Coated steel in large diameter spiral welded pipe and high-frequency welded pipe made of plastic coating is on the basis of a maximum nozzle diameter 1200mm, which can be coated with polyvinyl chloride according to different needs (PVC), polyethylene (PE), epoxy resin (EPOZY) and other various properties of plastic coated Layers, good adhesion, corrosion resistance, and can be resistant to acid, alkali and other chemical corrosion, non-toxic, non-corrosion, wear, impact resistance, strong penetration, pipe surface is smooth, does not adhere to any substance that can reduce the transmission time of resistance, to improve traffic and transportation efficiency, reduce delivery pressure power loss. Solvent-free coating, no leakage of material, which does not pollute the transmission medium, in order to ensure fluid purity and health, in the range of -40 ℃ to 80 ℃ hot and cold cycles can be used interchangeably, not aging, not cracking, which can be harsh in the cold zone, etc.

The standard and application of large diameter thick-walled pipe for water engineering
Steel-plastic composite pipe with hot dip galvanized steel pipe as a matrix, by melting powder coating technology in the wall (wall also required) coating made of plastics, performance. Compared with galvanized pipe, with anti-corrosion, no rust, no fouling, smooth, smooth, clean non-toxic, long life, etc. According to the test, the service life of steel-plastic composite pipe more than three times as galvanized pipe. Compared with the plastic pipe, with high mechanical strength, pressure, heat and good benefits. As the substrate is steel, so there is no embrittlement, aging. It can be widely used in water, gas, chemical production.Products such as fluid transport and heating project is the upgrading of galvanized pipe products. Since its installation and use the same traditional galvanized pipe, pipe forms are identical, and can replace the aluminum-plastic composite pipe in large diameter water transmission play a role by users, has become the most competitive oil pipeline of new products.
