This study evaluates corrosion-inhibited mineral wool insulation under real-world conditions using ASTM C1617 and G189 testing standards. The research focuses on how these inhibitors impact corrosion rates, comparing performance against non-inhibited alternatives. By simulating field conditions, we assess long-term effectiveness and practical benefits in mitigating CUI.

Through controlled exposure testing, we analyse corrosion rates, environmental factors, and material interactions. The findings provide valuable insights for engineers, specifiers, and asset owners seeking durable insulation solutions that enhance asset integrity and reduce lifecycle costs.

This white paper highlights the importance of a multi-pronged approach to CUI prevention, combining water repellency with corrosion inhibitors for enhanced long-term protection. As LNG plants face increasing demands for reliability and safety, selecting the right insulation materials is critical for reducing maintenance costs, unplanned downtime, and the risks associated with CUI.
