The API 5L is a specification covers both seamless as well as API 5L Grade B Pipes, API 5L Gr.B Carbon Steel Line Pipes Welded Pipes from grades ranging between X42 up to X80. Typically associated with applications like transportation of gas, water, and oil, the API 5L Grade B Seamless Pipes, API 5L specified pipes are usually found in the hydrocarbon petroleum industry along with the oil and natural gas industry. These API 5L Grade B PSL1 Material seamless and welded pipes often are produced in a size range of 1 inch to 30 inches with the schedule chart as follows - SCH 40, SCH STD, SCH 80, SCH XXS, SCH XS, SCH 20, SCH 160.
API 5L Grade B Pipes
API 5L Grade B Erw Pipes
Difference between PSL1 and PSL2 Pipes
API 5L PSL1 Grade B Seamless Pipes is considered to be a rather loose standard quality for line pipes. On the other hand, PSL 2 not only contains an additional testing requirement, but the level also requires much stricter chemical physicals. Moreover, the API 5L PSL2 Grade B Line Pipes Welded Pipes has a different ceiling limits of mechanical properties, as opposed to PSL 1. PSL 2 specified pipess also require Charpy impact testing conditions. API 5L Grade B Erw Pipes, NACE MR0175 is a standard pertaining to the Petroleum and natural gas industries. Which means this standard deals with components to be used in hydrogen sulphide containing environments observed during oil and gas production. The NACE MR0175 ERW Pipes was issued as a recommendation to the inception of the limits of H2S or hydrogen sulphide where caution is necessary against sulphide related stress cracking.
