Traditional gas pipelines such as steel pipes and cast iron pipes have the biggest problems of corrosion and joint leakage that occur during the service life.Polyethylene(HDPE) pipe has many excellent characteristics, corrosion resistance, low temperature resistance, good toughness, and safe and reliable joint connection.

HDPE gas pipes are suitable for the transportation of various gas media such as natural gas, liquefied petroleum gas (gaseous) and artificial gas.

Apppication for HDPE gas pipelines

1. Long distance gas pipeline
2. Town gas transmission and distribution pipeline
3. Industrial and enterprise gas pipeline
4. Underground gas pipeline
5. Overhead gas pipeline
6. Submarine gas pipeline

HDPE gas pipes construction precautions

1. The various connections of the pipeline should be equipped with corresponding special connection tools. When connecting, open flame heating and water cooling are strictly prohibited.
2. Pipe, pipe fittings and pipe fittings can be connected by hot melt connection - hot melt butt joint, hot melt socket connection, hot melt saddle connection
3. Electrofusion connection - electrofusion socket connection, electrofusion saddle connection
4. Mechanical connection - locking type and non-locking type socket connection, flange connection, steel-plastic transition connection (mainly with the non- Polyethylene pipe)

HDPE pipes for gas is a replacement for traditional steel pipes and PVC gas pipes.

The reason why HDPE gas pipelines are classified according to the pressure of gas transmission is because the tightness of gas pipelines has strict requirements compared with other pipelines. If there is gas leakage, it may cause fire, explosion, poisoning or other accidents. The higher of the pressure in the gas pipeline, the greater the possibility and risk of cracking the pipe joint or cracking the pipe itself. When the pressure of the gas in the pipeline is different, the requirements for the material, installation quality, inspection standard and operation management of the pipeline are also different.

Due to the particularity of gas pipelines, we set up strict standards on production and inspection. Our products are not only economy, but also have many advantages of low temperature, impact resistance, crack resistance, chemical resistance, anti-age, long life span and so on.

1. Reliable connection
2. Low temperature impact resistance
3. Good resistance to stress cracking
4. Good chemical resistance
5. Anti-aging, long service life
