Collapse from the API TR 5C3 yield, plastic, transition and elastic formulas; burst from the internal yield formula with 87.5 % wall; body yield from the plain-end area. Ratings only; the module adds the triaxial check against combined loads.

What the module covers

Pipe ratings for the pipe you actually run.

Catalogue tables stop at catalogue sizes. The 5C3 module works the ratings out from the formulas, so special grades, odd walls and your own sizes get the same treatment. It is also the strength engine the drill string and annulus modules use.

  • Burst, collapse and tensionCollapse in all four regimes: yield, plastic, transition and elastic.
  • Triaxial checkAgainst combined loads.
  • Your own grades and sizesNot only catalogue sizes.
  • Feeds other modulesSupplies the pipe ratings the drill string and casing-pressure modules use.
