Beat the heat
Corrosion costs the oil & gas industry billions of dollars each year in replacement parts, maintenance, corrosion management and downtime. While the vast majority of this corrosion occurs at lower temperatures, in pipes, process equipment, valves, ductwork and areas where heat and moisture can wreak havoc on the protective coating and steel itself.
And it’s not just the heat. Even in normal operation, the temperature in these areas can fluctuate, causing stresses within the coating. If your coating system isn’t up to the task this can result in micro-cracks, which soon lead to greater issues. That’s why you need specialist coating systems to keep your steelwork and pressure systems in prime condition, ensure plant safety and reduce maintenance requirements.
CUI: What lies beneath
In any high heat application, corrosion under insulation (CUI) poses the greatest threat. CUI occurs when moisture becomes trapped between insulating materials and the equipment beneath. With nowhere to go, the moisture settles on any unprotected metal and begins to corrode the surface. Out of sight, the corrosion can only be confidently detected by removing the insulation – a costly and time-consuming process.
But there is a solution. Working with customers across the oil & gas and petrochemical segments, Hempel has developed a range of advanced coatings designed specifically to combat the threat of CUI. Designed to perform for longer in all temperatures and conditions, our CUI coatings enable asset owners to extend the inspection cycle. If applied across a plant, they can significantly reduce maintenance costs and downtime.
Tailored performance. High productivity.
Ensuring the right coating systems across your facility is critical. Temperatures vary in different parts of the plant, while adjoining processes and temperature fluctuations must also be accounted for. This makes selecting coating systems for high heat applications a challenging, specialist task. As experts in high heat and CUI solutions, we can help you match the right coating system to your precise operational and project requirements.
We also understand that application needs to be fast, and we supply a full range of quick to apply, durable and cost-effective CUI and high heat coatings that both reduce application costs and deliver excellent long-term performance.
