PE gas pipeline

Features of buried polyethylene PE pipeline for gas:

1. Corrosion resistance. Polyethylene is an inert 

material. Except for a few strong oxidants, it can 

resist the erosion of various chemical media, has 

no electrochemical corrosion, and does not require

an anti-corrosion layer.

2. No leakage. PE gas pipelines are mainly connected

by fusion (hot-melt connection or electric fusion

connection). Compared with rubber ring joints or 

other mechanical joints, there is no risk of leakage

due to joint distortion.

3. Good scratch resistance. It can effectively resist

the stress concentration of materials caused by

scratches, greatly reducing the possibility of pipeline 

damage.

4. High toughness. PE gas pipe is a high-toughness pipe

material with a breaking elongation generally exceeding 500%. 

It has a very strong adaptability to uneven settlement of

the pipe base. It is also a pipe with excellent seismic 

performance.

5. Excellent flexibility. The flexibility of polyethylene 

allows PE gas pipes to be coiled. For non-grooving construction,

the direction of PE gas pipelines can be easily changed 

to meet the requirements of the construction method.

6. Advanced electric fusion pipe fittings structure. 

The non-exposed spiral heating wire ensures uniform heat 

conduction in the welding area and effectively prevents 

short circuits when the pipe is inserted. At the same time, 

it can avoid the defects of aging and corrosion of exposed 

heating wires and the inner wall of the pipe is very smooth 

and flat, which is easy to install.

7. Good resistance to rapid crack transmission. Rapid 

cracking of the pipeline means that when the pipeline 

accidentally cracks, the crack grows at a speed of several

hundred meters per second, instantly causing a major 

accident of tens of meters or even thousands of meters 

of pipeline rupture. Rapid cracking of polyethylene gas 

pipes have not been found in actual use.

8. Long service life, it's up to more than 50 years.
