Liansu is engaged in the supply of high quality pe gas pipes according to the ISO standards. Some of its wide applications are in gas transportation, water supply, sewage discharge, agricultural irrigation, oil field, mines, chemical industry and telecommunication areas. PE gas pipes has become the second mostly used plastic pipe in the world. Some of the classifications of PE pipes are:
These pipe are generally classified according to the characteristics of polyethylene materials.

* By Density: Low density PE pipe, high density PE pipe and middle density PE pipe.
* By Hydrostatic strength: It is basically classified into five grades: PE 32, PE 40, PE 63, PE 80, PE 100 according to the long term hydrostatic strength.
* By Use:
PE pipe for water supply and PE gas pipes.


Some of the characteristics of PE gas pipes are:
PE pipe has good corrosion resistance and is leak proof on joint and comparing with traditional pipes.

* Resistance to corrosion.
* Leak proof on joint.
* Great flexibility.
* Long lifetime.
* Easy recycling.
* High toughness with elongation at break and has great settlement resistance.
* Good fast crack propagation resistance.

Application areas of gas pipe:
Buried PE gas pipes is suitable for gas transportation on condition that working temperature is among -200 c—400 c and the working pressure should not be more than 0.4MPa.
