Independent test conducted by widely-renowned corrosion specialist, InnCoa
Proven performance of ArmaFlex® in resistance against water vapour ingress and spread of corrosion under insulation
ArmaFlex® the only material in the test not to exhibit any sign of corrosion
New corrosion under insulation white paper now available from Armacell
Luxembourg, 17 April 2018– Armacell, a global leader in flexible foam for the equipment insulation market and a leading provider of engineered foams, today announced that ArmaFlex has successfully passed an independent corrosion under insulation test conducted by InnCoa, a widely-renowned corrosion institute. ArmaFlex was proven to have best-in-class performance and was the only material in the test not to exhibit any sign of corrosion.
Corrosion under insulation (CUI) refers to the external corrosion of metal piping and vessels, that occurs underneath externally clad or jacketed thermal or acoustic insulation, primarily due to the penetration of water. The choice of insulation system is a critical factor in the mitigation of corrosion under insulation and can actively contribute to reduced operational costs.
To assess the capabilities of commonly used insulation systems with respect to the ingress of water vapour and the onset and spread of corrosion in a high humidity environment, an accelerated, 65-day test was conducted in Germany in March 2016 by InnCoa. The insulation systems tested included flexible elastomeric foams, glass fibre, polyurethane and stone wool insulation systems. The institute conducted daily visual inspections and took photographs of the insulation systems at regular intervals. Corrosion was measured by way of visual inspection of the pipe surface following the removal of the insulation systems at the end of the test period and assessed with respect to the extent to which corrosion had occurred on the pipe surface.
As Nick Wiley, Managing Director, Armacell Engineered Systems, points out, “Corrosion under insulation is a major safety and performance issue for oil, gas and chemical process industries. It is estimated that up to 10 percent of annual maintenance costs in these industries are caused by this issue, with severe cases causing reputational risk. We are delighted with the superior performance of our materials in this assessment, which confirms the excellent results that have been achieved with our closed cell flexible elastomeric insulation solutions all over the world for decades.”
A white paper published by Armacell gives a detailed insight into the applied simulation methodology and the assessment of the insulation systems tested.

InnCoa is an independent and widely renowned corrosion institute located in Neustadt/Donau, Germany. InnCoa’s methodology of working adheres to the following guidelines: Recognise – Understand – Prevent. Firstly, recognising corrosion means identifying corrosion failure. Subsequently, understanding corrosion refers to the failure analysis regarding the influences of substrate, environment and construction. This includes electrochemical and climatic corrosion tests to reproduce the generation of a failure under laboratory conditions. In this context InnCoa focuses on tailored and customer-specific corrosion tests as a valid base for the final stage – preventing corrosion. This involves an independent and objective assessment, consultation in the field of design, material selection, joining techniques and coating systems, as well as advanced training.
