API 5L X52 Pipe Specification (PSL1 & PSL2) - Octal Steel

The answer is:In case manufacturing type in X52 seamless steel pipe or welded (ERW and LSAW), the tensile strength and yield strength is the same. Higher grades means higher pressure ratings. Therefore, the bigger hydraulic test pressure would be applied for the same outer diameter and wall thickness.

Table of the Common Specification of JCOE Large Diameter Longitudinal Submerged-arc Welded Pipe Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · The difference between LSAW and ERW pipes is that LSAW pipes are produced using steel plates, ERW pipes are manufactured starting from steel coils. LSAW welded pipes In the oil and gas industry, large-diameter API 5L LSAW pipes are used to transport hydrocarbons over long distances efficiently. What Are the JCOE LSAW Steel Pipe Forming Processes?JCOE lsaw steel pipe manufacturing process is a new type of welded steel pipe forming technology that was developed in the 1990s. The main forming process of this technology is to mill the edge (or planing edge) of the steel plate before the steel plate width direction. and the steel pipe type (diameter and wall thickness).
