    Transfer lines are often overlooked. Operators focus inspection resources on larger pipelines, yet shorter transfer lines carry their own serious safety risk. Many are dismissed as "unpiggable" due to tight bends, Tee-pieces and schedule changes that exceed the capability of conventional inspection tools.

    In this case study, we share how Cokebusters' MK5 Smart Pig successfully inspected a transfer line previously considered impossible to assess and the significant defect it uncovered using axial measurement and C-scan data.

    What You'll Learn

    • Why transfer lines are frequently under-inspected, and the safety risk this creates
    • How the MK5 Smart Pig's titanium body and 5 MHz ultrasonic probe array navigate tight bends and Tee-pieces that exceed the limits of conventional tools
    • The specific defect identified in this project: a 50.3% wall loss finding, located precisely using axial measurement and C-scan data
    • How the finding was verified on-site, with full correlation between inspection data and physical defect condition
