Take on the battle against CUI with Insulcon Pyrogel® products

10.03.2020
Within the petrochemical and process industry, Corrosion Under Insulation (CUI) is one of the most common failure mechanisms. CUI is any type of corrosion that occurs due to moisture (e.g. intruding water or condense) present on the external surface of the insulated process pipe or equipment. CUI can compromise the strength of the pipe and the efficiency of the insulation.

The damage can be caused by one or multiple factors, such as environment, temperature, type of material, etc. and can occur in equipment operating at ambient, low, and heated services. Moreover, CUI can occur in equipment that is in service, out of service, or in cyclic service. If undetected or not addressed to, the results of CUI can cause safety incidents due to leaks, higher steam demands, process instability and in the end even lead to an unscheduled shutdown of the process or plant, resulting in extreme high maintenance cost and loss of production.

How to prevent intruding water under your insulation?
In order to address the issue of CUI the choice of the exact type of insulation is critical. As water retention, permeability and wettability of the insulation have a large influence on CUI, the insulation, which holds the less amount of water (or dries the quickest), is thus the one which will cause the least damage. The ideal insulation material should therefore have excellent insulation values, should be easy to handle, but at the same time should not absorb water. 

Pyrogel® is a flexible, high-performance, aerogel blanket insulation, designed for the use in high temperature industrial applications. Specially developed to deliver superior thermal performance while offering excellent protection against CUI. Pyrogel® is hydrophobic (durable water repellent) yet breathable and ensures long-lasting water resistance for both the insulation layer and the underlying assets. The gas permeable properties allow any trapped water to evaporate out, preventing prolonged contact. Therefore Pyrogel® will keep your assets drier for longer, thus avoiding safety incidents, preserving process conditions, and saving energy. Pyrogel® is THE solution against CUI! 

Customized Pyrogel® parts by the Insulcon Group
Although available in standard rolls, the installation of Pyrogel® is even more efficient, if you use our pre-cut, customized shapes. Due to our large in-house CNC driven machinery, we are able to manufacture tailor-made shapes such as reusable lobster tails for elbows. On request, we can also help you with the engineering of the complete pipe work insulation and even mark the several layers during production, which makes installation on site easier for the installer. During the last years, The Insulcon Group has executed several large projects within the petrochemical and process industry. A reference list is available upon request.
