Pipeline steel API 5L X52 PSL1 tensile strength

Posted:2020-12-02 10:56:07

Pipeline steel API 5L X52 PSL1 indicates 52000 PSI minimum yield strength and 66000 PSI minimum ultimate tensile strength, which is equal to min. 360 Mpa API 5L X52 PSL1 yield strength and Min 460 Mpa API 5L X52 PSL1 tensile strength.

Pipeline steel API 5L X52 PSL1 tensile strength:

Grade	Yield Strength	Tensile Strength
	Mpa (Psi)	Min Mpa (Psi)
API 5L X52 PSL1	Min 360 (52200)	Min 460 (66700)

Pipeline steel API 5L X52 PSL1 does not require the nondestructive inspection, while API 5L X52 PSL2 shall do nondestructive examination. API 5L X52 PSL2 steel has more strict requirements for chemical composition, tensile properties, impact energy, and nondestructive testing than pipeline steel API 5L X52 PSL1.
