工程常见问题
SCH 40 and SCH 80 cover most transmission and gathering lines. This table lists both for NPS 2"–24" layout and freight estimates.
Most international EPC contracts specify PSL2 for stricter testing and traceability. We quote and test to the PSL level on your RFQ.
CVN samples are tested in our in-house lab or at the mill line per API 5L PSL2 — not through third-party agency branding on our website.
Yes — line pipe, coating and field joint materials can be quoted together from Hengzhenyuan production and coating lines.
