FeTech Flange Washers help create a more reliable flange assembly by maintaining residual gasket/bolt load and evening load distribution. They are specific apply to petrochemical/oil & gas industries, which utilize piping flange joint assemblies, dictating a low tolerance for fugitive emissions. Flange live loading, which is a process imperative to control gasket leaks in piping and refining operations, depends on the mission-critical performance. The flange washers are designed to maintain sufficient bolt tension and resultant gasket stresses in high temperature and high pressure applications where safety and emission containment take priority.
