This month’s front cover features IRISNDT performing Guided Wave Testing (GWT) on an in-service below ground, bitumen wrapped pipe work in a UK transportation and storage facility using a Wavemaker G4mini system from Guided Ultrasonics Ltd. (GUL) This is an advanced application for Guided Wave Testing as the protective bitumen wrapping on the pipe work results in data sets that are challenging to interpret due to high attenuation rates encountered. IRISNDT have over 20 years of GWT experience and operators that are specifically trained and certified in advanced GWT applications. IRISNDT have also successfully used GWT for the detection of corrosion under insulation (CUI) surveys in the refining, petrochemical and power generation industries on pipe sizes ranging from 2” up to 48” in diameter. The pipes under test are typically in-service and can be up to 350°C pipe surface temperature. The GWT method is sensitive metal loss defect mechanisms including erosion, corrosion and de-laminations regardless of their circumferential or through-thickness location.
