bracket, support, etc. through bolts, etc.
