Enhanced PE spiral corrugated steel pipe is to learn from foreign advanced technology and the development of a new type of structural wall composite pipe. Structural wall pipe forming a spiral wound high-strength steel to enhance the body, wrapped in a synchronized hot melt molding of high density polyethylene PE matrix, through a unique manufacturing process made of. Plastic pipe tubing both flexibility and corrosion resistance, but also with a metal pipe high rigidity and high strength. Product implementation of CJ / T 225-2011 "underground drainage steel reinforced polyethylene (PE) spiral corrugated tube" standard. Features 1. rigidity and impact: Since the pipe intermediate layer using the "U" shaped steel belt reinforcements with high rigidity. 2. The unique structure, complex solid and reliable: special pretreatment of the strip surface, so that PE and strip joint surface with a strong adhesive strength. 3. The construction convenient, fast: pipeline construction requirements for basic processing low from seasonal temperature limits. Product is light weight, easy construction. 4. Connect diverse, reliable: the pipeline can be connected to the heat-shrinkable band, fused with the connection, PE torch out of a variety of connections such as welding, effectively ensure the bonding strength. 5. excellent liquidity drain: pipe wall is smooth, low friction damping, fast drainage, through hydro power, flow, under the same conditions than the concrete pipe output increased by more than 40 percent water. 6. superior wear resistance: the more steel, cast iron pipes, cement pipes and other pipes resistant to wear. 7. corrosion resistance, long life: Pipe acid and organic solvents, resistant to water, wastewater chemicals and soil organic matter decay corrosion. 8. normal use, the pipe life of more than 50 years. Product Applications 1. municipal underground drainage and sewage pipes. 2. Industrial drainage and sewage pipes. 3. seawater, rainwater pipes. 4. agricultural irrigation and drainage pipes. 5. WATER drainage, flood discharge pipe. 6. mine drainage, ventilation pipes.
