Enhanced PE spiral corrugated steel pipe is a PE and steel melting complex structure wall pipe. Wall structure consists of three levels of constitutive layers: the inner layer is a solid wall PE inner tube connected to the inner tube is wound-composite steel split ring corrugated steel inverted "U" shaped reinforcement, coated corrugated steel reinforcing in In vitro and steel reinforced composite has the same outer body wave PE. 1, public works: for drainage, sewage. 2, residential areas, used as rainwater drainage. 3, farmland irrigation water, Pai Road. 4, sewage treatment plants, landfill drainage conveyance. 5, highway embedded pipes. 6, chemical ventilation pipe, expanding the mountain for fluid delivery. Quality of light: the lightest structural wall pipe. Site installation without lifting devices, saving time and costs. High intensity: As a result of steel structure, greatly improving the pipe ring stiffness, can reach SN24. It can greatly improve the soil to withstand vehicle loads. Steel structure to make the pipe ring stiffness remains constant during the life. Easy installation: a single pipe length, thus reducing joints, install faster. Plastic pipe connection or electric hot-melt extrusion welding with welding, solid, reliable, simple and fast. You can ditch the length of the connection as required, artificial into the trench, the trench section can be reduced, saving the cost of earthworks. Length can be cut on site and simple. Good flexibility: the smaller foundation settlement can withstand without damage to the pipe. Installation can be reduced to some curved connecting wells. Transportation and easy handling: tubes of different diameters and can be nested to reduce transportation costs. Rugged steel liner structure allows the pipe to withstand shocks during transport. Versatile: good features and no penetration of the pipe link a way that is urban municipal engineering sewage, storm sewer pipe of choice. Engage in chemical corrosion, it is buried in the acidic or alkaline soil environment ideal pipe. Excellent corrosion resistance, can transport various chemical solution type sewage. Good high wear resistance, can be used for hydraulic transport of mine tailings, plant.
