Goldstone Reinforced Corrugated Pipe Extrusion Line SRPCP for Sewage & Drainage - 1

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.

STRUCTURE OF SRPCP The structure of the pipe is shown as the diagram. The main pipe body of SRPCP is formed by the HDPE layer (inner and outer layer), and V-shape steel rib which pre-coated with adhesive resin on the surface undertakes the primary support of the pipe; the steel and HDPE is wrapped on the mandrel and bond together to be one integrated spiral-corrugated pipe Goldstone Reinforce Pipe Technology

THE ADVANTAGE OF THE SRPCP PIPE 1) High Ring Stiffness The new composite pipe can provide ring stiffness of SN8, SN12.5 and SN16 generally; even higher stiffness could be made if necessary. The pipe ranges from DN300 mm till DN3000 mm, suitable for various buried storm water system and drainage & sewage water system. Stiffness of SN8 could be provided to whole series of pipes. 2) Saving Material Cost The new reinforced structure pipe can save material cost obviously. When pipe diameter is over DN1000, SRPCP pipe can save nearly 50% of the total materials cost when it is compared with other...
