1 Scope
This Technical Report illustrates the equations and templates necessary to calculate the various pipe properties given in International Standards, including
— pipe performance properties, such as axial strength, internal pressure resistance and collapse resistance,
— minimum physical properties,
— product assembly force (torque),
— product test pressures,
— critical product dimensions related to testing criteria,
— critical dimensions of testing equipment, and
— critical dimensions of test samples.
For equations related to performance properties, extensive background information is also provided regarding their development and use.
Equations presented here are intended for use with pipe manufactured in accordance with ISO 11960 or API 5CT, ISO 11961 or API 5D, and ISO 3183 or API 5L, as applicable. These equations and templates may be extended to other pipe with due caution. Pipe cold-worked during production is included in the scope of this Technical Report (e.g. cold rotary st...
