Why use PE pipe as gas pipe

Why use PE pipe as gas pipe

Using polyethylene resin as the main raw material, the buried polyethylene pipe for gas after extrusion molding, referred to as PE gas pipe.
What color is the PE gas pipeline?
       The color of the tube is yellow or black, and there must be a bold yellow color bar on the black tube.
What are the product specifications of PE gas pipes?
       Standard size ratio SDR17.6 φ20 ～ φ630 0.2MPa
       Standard size ratio SDR11 φ20 ～ φ630 0.4MPa
Why is the SDR11 series suitable for conveying artificial gas and liquefied petroleum gas?
       According to ISO4437: 1988 (E) A1: "If in contact with liquid hydrocarbons (condensate, odorant or aromatic hydrocarbons) during the entire use of the pipe, the SDR11 (S5) series of pipes is recommended for 50-year life. China's artificial coal gas and liquefied petroleum gas generally contain liquid hydrocarbons, so SDR11 is applicable to the transportation of natural gas, artificial gas and liquefied petroleum gas.
What is the maximum allowable working pressure of the two series of pipes?
       At 20 ℃, the maximum allowable working pressure of SDR11 series is 0.4MPa, and the maximum allowable working pressure of SDR17.6 series is 0.2MPa.

What are the advantages of PE gas pipes?
       1) High strength, excellent stress cracking resistance and creep resistance;
       2) Good toughness and flexibility, strong adaptability to uneven foundation and misalignment, and can withstand harsh environments such as earthquakes and typhoons;
       3) Has good weather resistance (including UV resistance) and long-term thermal stability;
       4) Corrosion resistance, long service life, suitable for transportation of natural gas, liquefied petroleum gas and coal gas;
       5) Smooth inner wall, large circulation capacity, gas flow rate can reach 20m / s, saving operating costs;
       6) Good wear resistance and wear resistance;
       7) Good resistance to low temperature impact, can be safely used in the temperature range of -20-40 degrees, and construction in winter is not affected;
       8) The hot melt (or electric melt) connection is convenient and reliable, and the construction and maintenance are simple (the gas can be kept in between);
       9) It is fully suitable for traditional excavation construction methods and brand-new trenchless technologies such as pipe jacking, directional drilling, liner pipe, split pipe, and submersion;

       10) Polyethylene raw materials contain only two elements, carbon and hydrogen, which are harmless to the environment and are environmentally friendly.If you want to know more about it please do not hesitate to contact me. WhatsApp:+86-15966835076
