SRCP employs a multilayer wall construction consisting of inner and outer polyethylene layers and an omega-shape steel profile bonded to the two polyethylene layers by an adhesive. Such construction maintains the key properties of polyethylene pipes (low coefficient of friction, chemical resistance, lightweight, etc.) while also benefitting from the structural properties of steel (high stiffness). Compared to plastic pipe, the use of steel in SRCP pipe provides higher resistance to external loads but lower consumption in raw materials. Using the spiral wound pipe processing method combined with steel reinforcing technology, allows large inner diameter SRCP pipe to be produced from 300 mm (12 inch) up to 3000 mm (125 inch) with pipe ring stiffness ranges typically from SN8 (63Psi) to SN16 (158Psi), or even higher.
There are now many industry standards for SRCP that have been issued by different countries and organizations including ASTM F 2435-15,CJ_T 225-2011,UNI 11434 ITA,CSA B182.14-15, SII458,etc.
