Zhengzhou outfall steel double-wall corrugated pipe manufacturers enhanced PE spiral corrugated steel pipe belonging to the flexible pipe, the pipe ring stiffness 8-16, the friction coefficient of 0.009, difficult to corrosion, impact compression performance, self-cleaning is not easy scaling, weather is good, effective flow and a variety of hot-melt connection, shrink belt, simple effort. Connections are: hot melt extrusion welding, electric hot-melt en, heat shrink tubing (with) the connection method, clamp connections, the combination connection method. Zhengzhou outfall steel double-wall corrugated pipe manufacturers enhanced PE spiral corrugated steel pipe with a U-shaped steel band PE composite materials to make pipe in without increasing the cost of a substantial increase ring stiffness, in the case of the same weight ratio Pipe, carat pipe strength greatly improved, resolve overloading and other issues, large-diameter steel pipe advantage is more obvious, we now produce pipe diameter from 300mm diameter to diameter 2400mm, ring stiffness remained at 12.5KN / m or more, than the cement pipe and other plastic pipe lighter, and more powerful. Learn from foreign advanced technology and metal-plastic composite pipe PE and the development of a steel melt composite filament winding structure wall pipes. Zhengzhou outfall steel double-wall corrugated pipe manufacturers enhanced PE spiral corrugated steel pipe advantage: unique structure, high resistance to external pressure, impact resistance, has a ring of flexible, smooth wall friction is small, the same inner diameter of the pipe can be larger traffic; socket interfaces, flexible connection, connecting convenient, high reliability, easy to leak. Buried life of five years or more. Light weight, quick construction, reduce costs. Polyethylene belong hydrocarbon polymers, molecular polarity, acid corrosion. Non-toxic, non-corrosive, non-scaling, recyclable. Wide temperature range, -60 ℃ environment does not break in the pipeline, the maximum temperature of the transmission medium is 60 ℃. Integrated project cost and concrete is roughly equal, low operating costs.
