High-density polyethylene pipe is valued by the pipeline industry for its excellent chemical properties, toughness, wear resistance, low cost and installation cost. It is the second largest plastic pipe material after polyvinyl chloride.we are twin wall pipe suppliers.
The high-density polyethylene pipe (HDPE) double-wall corrugated pipe is a pipe material which is material-saving, high in rigidity, excellent in bending property, and has a corrugated outer wall and a smooth inner wall. The double-walled pipe can save 40% of the ordinary pipe of the same strength and the same strength, and has the characteristics of high impact resistance and high compression resistance, and is developing rapidly. In Europe and the United States, HDPE double-wall corrugated pipes have replaced steel pipes, cast iron pipes, cement pipes, asbestos pipes and ordinary plastic pipes in a considerable range, and are widely used as drainage pipes, sewage pipes, underground cable pipes and agricultural drainage pipes.
Double wall tube features:
13:1 shrinkage ratio, suitable for insulation and sealing of irregular shapes;
2 medium wall thickness, while maintaining softness, improve the mechanical protection strength;
3 glue layer can bond plastic, rubber, metal;
4 initial shrinkage temperature of 70 ° C, full shrinkage temperature of 125 ° C;
5 inner rubber layer melting temperature: 70 ° C -100 ° C;
6 working temperature range: -40 ° C ~ 125 ° C
