The latest standard for calculating performance properties of casing and tubing is , published in February 2026 . This new release officially transitions the document from a Technical Report (TR) to a Recommended Practice (RP), superseding the previous API TR 5C3 (2018) and its 2019 addendum. Core Content & Scope

Old practices often ignored axial tension's effect on collapse. The re-emphasizes the API biaxial method: when you apply tension to a pipe, its collapse resistance decreases . The formula ( \sigma_z = \sigma_a + \sigma_b ) (axial stress plus bending stress) now includes more precise correction factors for tapered strings.
