application range of plastic-coated steel pipe(1) coal mine system: underground water supply and drainage, fire sprinkler, underground spraying, positive and negative pressure ventilation, and gas drainage, and other pipe networks.(2) heating network water delivery

the anti-corrosion of plastic-coated steel pipes has developed from the earliest inner and outer polyethylene, due to adhesion problems, to inner and outer epoxy, but the outer epoxy layer is not resistant to bumps, and later developed to the third generation of inner epoxy outer

the plastic-coated steel pipe is a coated steel pipe that not only has good corrosion resistance but also has good electrical insulation and low water absorption, which prolongs the service life of the pipe and achieves the purpose of long-term use.advantages of

as we all know, plastic-coated steel pipes can be used not only in the field of water supply and drainage but also in the field of automatic sprinkler fire extinguishing systems, groundwater sewage dredging pipes, central air-conditioning cooling circulating wate

anti-corrosion steel pipe is a common steel pipe. to slow down and prevent the corrosion and depreciation of the steel pipe under the chemical and electrochemical action of internal and external media, or due to the metabolism of microorganisms, it is necessary to do a good job o
