High Quality Donghong coating epoxy resin spiral welding corrugated composite steel pipe

Specifications

Underground coal mine coating (polyethylene or epoxy resin) spiral welding corrugated steel composite pipe is the company with the Chinese Academy of Sciences, Qingdao University of Science & Technology invested a huge sum of money, a new type of steel plastic composite pipe after years of successful development, the performance keeps steel pipe features, and the high performance characteristics of its own (antistatic, flame retardant, high strength). The products have been a number of patent applications. This product is a steel frame with high strength with a special structure as reinforcement, both sides are covered with new company independent research and development of antistatic, flame-retardant modified adhesive, due to enhanced body is covered in the continuous thermoplastic plastics, so, this kind of composite pipe can not only overcome the steel pipe and plastic pipe of each shortcomings, also has the common advantages of steel and plastic pipe, is a revolutionary technology of gas drainage, compressed air pipeline, a pipeline in coal mine, but also solve the petroleum, chemical, pharmaceutical, food, gas and other areas of urgent need of large diameter rigid pipe. Performance characteristics 1.The light weight, long service life, quick install 2.strong corrosion resistance, high pressure bearing, superior mechanical properties 3.Good sealing performance nvenient installation 5.The flame retardant, antistatic performance ating adhesion 7.good self tracer 8.According to user requirements with different coating materials and colors
