Pipeline pig indicates inspection readiness

摘要

PECAT, a pigging-based inspection tool supplied by Circor Energy-Pipeline Engineering, is helping operators and contractors schedule and plan effective inline inspections (ILI) of pipelines. Pipeline inspections identify and locate defects and in-service damage that could potentially result in pipeline failure, if not repaired. The inspection operation is performed by "smart" pigs, which vary in technology and complexity, depending on the assessment they will be used to perform. It is accepted practice for most oil and gas pipelines to undergo ILIs as part of their ongoing integrity management; this may also be a legal requirement. Effective ILI operations rely on pipelines being clean, and operators want to avoid ILI tools being sent through insufficiently cleaned pipelines.
