Import Tips

Provide detailed chemical analysis and mechanical properties from MTRs to confirm 'other alloy steel' status excluding stainless

Measure and document OD precisely; tubing exactly at 406.4 mm may require engineering verification for 'exceeding' criterion

Comply with US oilfield safety regs like API RP 5C1 for threading to prevent reclassification as unfinished pipes
