Survey of a 48" line - largest diameter to date

Working as sub-contractors to Cooperheat MQS, Plant Integrity Ltd have carried out a Teletest ^® inspection of a 48" diameter brine line. This is the largest diameter pipe tested to date. The photographs show the transducer ring assembled on the pipe just before bends leading in one case into a road crossing and in the other into a bayou crossing. (In the latter case, the testing was done in close proximity to a large alligator!). Despite the presence of two bends in each case, Teletest ^® was able to cover the full extent of the crossings. In the case of that under the bayou, this meant 'shooting' more than 26m on pipe submerged in water.

A problem of particular concern to the oil industry is corrosion at supports. This line is clamped to saddles with a neoprene interlayer. Teletest ^® was able to 'shoot' past the supports, the signal being unaffected by them. This meant that corrosion in the support area, either over the saddle or under the clamp could be detected.

Cooperheat MQS' customer, Loop LLC, based in Cut Off Louisiana, were delighted with Teletest's performance. They advised Cooperheat MQS that they intend to place more Teletest ^® work with them in the near future.
