The high mechanical strength steel-plastic composite pipe has the same excellent mechanical strength as the hot-dip galvanized steel pipe, and has a strong endurance to the impact, bending, pressure and strength. The temperature requirements of composite pipes are getting higher and higher. The best temperature for producing steel pipes is to find the right temperature, as long as the functions of the steel pipes produced in this way are good cable roller.
The improvement of the technology of plastic composite steel pipe manufacturers guarantees the quality. On the million-kilometer long road that Feisu has taken, more users will realize no major repairs for one million kilometers. This is the high-quality strength of Feisu technology products. certificate. Good insulation performance and long service life? Because the rigid polyurethane foam layer is tightly bonded to the outer skin of the steel pipe, it can block the infiltration of air and water, which can play a good role. Introduction to the diameter of plastic coated steel pipe The structure of the steel pipe is: polyethylene three-layer protective layer, also known as three-layer. The tube not only has extremely high quality such as higher flame retardancy, higher Vicat temperature, higher volume resistivity, higher strength, and smaller coefficient.
The unique wall thickness design of steel pipes includes the inner plastic pipe wall thickness and the outer welded pipe wall thickness, which determines its series of technical characteristics: pipe cutting pipe cutting should use metal saws, large diameter pipes should use sawing machines, when using entangled cutting, the speed should not be more than the. The base pipe of the plastic-coated pipe is a longitudinally welded steel pipe which shall meet the requirements for the base pipe; the base pipe is a seam submerged arc welded steel pipe shall conform to the requirements for the base pipe; the base pipe shall be a seamless steel pipe shall conform to the requirements for the base pipe Claim.
