Using the wire wrapping technology, the polyethylene pipe has been reinforced by high strength steel cord in the middle layer. The composite structure results the pipe materials saving and pressure improving. The new technology can make the HDPE pipe stronger, durable and in the mean time reduce the material cost definitely.
Two layers or four layers of steel cords are wrapped on the polyethylene core pipe. And the adhesive resin is filled in the space between the steel mesh and polyethylene; bond them to form a stable mesh structure. Then the steel reinforced layer is covered by a thin layer of polyethylene.
The SRTP pipe can save Max. 40% material cost for normal water supply pipe in pressure PN10 & PN16.
Pipe diameter is extended to DN1000 mm.
Working pressure is increased to 3.5MPa for steel cord and 15MPa for fibers.
More than 400 sets SRTP pipe extrusion lines were sold in China since year 2002.
About 120 customers in China, included the leading pipe makers.
