Hydrostatic Testing for Pipelines with SCC Threats

Hydrostatic testing, or pressure testing, has been an accepted industry method for verifying the integrity of pipelines. Integrity assessment methods can be used for either maximum allowable operating pressure or other threats such as stress corrosion cracking (SCC). This article will focus on pipelines that have been in service for a long period concerning time-dependent issues such as SCC and static-type threats, and the use of hydrostatic pressure testing and crack growth modeling for evaluating such threats.
