X52 PSL2 spiral welded pipe is a core grade in API 5L "Pipeline Steel Specification". It belongs to the PSL2 category of steel for oil and gas transportation. This steel grade, through low-carbon microalloying design and controlled rolling and cooling process (TMCP), ensures high strength and high toughness while having excellent resistance to hydrogen-induced cracking (HIC) and hydrogen sulfide stress corrosion (SSC), making it the preferred material for onshore and subsea oil and gas transportation pipelines.
