Applications:
PE gas pipe can be divided into SDR11 and SDR17.6 by wallthickness: 1, SDR11 series is suitable for natural gas, artificialgas, liquefied petroleum gas (gas); 2, SDR17.6 series is onlysuitable for conveying Natural gas.

Description of the appearance and characteristics:
Yellow pipe, clarinet yellow bar. Executive GB15558.1-2003 BuriedPolyethylene Gas (PE) piping systems Part I: Tube.

Features:
A, High toughness: PE gas pipe requirements of elongation at breakof more than 350%, 500% or more generally, on the managementability to adapt to uneven settlement of the base is very strong,excellent seismic performance;
B, Anti-corrosion: HDPE raw materials and stable performance, inertmaterial, except for a few strong oxidant, can be resistant to theerosion of a variety of chemical media, no electrochemicalcorrosion;
C, Light aging: 2-2.5% with uniform distribution of carbon black inpolyethylene pipe can effectively resist the sun%27s ultravioletrays, in the outdoor open storage or use will not be subjected toultraviolet radiation damage;
D, Green: HDPE water supply pipe processing does not add any heavymetal stabilizers, materials, completely non-toxic, non-foulinglayer, does not breed bacteria, and is gas supply choice of theconstruction of the urban;
E, Transmission capacity, flow resistance: HDPE pipe has a smoothinner surface, the Manning coefficient of 0.009. And non-smoothsurface to ensure adhesion of HDPE pipe has a higher thantraditional pipe transmission capacity, but also reduces thepressure loss and gas transmission pipeline energy consumption.
F, Reliable connectivity: HDPE gas pipe used to melt or fusedconnection, the interface strength higher than the pipe body, theseams will not load due to soil movement or the role of thedisconnected.
G, Economics: The quality of only the steel pipe 1 / 7, glass tube1 / 2, light, and welding process is simple and convenientconstruction, engineering and lower total cost. Under normalworking conditions, PE pipe can be safely used for over 50years.
