40 cm wastewater sewer pipe PE spiral corrugated steel pipe reinforced flexible pipeline belonging to this pipe ring stiffness 8-16, the friction coefficient of 0.009, difficult to corrosion, impact compression performance, self-cleaning is not easy scaling, good weather resistance multiple connectivity options, effective flow and hot melt tape, 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. 40 cm wastewater drainage pipes under the premise of using a U-shaped steel with composite PE material, so that the pipe without increasing costs significantly increase ring stiffness, in the case of the same weight ratio Pipe, carat tube greatly improved strength, 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, and lighter than cement pipes and other plastic pipe weight, better performance strong. Learn from foreign advanced technology and metal-plastic composite pipe PE and the development of a steel melt composite filament winding structure wall pipes. Luoyang, Henan Province of China New Materials Technology Co., Ltd. manufactures pipe diameter from 300mm diameter to a diameter of 2400mm, the ring stiffness remained at 12.5KN / m or more, and lighter than cement pipes and other plastic pipe weight, higher performance. 40 cm wastewater pipeline steel enhanced PE spiral corrugated drainage pipes Characteristics: good chemical resistance: topical coating will not be anything contamination and corrosion. Pressure, impact resistance: any foundation has good adaptability. Resistant to aging: the outer wall is black, can resist ultraviolet rays to prevent aging. The economy is good: large diameter lower than the cost of the plastic tube with the specifications. Drainage Circulation superior performance: China New material pipe wall smooth, water resistance. Through water power.
