DS/CEN ISO/TR 10400:2011

ISO/TR 10400:2007 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 in ISO/TR 10400:2007 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 straightened pipe). Pipe modified by cold working after production, such as expandable tubulars and coiled tubing, is beyond the scope of this Technical Report.
Application of performance property equations in ISO/TR 10400:2007 to line pipe and other pipe is restricted to their use as casing/tubing in a well or laboratory test, and requires due caution to match the heat-treat process, straightening process, yield strength, etc., with the closest appropriate casing/tubing product. Similar caution should be exercised when using the performance equations for drill pipe.
ISO/TR 10400:2007 and the equations contained herein relate the input pipe manufacturing parameters in ISO 11960 or API 5CT, ISO 11961 or API 5, and ISO 3183 or API 5L to expected pipe performance. The design equations in ISO/TR 10400:2007 are not to be understood as a manufacturing warrantee. Manufacturers are typically licensed to produce tubular products in accordance with manufacturing specifications which control the dimensions
