API RP 1176, Assessment and Management of Cracking in Pipelines, is a recommended practice developed and published by the American Petroleum Institute providing pipeline operators with best practices in the integrity management of cracks and threats that give rise to cracking mechanisms. The current and 1st Edition of this RP was published in July of 2016.

API RP 1176 covers mechanisms that cause cracking, methods to estimate the failure pressure of cracks, and methods to estimate crack growth. Selection of the appropriate integrity assessment method for various types of cracking, operating conditions, and pipeline characteristics is also discussed. In addition, this RP reviews current in-line inspection (ILI) technology and in-the-ditch (ITD) nondestructive examination technology.
