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.

Steel reinforced polyethylene (PE) spiral corrugated pipe is high density polyethylene (PE) as the base, the surface coated with adhesive resin steel strip forming the waveform as the main support structure, and composite with polyethylene material into a whole Double-wall spiral bellows. Jiangsu Xinrong technology manufacturing buried drainage steel reinforced polyethylene (HDPE) spiral corrugated pipe with a continuous steel strip into the approximate shape of the helical rib wrapped in the inner and outer two layers of heat-welded polyethylene, the high steel steel Degree, high strength and polyethylene flexibility, corrosion resistance, wear together.

The advantage is:

  1. Completely reliable ring stiffness: As the elastic modulus ratio of steel and plastic two materials is greater than 200, the weight ratio is greater than 7.85, compared with the pure plastic pipe, steel pipe is easy to enhance the pipe (especially large-diameter pipe) with Rigid and reliable ring stiffness and a relatively high stiffness-to-weight ratio.

2 connection is safe and reliable, can be electric hot melt, heat shrinkable tape, both inside and outside the extrusion welding combination, the connection is solid, pipe leakage.

  1. Steel reinforced polyethylene (HDPE) spiral corrugated pipe steel stiffness, high strength and plastic corrosion resistance, abrasion resistance and flexibility and other excellent combination of not only make the pipe to SN8, SN12.5, SN16 Three levels of ring stiffness, to make up for the larger diameter plastic drain pipe ring stiffness generally only reach the SN8 weaknesses, but also to solve the corrosion resistance of steel.
  2. Steel reinforced spiral bellows due to the use of special materials and processes not only solve the problem of corrosion of steel plate also solved the adhesion of steel and PE materials, the life of the pipe and pure plastic pipe, guaranteed more than 50 years.
