HDPE Gas Pipe

Jiashang Pipeline Industry
Product introduction
Product specification

    HDPE gas pipe is made of special polyethylene as raw material by one-time extrusion in a plastic e-

xtruder. It is suitable for all kinds of industrial grade water gas transportation. A good pipeline should

 not only have good economy, but also have a series of advantages such as stable and reliable interfa-

ce, material impact resistance, cracking resistance, aging resistance, corrosion resistance and so on.

 Compared with traditional pipes, HDPE pipeline system has the following advantages:

    1.Resistance to chemical corrosion such as natural gas, liquefied gas and artificial gas, without seco-

ndary corrosion protection;

    2.Light weight, high strength and strong wear resistance.

    3.Beautiful appearance, smooth inner and outer walls, low fluid friction and soft color;

    4.Hot-melt butt welding and socket welding are adopted, which are easy to install, good air tight-

ness, safe and reliable.

    5.Long service life, pipeline system under normal service life of more than 50 years, low depreciation;

    6.Pipes can be coiled, easy to transport and low cost.

    7.Good flexibility, shock resistance and impact resistance.

    8.Waste materials can be recycled and will not pollute the environment.
