Product introduction
Product Overview
76~660mm API 5L PSL2 ERW & HFW medium pressure natural gas pipeline tube is high-grade line pipe specially designed for onshore medium-pressure natural gas distribution, city gas network and gas gathering pipeline projects. Manufactured by mature ERW electric resistance welding and HFW high-frequency induction welding technology, this PSL2 level pipe meets strict API Spec 5L and ISO 3183 specifications, with mandatory Charpy impact toughness test, full seam UT non-destructive inspection and precise chemical composition control. It features uniform weld structure, stable yield/tensile ratio, excellent low-temperature toughness and reliable air tightness, suitable for long-distance buried and overhead medium-pressure natural gas transportation. Covering complete outer diameter range of 76mm to 660mm, the pipe supports customized wall thickness, fixed cutting and anti-corrosion coating like 3LPE, FBE. It is widely adopted for municipal natural gas trunk lines, industrial gas supply pipelines and gas station connecting pipelines, the preferred welded line pipe for global medium-pressure gas transmission projects.

Production Technology & Natural Gas Transmission Performance
This API 5L PSL2 gas pipeline tube adopts ERW/HFW dual high-frequency welding forming process. The steel coil is continuously cold formed and welded, followed by weld seam local heat treatment and stress relief, eliminating welding residual stress and ensuring weld toughness matches base metal. As PSL2 grade line pipe, it has stricter control on chemical composition, carbon equivalent and yield-to-tensile ratio, with mandatory Charpy impact test for pipe body, weld and HAZ to guarantee low-temperature anti-fracture performance under seasonal temperature fluctuation.
Every pipe undergoes full-length weld ultrasonic non-destructive testing and 100% hydrostatic pressure test to eliminate welding defects and hidden leakage risks, fully meeting the safety requirements of medium-pressure natural gas transportation. Optional FBE or 3LPE external anti-corrosion coating provides excellent resistance against soil corrosion, groundwater and microbial corrosion for buried gas pipelines. The pipe maintains stable mechanical performance under long-term cyclic gas pressure load, avoiding brittle fracture and gas leakage, suitable for urban gas network, gas gathering and industrial medium-pressure gas delivery projects with strict safety acceptance standards.
