The buried polyethylene (PE) pipeline for gas has many excellent performances and is used in the field of gas transportation. The corrosion and joint leakage of steel pipe and cast iron pipe will be thoroughly solved, thus ensuring the safe operation of gas pipe network system. PE gas pipe is made of inert material which can resist erosion of many kinds of chemical medium. PE gas pipe has low friction coefficient, low flow resistance and strong conveying capacity. It is connected by electrothermal melting. The strength of interface is higher than that of pipe body. The elongation at break of high toughness PE is generally more than 500%. PE gas pipe has good seismic resistance and slow crack growth resistance. (SCG), rapid crack propagation (RCP) capability, flexibility and scratch resistance.
The buried polyethylene PE pipeline for gas has strong adaptability to uneven settlement of pipe foundation and strong wear resistance. It can adopt various trenchless methods, which is greatly convenient for construction and installation. The system cost is low, the maintenance cost is low, and the engineering cost can be greatly reduced.
The buried polyethylene pipe for gas is produced and inspected according to the new national standard GB/15558.1-2015 "Buried polyethylene pipe for gas". The polyethylene (PE) gas pipe produced by our company can be divided into four series: SDR11, SDR17, SDR21, SDR26 according to the wall thickness.
Traditional gas pipelines, such as steel pipes and cast iron pipes, the greatest problem is the corrosion and joint leakage that occur generally during the service life. High density polyethylene gas pipeline (HDPE gas pipeline) has many outstanding characteristics, such as corrosion resistance, low temperature resistance, good toughness, safe and reliable joint connection. It has successfully solved the two difficult problems of corrosion and joint leakage of traditional pipeline, and has been widely used in the field of gas transmission and distribution.
