Preventing Corrosion Under Insulation

Heat-Flex Hi-Temp 1200 delivers enhanced durability in transit from shop to job site, and faster shop throughput.

CUI is one of the costliest problems facing the hydrocarbon processing environment today. Infiltration by outside moisture or from the process environment through seams, gaps or other discontinuities in steel under insulation can lead to major equipment outages. Whether from periodic inspection and maintenance or due to a catastrophic failure, these outages account for more operational disruption than any other cause.

Industry standards governing the current technology and best industry practices for mitigating CUI were revised and became effective in 2011. To be sure you’re in line with those standards, you have no further to look than the next generation of CUI coatings, Heat-Flex® Hi-Temp 1200, combined with new Heat-Flex topcoats for a complete product portfolio addressing a wide range of heat requirements.

In addition to improved corrosion resistance, Heat-Flex Hi-Temp 1200 delivers enhanced durability in transit from shop to job site, and faster shop throughput. Those attributes translate into reduced total cost of ownership and extended service life for high heat applications and equipment under insulation.

And all of this has been validated in aggressive mutli-cycle laboratory testing against alternatives. Rigorous protocols based on ASTM standards, conducted at the Sherwin-Williams labs where the first CUI coating was pioneered in 1999, documented better corrosion and abrasion resistance, increased flexibility and harder film.
