HDPE gas pipeline

HDPE gas pipe introduction

PE gas pipe is a high-performance pipe made of polyethylene as the main body and is widely used in urban gas delivery systems. The pipe adopts advanced extrusion molding process and has good pressure resistance, impact resistance and corrosion resistance. Its inner wall is smooth and the fluid resistance is small, which can effectively improve the gas transportation efficiency. PE gas pipes use hot-melt connection, which is convenient and quick to construct. The connections have high strength and good reliability. They are suitable for laying gas pipelines in various complex terrains and climate conditions.

Product advantages : PE gas pipes stand out in the chemical and energy, mineral and chemical products industries with their excellent performance. First of all, it has strong corrosion resistance and anti-aging properties, and can be used for a long time in harsh environments without damage. Secondly, PE gas pipes have good flexibility and can adapt to various terrain changes, reducing installation difficulty and cost. In addition, the pipeline is green, non-toxic and tasteless, meets the environmental protection requirements of modern society and is conducive to sustainable development.

 Features of buried polyethylene PE pipes 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 caused by 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, and its elongation at break generally exceeds 500% . It has a 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. Used for non-grooving construction, the direction of PE gas pipelines can be easily changed according to 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 avoids the defects of aging and corrosion of exposed heating wires, and the inner wall of the pipe is smooth and flat, which is easy to install.
   7. Good resistance to rapid crack transmission. Rapid cracking of the pipeline refers to the fact 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 has not been found in actual use.
   8. Long service life, up to more than 50 years.
