Dear expert, could you please explain what this material description means?

It’s an abbreviation for pipeline components; search on Baidu

Based on the description provided in the material, the following can be inferred: PIPE – refers to pipes; SAW – is an abbreviation for Submerged Arc Welding, indicating that the pipe manufacturing process involves submerged arc welding; LGS – is an unknown abbreviation; PE – is an abbreviation for Polyethylene, meaning that polyethylene material is used in the production of these pipes; GB/T 9711 PSL1 L245 – refers to the standard number/specification code, indicating that these pipes meet the PSL1 grade requirements of China’s GB/T 9711 standard, with a material grade of L245; WQF 0.85 – has an unknown meaning; specific background information is required to understand its significance; SH/T 3405 – is another standard number/specification code, indicating that these pipes comply with China’s petroleum industry standards as specified in SH/T 3405; STD – is an abbreviation for Standard, meaning that these pipes meet the requirements of relevant standards. In summary, the product described in this material is a type of pipe manufactured using submerged arc welding, with polyethylene as the main material. It meets the PSL1 L245 grade requirements of China’s GB/T 9711 standard, as well as the requirements of China’s petroleum industry standards outlined in SH/T 3405. The specific meaning of “WQF 0.85” requires additional information to explain. .

Pipe, submerged arc welding, straight weld seam, flat end, specification grade 1, material L245, ASME B31.1 welding quality factor 0.85, STD standard pipe

PE=Plain End, flat end without bevel: L

Page 817 of the standard specification “Selection and Engineering Application of Pipeline Materials” provides the following explanation: PIPE, SAW, LGS, PE, GB/T 9711 PSL1 L245, WQF 0.85, SH/T 3405, STD – these terms refer to pipes, Submerged Arc Welding, straight welds, flat ends, level 1 according to the standards, material grade L245, a welding quality factor of 0.85 as per ASME B31.1, and STD-standard wall thickness pipes of grade SCH40 (for small diameters) or SCH20 (for large diameters). In detail: PIPE refers to pipes; SAW is an abbreviation for Submerged Arc Welding, indicating that the welding process used is submerged arc welding; LGS denotes straight welds; PE means flat ends; GB/T 9711 PSL1 L245 refers to the standard number/specification code, indicating that the pipeline product meets the PSL1 requirements of China’s GB/T 9711 standard, with material grade L245; WQF 0.85 represents the welding quality factor of 0.85 as per ASME B31.1; SH/T 3405 is another standard number/specification code, indicating that the pipeline product complies with China’s petroleum industry standard SH/T 3405; STD refers to STD-standard wall thickness pipes of grade SCH40 (for small diameters) or SCH20 (for large diameters)
