Gas PE pipe

Introduction to PE gas pipes
PE gas pipes use gas polyethylene pipes, which have many excellent properties and are applied in the field of gas transportation. We will thoroughly solve the corrosion and joint leakage problems of steel pipes and cast iron pipes, thereby ensuring the safe operation of the gas pipeline network system. The PE material used for PE gas pipes is an inert material that can withstand the erosion of various chemical media. The friction coefficient of the pipe wall is low, the flow resistance is small, and the conveying capacity is strong. It adopts electric heating fusion connection, and the interface strength is higher than that of the pipe body. The high toughness PE fracture elongation generally exceeds 500%. PE gas pipes have good seismic performance, resistance to slow crack growth (SCG), rapid crack propagation (RCP), flexibility, and scratch resistance.
PE gas pipes have strong adaptability to uneven settlement of pipe foundations, strong wear resistance, and can be used in various non excavation methods, which greatly facilitates construction and installation. The system cost is low, the maintenance cost is low, and the engineering cost can be significantly reduced.

PE gas pipe execution standard
PE gas pipes comply with the national GB15558.1-2003 standard.
Appearance of PE gas pipe: At least 3 yellow strips should be extruded on the black pipe, and the color strips should be evenly distributed along the circumference of the pipe.

－Shandong Kaiyuan has multiple PE gas pipe production lines, which can produce 24 specifications of PE gas pipe materials in two grades: PE80 and PE100mm.

－Application of PE gas pipes

Polyethylene (PE) gas pipelines have been successfully widely used in the field of gas transmission and distribution, and are favored by many gas industry households due to their long-term service life, excellent corrosion resistance, reliable connection and safety performance, as well as low construction and maintenance costs and many other advantages. According to the different grades of raw materials, polyethylene gas pipes are divided into two grades: PE80 and PE100; According to the standard size ratio, it is divided into two series: SDR11 and SDR17.6. The SDR11 series is suitable for the transmission and distribution of various gaseous media such as natural gas, liquefied petroleum gas (gas), and artificial coal gas, while the SDR17.6 series is suitable for the transmission and distribution of natural gas.
