Inside and outside the plastic coating steel pipe composite pipes are welded steel pipe for the base material, adopt sandblasting chemical pretreatment, double preheating, internal and external coating, curing, post-treatment process and inspecting &controlling. The company independent innovation, successfully developed a new type of tubing. Has its good comprehensive performance, strong corrosion resistance and mechanical, good chemical stability and resistance to water, drag reduction, anti-corrosion, compressive, antibacterial effect, etc. It is generally not the restriction of the transmission medium, the plastic coated layer and steel strong binding force.
Coating material: epoxy resin (EP) is suitable for the working environment, under 80 steel pipe coating has high adhesion force, its coating high hardness, good resistance to impact, and has good resistance to chemical corrosion. Inside and outside the plastic coated pipe is on the inner wall of the steel melts to dissolve a thickness of 0.5 ~ 0.5 mm layer of polyethylene (PE) resin, ethylene – acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and other organic matter and constitute a steel-plastic composite pipe material, it not only has mild steel pipe high strength, easy connection, water resistance and other advantages, also overcomes the steel easy to corrosion, under the influence of water pollution, scale and strength of plastic pipe is not high, poor fire performance shortcomings, design life of 50 years. Main drawback is that when installation shall not be bent, hot working the work such as welding and cutting, cutting the application of the manufacturer is equipped with a non-toxic temperature curing rubber coating base pipe spiral welded pipe, straight seam welded pipe, seamless carbon steel pipe Polyethylene anticorrosive steel pipe is a new kind of inspecting &controlling, its base material by steel tube, and polyethylene coating, epoxy resin coating with excellent mechanical properties and corrosion resistance to aging performance. Widely used in water conservancy, electric power, chemical, oil, and many other industries.
