Guorun's Steel Reinforced PE Corrugated pipe is better engineered for a more durable joint and long-lasting performance. It’s made from HDPE with steel strip reinforced inside.This structure make it have extremely high ring stiffness, which enable it to withstand huge surrounding pressure.
It is expected to significantly exceed 100 years’ service life.
Between the outer HDPE and the inner steel strip, there is a special adhesive resin to attach these two layer with greatest force, to prevent the layers from separating.
Light weight compared with steel pipe or concrete pipe, easy to install.
Saves money on installation costs due to its long length and easy transport.
Guorun's Steel Reinforced PE Corrugate pipe is suitable for use in gravity flow drainage in residential, commercial, recreational, agricultural and industrial application.
Guorun's Corrugated pipe in 4-9 inch diameters meets AASHTO M252 and ASTM F2648.
In 10-60 inch diameters, it meets AAS-HTO M294 and ASTM F2306 and ASTM F2648. It comes in 20 or 40 feet lengths.
Its superior strength to weight ratio gives it as much as SN16 Ring Stiffness. Its Peeling Strength (20±5℃),N/cm ≥70 and TIR is no less than 10%.
Its creep rate is ≤2 . Most importantly,Guorun's Corrugated pipe’ welding joint has a tensile strength of no less than 1460.
