Steel Reinforced Corrugated Pipe Technology

Compared with the traditional steel pipe and concrete pipe, the plastic pipe shows the big advantages, such as anti-corrosive, less leakage, light weight and easy installation. But the serious disadvantage of the plastic pipe is the low elastic modulus, e.g. polyethylene EP value is about 800 Mpa. While the elastic modulus of carbon steel is about 190,000 Mpa, which is almost 200 times higher than polyethylene. As well, the price of steel is half of the polyethylene. So if we can combine the advantages of steel and plastic into a composite pipe, that will get a perfect large diameter pipe with high stiffness and less cost.

Since 2003, Goldstone Orient company has developed the innovated conception of steel reinforced corrugated pipe (SRPCP) with its owned technology. With the powerful steel reinforced corrugated rib, the pipe stiffness was raised to SN16 or higher while the pipe diameter can reach maximum DN3000. Because of its obvious advantages on material cost saving and stiffness, during the last dozen years of time, SRPCP was rapidly developed in China, became the winner in competition with other kinds of structure wall pipe.
