| Commonly used steel pipe - plastic composite pipe, large diameter coated steel pipe Plastic composite pipe, hot dip galvanized steel substrate, the outer wall can also be in the wall (when needed) coated plastic made by the powder melting spray performance. Compared with galvanized pipe, with the advantages of corrosion-resistant, not rust, not fouling, smooth, smooth and clean non-toxic, long life. According to three times of testing, the service life of plastic composite pipe for galvanized pipe. Compared with the plastic tube, with a high mechanical strength, pressure resistance, heat resistance, etc.. As the substrate is a steel pipe, so there is no embrittlement problem of aging. Can be widely applied to water, gas, chemical products, such as fluid transport and heating project is the upgrading of products galvanized pipe. Pipe market due to its installation method is basically the same as with traditional galvanized pipe, pipe fitting forms are identical, and can replace the plastic composite pipe on the transportation of large diameter water play a role welcomed by users, has become the most competitive one of the new products. Coated steel pipe is made in a plastic coating on the basis of large-diameter spiral welded pipe and high-frequency welded pipe, the largest nozzle diameter up to 1200mm, depending on the needs coating of polyvinyl chloride (PVC), polyethylene ( PE), epoxy (EPOZY) and other various properties of plastic coating, good adhesion, corrosion resistance, can be resistant to acid, alkali and other chemical corrosion, non-toxic, does not rust, wear and impact resistance permeation resistance, smooth surface pipeline, and will not adhere to any substance, can reduce the transmission of resistance, increase traffic and transport efficiency, reduce the delivery pressure losses. Solvent-free coating, no oozing substance, and thus will not the transmission medium of pollution in order to ensure the purity and health of the fluid at -40 ℃ to +80 ℃ range of thermal cycles used interchangeably, not aging. no cracks, and thus can be used in the cold zone and other harsh environment. Large diameter coated steel pipes are widely used in tap water, natural gas, petroleum, chemical, pharmaceutical, telecommunications, power, marine and other engineering fields.
