Is the plastic steel composite pipe lined with plastic galvanized steel pipe?
By pretreatment, preheating, internal coating, leveling, postprocessing technology made in water supply galvanized plastic composite pipe, is the upgrading of traditional galvanized pipe, steel plastic composite pipe with threaded connection.Plastic lining composite steel pipe: pipe to polyethylene plastic pipe lining in the outer layer, so the manufacturing cost is reduced, and ensure that the thickness to ensure the strength, the installation of plastic lining composite steel pipe with polypropylene PP-R pipe cost almost close to the aluminum-plastic composite pipe, stainless steel pipe is much lower than pure and pure copper.
Because the steel strip of the middle layer of the pipe is closed, the steel plastic pipe has the function of oxygen resistance, and can be directly used for the direct drinking water project, and the inner and outer layers are made of plastic materials, and have very good corrosion resistance.Because of its excellent performance, the use of steel plastic composite pipe is very extensive, oil and gas transmission, industrial and mining pipes, drinking water pipes, drainage pipes, and so on, can be seen in various fields of this kind of pipe.
Steel plastic composite pipe, a new kind of composite pipe material, is called plastic steel pipe in many places. Steel is an iron material; plastic refers to plastics, plastic steel composite pipes in the plastic is generally high-density polyethylene.The steel plastic composite pipe has many classifications, and can be classified according to the structure of the pipe: steel reinforced plastic steel composite pipe, seamless steel pipe reinforced steel plastic composite pipe, hole net steel tape, plastic steel composite pipe and steel wire frame plastic steel composite pipe.At present, the market is the most popular steel reinforced steel plastic composite pipe, that is we often say that the steel plastic composite pressure pipe, the pipe layer and the middle layer is the steel strip of high carbon steel by curling forming butt welding, inner and outer layer were high density polyethylene.
NoSteel plastic composite pipe: the product is made of seamless steel pipe and welded steel tube. The inner wall is painted with high adhesion, anticorrosion, food grade sanitary powder coated with polyethylene or epoxy resin coating.
