API 5L X52 PSL2 seamless steel tube for Oxygen, water and oil pipelines used in oil and gas industry.
1. Product Description
API 5L X52 PSL2 is a kind of seamless steel pipe for oil pipeline, which is mainly used to transport oil and natural gas.X42 products are widely exported to the international market, product quality is very good, more than 20 countries customers recognized, The carbon content of X52 is higher than that of GrB and X42, which meets the higher requirements.
PSL2 is more strict than PSL1 in chemical composition, tensile operties, impact properties and nondestructive testing. In total, PSL2 is higher than PSL1, so when ordering according to API5L standard, it is necessary to indicate in the contract that whether the specification level is PSL1 or PSL2 (API5L pipeline pipe).
The surface can be painted and marked, the two ends can be threaded and blunted, the two ends of the steel pipe can be equipped with pipe caps and protective covers, and various export packaging methods can ensure the safe transportation of products.
