Gangsu composite tube, large diameter coated steel pipe

Inspecting &controlling in hot dip galvanized structural steel pipe as substrate, the molten powder spraying technology in the lining (to the outer wall can be) coated plastic, performance. Compared with the galvanized pipe, corrosion, rust, scale, smooth smooth, clean and non-toxic, long life and other advantages. According to the test, the service life of inspecting &controlling for three times more than galvanized pipe. Compared with the plastic pipe, has high mechanical strength, high voltage, as well as good heat resistance. Because of the matrix is steel tube, so there is no embrittlement, aging problem. Can be widely used in tap water, gas, chemical products, such as fluid transportation and heating engineering, is an upgraded version of galvanized pipe. Because of its installation method and the traditional basic same galvanized pipe, pipe fittings form also are exactly the same, and can take the place of aluminous model multiple tube on the large diameter water conveying, welcomed by users, has become a pipe market one of the most competitive new products.

Coating steel pipe is in the ERW steel pipe of large diameter spiral welded pipe and coating on the basis of plastic, the most great mouth diameter of 1200 mm, according to the needs of the different coating of polyvinyl chloride (PVC), polyethylene (PE), epoxy resin (EPOZY), and other various plastic coating performance, good adhesion and corrosion resistance is strong, can resist the corrosion of strong acid, strong alkali and other chemical, non-toxic, does not rust, wear resistance, impact resistance, resistance to permeability is strong, the pipe surface is smooth, does not adhere to any material, can reduce the transmission of resistance, improve the efficiency of traffic and transportation, reduce the pressure loss. Coating without solvent, no leakage material, so that it can't be polluted by conveying medium, so as to ensure the purity of fluid and health, in 40 ℃ to + 80 ℃ range can be used cold heat cycles, not aging, not cracking, thus it can be used in cold zone and other harsh environment.

Large-diameter coating steel pipe is widely used in tap water, natural gas, petroleum, chemical industry, medicine, communication, electric power, ocean engineering, etc.
