High Pressure Pipework Thickness Gauging

NOV Tuboscope Specialty Inspection Services are approved by the major classification agencies such as ABS, DNV & Lloyd's to conduct Thickness Gauging on low or high pressure pipe work.
We can measure the residual thickness of structures in critical areas like bends or flow constrictions, by Ultrasonic Thickness Gauging and at the same time we can check all related equipment like accumulator bottles and air receivers to enable repair or replacement planning. Incidentally, the highest deterioration usually occurs near bends or flow constrictions, so thorough and professional checks are a must.
Wall Thickness Gauging can be conducted together with other periodic surveys such as Derrick Inspections or Lifting Gear Surveys.
NOV Tuboscope Specialty Inspection Services is proud to be an ABS (Hull), ABS (ESP), DNV & Lloyd's Approved Service Provider for High Pressure Pipework Thickness Gauging.
