Houghton Stack Guard
Stack Guard is a ready-to-use, preservation fluid recommended for the internal protection of wellhead control stacks, motion compensation and other hydraulic equipment that, after periods of storage, will be commissioned to operate with water-based hydraulic fluids.
Stack Guard incorporates corrosion inhibitors to provide both the liquid phase and vapor phase corrosion inhibition, effectively preventing corrosion-taking place in and above the liquid level. This is important when pockets of air could be left in a system or hardware.
Stack Guard also incorporates lubricity additives and can be used for FAT testing specifically of BOP control equipment.
