At present the composite pipe has been widely used in many applications and various steel-plastic composite pipes have been developed. The Steel Reinforced Polyethylene Spiral Corrugated Pipe (SRPCP pipe) is one of the best solutions among those pipes, which has been researched by our company with Chinese patent.

The diameter of the pipe is from 300 mm (12 inch) up to 3200 mm (126 inch). The obvious advantage of the new composite pipe is the high stiffness and low cost if compared with the universal buried plastic sewage pipe. The ring stiffness reached SN8 to SN16, which is a surprise value for other plastic pipes. This pipe meets ASTM 2435-12 standard and Israel, Italian standard, Chinese national standard etc.It is a great technical innovation to use the steel-plastic composite construction instead of the single material (plastic) for sewage and drain pipe system. The new composed structure brings many advantages like higher stiffness, less weight, low cost, large diameter, etc. The diameter of the pipe is from 300 mm (12 inch) up to 3200 mm (126 inch).
