HDPE GAS PIPE PE Polyethylene Gas Pipe

PE gas pipes are processed by blending polyethylene materials. We will thoroughly solve the corrosion and joint leakage problems of steel pipes and cast iron pipes, thereby ensuring the safe operation of the gas pipeline network system. The PE material used for PE gas pipes is an inert material that can withstand the erosion of various chemical media. The friction coefficient of the pipe wall is low, the flow resistance is small, and the conveying capacity is strong. It adopts electric heating fusion connection, and the interface strength is higher than that of the pipe body. The high toughness PE fracture elongation generally exceeds 500%. PE gas pipes have good seismic performance, resistance to slow crack growth (SCG), rapid crack propagation (RCP), flexibility, and scratch resistance.

PE gas pipes have strong adaptability to uneven settlement of pipe foundations, strong wear resistance, and fully comply with the national standard GB/T 15558.1-2015. Multiple non excavation methods can be used, which greatly facilitates construction and installation, has low system cost, low maintenance cost, and can significantly reduce project costs.

Product Application Fields

The buried polyethylene (PE) pipeline for gas is suitable for underground transportation of urban gas pipeline systems with a working temperature of -20-40 ℃ and a maximum allowable working pressure not exceeding 0.7MPa. Suitable types of gas for transportation

1. Natural gas: such as pure natural gas, petroleum associated gas, mine gas, etc

2. Artificial gas: such as coke oven gas, water gas, oil to gas, blast furnace gas, etc;

3. Liquefied petroleum gas

4. Biogas

Product performance:

1. Reliable connection

The polyethylene end pipeline system is connected by electric melting method, and the strength of the joint is higher than that of the pipeline body

2. Good low-temperature impact resistance

Polyethylene has an extremely low low-temperature brittleness temperature and can be safely used within the temperature range of -60-60 ℃. During winter construction, the material has good impact resistance and will not cause pipe brittleness.

3. Good resistance to stress cracking

PE gas pipes have low notch sensitivity, high shear strength, and excellent scratch resistance, as well as outstanding resistance to environmental stress and opening load.

4. Convenient to transport

PE gas pipes are lighter than concrete pipes, galvanized pipes, and copper pipes. They are easy to handle and install, with lower labor and equipment requirements, which means that the installation cost of the project is greatly reduced.

5. Resistant to aging and has a long service life

Polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation.

6. Good wear resistance

The comparative test of wear resistance between PE gas pipes and steel pipes shows that the wear resistance of HDPE pipes is four times that of steel pipes. HDPE pipes have a longer service life and better economy
