Here’s a draft product/feature spec for — assuming you’re adding a PDF generation endpoint based on API 5C3 casing design standards (e.g., burst, collapse, axial, tension, triaxial).

• If you design OCTG strings for HP/HT, deepwater, or sour wells → Yes, because the old collapse formulas are non-conservative for very high D/t.
• If you’re a student or occasional user → Try to get the ISO 10400 free via university library first; the API PDF is expensive (~$250–300).
• If you only need a quick lookup → The old 5C3 (2008/2018) is still widely used and accepted for non-critical wells.

For decades, casing and tubing steels moved through a rigid ecosystem of specs, drawings, and test reports. Field engineers in remote rigs, procurement teams, mill metallurgists, and QA auditors all relied on the same language. But that language had become fragmented: inconsistent tables, ambiguous test thresholds, and PDFs that read like archaeology.

Step 4: Axial Load for Connections

The new PDF includes specific derating factors for Premium connections versus API LTC/STC connections. Always verify connection efficiency (usually 60% to 100% of pipe body).
