advantages of plastic-coated steel pipe1. hygienic, non-toxic, no fouling, no breeding of microorganisms, ensuring fluid quality2. resistant to chemicals, soil and marine organisms, cathodic disbonding3. the installation process is mature, convenient, and fas

1. it should be implemented by cecs125:2001 of "technical regulations for building water supply plastic-coated composite pipe pipeline engineering".2. the following construction equipment should be used for plastic-coated steel pipes:(1) the cutting shoul

plastic-coated steel pipesplastic-coated steel pipes, also known as plastic-coated steel pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes, and use pe (modified polyethylene) for hot dipping or ep (epoxy resin) as the

plastic-coated steel pipe not only has the advantages of high strength, easy connection, and water impact resistance, but also overcomes the shortcomings of steel pipes such as easy corrosion, pollution, scaling, low-strength plastic pipes, and poor fire performance. the design l

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
