Advances in stone wool mandrel wound pipe insulation allow owners and maintenance managers to combat the risk of Corrosion Under Insulation (CUI) better.
In the industrial, marine and o shore industries, operational excellence is critical. CUI can considerably reduce the potential service life of industrial plants, with ongoing maintenance leading to shutdowns and overhauls that impact operational e ciency and increase operating costs.
Recently, the insulation industry has taken a substantial step for- ward with a tailored solution that addresses operational pain points. e latest o ering from manufac- turer ROCKWOOL includes an exclusive binder water repellency technology known as WR-TechTM, incorporated into the company’s ProRox® PS 960 and 980 mandrel wound pipe sections. It has proven to mitigate CUI risk and deliver signi cant bene ts over competitive insulation solutions.
Testing was impressive, with both products demonstrating lifetime durable five times (5X) lower water absorption in the relevant CUI temperature range, compared to open- cell structured insulation that meets the best currently available standards. It also offers 5X higher water repellency*, resulting in the potential for
a lower total cost of operation and increased on-site safety. e potential for reduced repair, replacement and maintenance costs makes ProRox® PS 960 and 980 with WR-TechTM attractive options.
e global corrosion authority, NACE International, states that “Because CUI is a product of wet metal exposure duration, the insula- tion system that holds the least amount of water, the lowest amount of leachable chlorides, and dries most quickly should result in the least amount of corrosion damage to equipment.”**
Advantages:
• Lowest water absorption and highest water repellency per the most commonly used standard*
• Open vapor structure enables fastest available water dissipation
• CI low-leachable substances that exceeds ASTM C795
• Backed by best-in-class service and expert technical support
