Long range ultrasonic testing in Nigeria

Chevron, one of the world’s largest energy companies, was having specific problems with risers due to corrosion and was subsequently looking for ways to inspect the risers without closing the whole field, which would have resulted in millions of dollars in lost revenue.

At this point SGS offered to conduct Long Range Ultrasonic Testing that can be applied for pipes in operation. Thanks to this relatively new technique, Chevron was able to check the condition of the risers and schedule shutdown for repairs, thus saving costs.

SGS offers advanced corrosion inspection for pipelines and process piping easy fit equipmentLong Range Ultrasonic Testing, also known as Guided Wave Technology, is a newly accepted Non-Destructive Testing (NDT) method for evaluating insulated pipes, cased sections, road crossings, compressor station piping, buried pipelines, tank dike piping and most piping systems which are difficult to access and which in the past could not be inspected economically.

The Guided Wave Technology screens 100 per cent of the volume of the piping inspected. A typical application of LRUT is the detection of corrosion and metal loss in pipes and pipelines.
