Steel pipe: PIPE, SAW, LGS; standards: GB/T 9711, PSL1; GB713, Q245R; SH/T 3405. Inspection method: 100% RT; feature: Anti-H2S. What does \"Anti-H2S\" mean in particular?

The default is PE GB/T 9711: GB-T 9711-2011 – Steel pipes for pipeline transportation in the oil and gas industry; PSL1: Product specification level, Grade 1; GB713 Q245R: Standard number of the raw material, grade; SH/T 3405: SH-T 3405-2012 – Dimension series for steel pipes in the petrochemical industry; 100%RT: 100% radiographic inspection of welds; ANTI-H2S: H2S-resistant; 10MM: 10 MM. . . It’s not 10 sisters anyway

PIPE: Pipe; SAW: Submerged Arc Welding; LGS: Longitudinally Welded; BE: Bevel End; GB/T 9711: GB/T 9711 – Steel pipes for pipeline transportation in the oil and gas industry; PSL1: Product specification level 1; GB 713 Q245R: Standard number for raw materials and grade designation; SH/T 3405: SH/T 3405 – Dimension series for steel pipes in the petrochemical industry; 100%RT: 100% radiographic inspection of welds; ANTI-H2S: H2S-resistant (see NACE MR 0175, NACE MR 0103); 10MM: Wall thickness of 10 MM. Based on the description, steel plates made of GB 713 Q245R with ANTI-H2S properties should be used, and they must be manufactured and inspected in accordance with the requirements of GB/T 9711 PSL1. The outer diameter and wall thickness specifications are based on SH/T 3405, with a wall thickness of 10.0 mm. The steel pipe is a straight-seam submerged arc welded steel pipe with a beveled end. 100% RT is required for welds. But there is a problem here: when ANTI-H2S requirements apply, the steel pipe is PSL2 rather than PSL1.
