Zerust Flange Savers are specially designed components that have been impregnated with proprietary Zerust inhibitor formulations that provide unbeatable corrosion protection for flanges, valves, and welded joints. Zerust Flange Savers are available in various sizes to accommodate different pipe diameters, pressure ratings and international standards for pipeline valves and flanges. Zerust vapour corrosion inhibiting (VCI) products have successfully protected metal substrates across numerous industries for over 30 years. Crevice corrosion and weakened welds can lead to product leakage, while frozen fasteners will require time consuming maintenance. Corrosion can also change the tensioning of bolts/fasteners thereby causing gaskets to come lose and/or fail. Zerust Flange Savers can mitigate all these problems in a single application
