Anti-aging HDPE double wall winding pipe
1.Corrosion resistance, impact resistance
2.Service life of up to 50 years
3.HDPE can be recycled is a green product
<
1.Safeand reliable plastic pipe ring stiffness compared with the pure, easy to enhance the steel pipe, especially large-diameter pipe with a sufficient degree of safety and reliability of the ring of steel
2.Smooth wall, low flow resistance than cement pipes 20 to 30% polyethylene (PE) pipe wall is smooth, low friction coefficient, and sediment accumulation in the pipeline is not easy to produce, the friction is almost constant after long-term use
3.Flexible or no leakage (electric welding, butt welding) connection, good sealing performance and environmental performance of two kinds of sealed connection can be a simple manual tools, no machinery, is very simple and quick to achieve reliable leak-free
4.Corrosion life of more than 50 high-density polyethylene (PE) pipe service life of up to five years
5.Light weight, small joints, no large-scale equipment, light weight and easy installation of the laying, installation does not require a large lifting equipment. Axial flexibility is good, laying on the bottom of the trench when the flatness, firmness requirements are lower, caused by improper installation can withstand the stress of the ability of non-normal
