Zerust Flange Savers are specially designed modules that have been impregnated with proprietary Zerust inhibitor formulations that provide superlative 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 vapor 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.
Pipe-to-Pipe (PTP) flanges used to connect lengths of pipe and Pipe-Valve-Flange (PVP) couplings are ideal candidates for Flange Savers. Product transmission (oil, gas, fire water, etc.) pipelines in aggressive industrial environments (H2S pitting, SO2 pitting, etc.) and harsh operating conditions would benefit greatly from using Zerust Flange Savers. Offshore oil platforms, refineries, process chemical facilities, and water treatment plants have thousands of flanges and commonly face this costly problem.
