Armaflex insulation materials minimize the risk of corrosion under insulation (CUI)

Corrosion Under Insulation (CUI): a Billion-dollar problem for the Industry


Corrosion under insulation causes catastrophic failure and prolonged downtime. It is estimated that 40 to 60% of pipe maintenance expenditure is down to CUI, costing the Oil and Gas Industry around $1 Trillion globally per year. The right choice of insulation can significantly reduce downtimes and maintenance costs.


Armaflex insulation materials minimize the risk of Corrosion Under Insulation (CUI): outstanding results in a new CUI test of the Endures / TNO institute

As the renowned Dutch TNO institute has confirmed in a 6-month test, Armaflex insulation materials minimize the risk of corrosion under insulation (CUI).

Even under the harshest offshore conditions as simulated in the test, closed-cell Armaflex significantly reduces the danger of corrosion thanks to its integrated water vapour barrier.

The test method developed by TNO-ENDURES is the first standardized procedure to assess insulation materials regarding their influence on the risk of corrosion.

The outcome of this test confirms the excellent results which have been achieved with Armacell’s elastomeric insulation materials all over the world for decades.
