Corrosion under pipe supports (CUPS) is a persistent integrity threat in above-ground piping systems because support interfaces create the exact conditions that accelerate localized attack: coating wear at contact points, trapped moisture films in tight crevices, and electrical continuity that can promote galvanic effects—especially in salt-laden coastal and offshore environments. This article in Corrosion Management (Institute of Corrosion) introduces the RedLineIPS SmartPad System as a fiber-reinforced plastic (FRP) interface solution specifically engineered to reduce these corrosion drivers at pipe support locations. 

The article explains how the SmartPad System uses a saddle-shaped design and “tried-and-true” components to distribute stress, avoid point loading, and help preserve protective coatings at the support footprint. A central feature is the integrated closed-cell Hydroseal gasket, which creates a water tight seal when installed, limiting moisture accumulation and reducing the formation of thin electrolyte films that enable crevice-style corrosion processes. Because the system is fully non-metallic at the interface, it eliminates metal-to-metal contact and is positioned as a practical way to reduce galvanic corrosion risk at support points. 

A major operational advantage emphasized in the article is maintainability: installation, removal, and reinstallation are described as achievable in minutes (or seconds) without epoxy, welding, or line shutdowns. This enables rapid visual inspections and reduces dependence on expensive inspection methods such as ultrasound and radiography, improving total cost of ownership. The article also notes broad applicability across oil & gas, petrochemicals, power generation, and water/wastewater, and references early coastal/offshore adoption by major operators.

Key mechanisms covered

• Crevice / moisture-retention corrosion at pipe–support interfaces where electrolyte films persist 
• Galvanic corrosion risk reduction by eliminating metal-to-metal contact with a non-metallic FRP interface 
• Coating wear and point-loading damage addressed through a saddle-shaped load-distribution design 
• Moisture ingress control via a closed-cell gasket that forms a water tight seal
• Inspection-driven corrosion risk (solutions that hinder access increase likelihood of late detection) mitigated by rapid remove/reinstall for visual checks
