API 5L PSL1 X52 line pipe

Product Introduction

　　API 5L PSL1 X52 (L360) is a mainstream medium-strength carbon steel line pipe tailored for petroleum and natural gas pipeline transportation systems. As one of the core grades in the full API 5L series covering Grade B, X42, X46, X52, X56, X60, X65 and X70, X52 line pipe is available in both PSL1 and PSL2 specification levels to match different project safety standards.

　　We supply full-range API 5L PSL1 X52 line pipes in multiple manufacturing types, including seamless (SMLS), ERW, HFW, LFW and SAW submerged arc welded pipes. Featuring stable mechanical performance, excellent crack propagation resistance and good weldability, coated X52 PSL1 pipes are hot-selling products widely adopted for conventional oil, gas, water and liquid transmission projects worldwide.
