HDPE gas pipe

PE gas pipe was awarded the high-tech products.

Applications of HDPE gas pipe:
PE gas pipe can be divided into SDR11 and SDR17.6 by wall thickness: 1, SDR11 series is suitable for natural gas, artificial gas, liquefied petroleum gas (gas); 2, SDR17.6 series is only suitable for conveying Natural gas.

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

Features of HDPE gas pipe :
A, high toughness: PE gas pipe requirements of elongation at break of more than 350%, 500% or more generally, on the management ability to adapt to uneven settlement of the base is very strong, excellent seismic performance;
B, anti-corrosion: HDPE raw materials and stable performance, inert material, except for a few strong oxidant, can be resistant to the erosion of a variety of chemical media, no electrochemical corrosion;
C, light aging: 2-2.5% with uniform distribution of carbon black in polyethylene pipe can effectively resist the sun%27s ultraviolet rays, in the outdoor open storage or use will not be subjected to ultraviolet radiation damage;
D, green: HDPE water supply pipe processing does not add any heavy metal stabilizers, materials, completely non-toxic, non-fouling layer, does not breed bacteria, and is gas supply choice of the construction of the urban;
E, transmission capacity, flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. And non-smooth surface to ensure adhesion of HDPE pipe has a higher than traditional pipe transmission capacity, but also reduces the pressure loss and gas transmission pipeline energy consumption.
F, reliable connectivity: HDPE gas pipe used to melt or fused connection, the interface strength higher than the pipe body, the seams will not load due to soil movement or the role of the disconnected.
G, economics: the quality of only the steel pipe 1 / 7, glass tube 1 / 2, light, and welding process is simple and convenient construction, engineering and lower total cost. Under normal working conditions, PE pipe can be safely used for over 50 years.
