SDR11 and SDR17 are the preferred series.

SDR21 and SDR26 are commonly used for repairmen of trenchless gas pipeline


Long service life: HDPE pipelines can be safely used for more than 50 years in normal working conditions


High toughness: The break elongation of HDPE gas pipelines exceeds 350%, generally can reach more than 500%. It has strong adaptability to uneven settlement of pipe foundation and excellent seismic performance.


Corrosion resistance: HDPE raw material has stable performance as an inert material. It can withstand a variety of chemical media, except for a few strong oxidants, without electrochemical corrosion.


Green and environmental protection: HDPE pipeline processing does not add heavy metal salt stabilizer, the material is non-toxic, no fouling layer, no bacteria, and is the first choice for urban gas supply construction.


Strong impact resistance: HDPE pipe has good toughness and high impact strength. Heavy objects directly press through the pipe and will not cause pipe rupture;


Good resistance to rapid crack propagation and resistance to slow crack growth


Reliable connection performance: HDPE Pipes are hot-melt or fused, the strength of the interface is higher than that of the pipe body, and the joints are not broken due to soil movement or load.

Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the comprehensive construction cost is low.
