Corrosion under insulation (CUI) is one of the most pervasive and
difficult issues to prevent. Whether it’s insulation or fireproofing
covering piping, pipelines, tanks or pressure vessels, the damage caused
as a result of CUI can pose a major threat to your operation. Factors
like the environment, third party damage, or service can directly impact
the rate and extent of corrosion. While coatings on metal may be
effective for a period, once the coating begins to deteriorate, any
moisture held in or under the insulation will inevitably find the failed
coating and begin to cause damage.
Russell NDE is familiar with environments that experience
consistent, if not extreme, changes either from seasonal differences, or
regular shifts in temperature due to industrial process needs. Swelling
and contraction of insulation can vary, reducing the effectiveness of
the protection provided by coverings.
When all of these factors are taken into consideration, it becomes clear that, without an effective predictive measure available, the best course of action to protect your equipment is a
routine inspection of vulnerable installations. CUI and CUF inspections
can detect if corrosion is widespread. Once corrosion has been detected, you can repair your pipes, tanks and vessels before
significant corrosion requires a larger capital outlay to repair or
replace, incurring possible delays in production and loss of revenue.
Russell NDE’s bracelet probe is an effective, non-destructive inspection tool. Corrosion is rapidly detected in real time at speeds up to 1 meter/minute through insulation (up to 6.35cm/2.5” thick), fireproofing, and aluminium and stainless-steel jackets.
