Crack Diagnosis in Natural Gas Liquids Pipelines

Natural Gas Liquids (NGL) are a group of hydrocarbons that are a by-product of natural gas processing and refining including ethane, propane, normal butane, isobutane, and pentanes plus also known as natural gasoline. As the infrastructure to aid in the exportation of NGLs has grown so have the requirements to safeguard the assets that are used to transport these liquids by utilizing inline inspection technologies.

This white paper will focus on the deployment of an ultrasonic inline inspection (ILI) technology in an NGL line as well as a comparison of crack data analysis from the tool and Non-destructive Examination (NDE) data from field verifications.
