Calculate Predicted Failure Pressure and Remaining Life
APTITUDE™ is an accurate and easy-to-use crack evaluation application used by pipeline operators to calculate predicted failure pressure and remaining life of steel pipelines.
Combined with Structural Integrity’s fracture mechanics expertise, APTITUDE can provide an efficient and cost-effective way for operators to complete engineering critical assessments (ECAs) and PFP analyses.
Use of this application helps to ensure safety, asset optimization, and adherence to updated criteria defined by 49 CFR §192.712 – Pipeline Safety Regulation.
APTITUDE finds the optimal re-assessment interval based on criteria defined in updates by calculating a predicted failure pressure (PFP) through multiple industry-accepted methods.
APTITUDE calculates critical values and provides useful recommendations:
APITTUDE has been used by several major pipeline operators in the U.S. to address crack and crack-like defects discovered in their pipeline systems. Some common applications include:
Structural Integrity Associates, in 2024, convened a joint industry project (JIP) to upgrade APTITUDE to a web-based platform to further benefit operators. Enhanced capabilities and accessibility became available in March 2025, with added features introduced later that same year.
