CUI is a phenomenon that has plagued the Oil, Gas and Chemical Industry for years.

 

Billions is spent worldwide due to CUI due to unscheduled downtime, scheduled downtime for inspections and repairs, routine in-service inspection programs, preventive measures taken to mitigate and prevent CUI and the cost of new materials.

 

Root Causes of CUI
Presence of aerated water in the Insulation System 
Overall condition of Insulation system
Punctures, slipped jackets, seal deterioration, water retention
Temperature of steel and surrounding atmosphere
Corrosive contaminates species found in rainwater, acid rainwater in industrial regions, salt water, fire 
system deluge water and contaminants from the surface of steel.

 

Overall goals in the Fight against CUI

Significantly reduce energy consumption, discharge capacity and space.

Safety and protection of employees and public.
Reduce/Eliminate costly repairs and unexpected failures to increase reliability.

 

By creating a water resistant/vapour, breathable barrier which allows moisture to evaporate away, AeroBlok aerogel insulation prevents corrosion under insulation.

 

Applications include thermal piping and tanks in above and below grade applications from -273 up to 1,250°F. With low thermal conductivity and low water absorption our products are suited to situations where combination of moisture, physical abuse, or temperature will break down ordinary insulations.
