Custom Gasket for the Refining Industry

With our 80+ years of experience in handling complex requests for industrial sealing products, Mercer Gasket & Shim is a leading provider of custom camprofile gaskets to the refining industry. Engineered for use in an application with extreme temperatures, high pressures, and irregular process conditions, this camprofile gasket featured a grooved metal core with an integral centering ring to help position the gasket within the mating flange bolt circle and a thin, bonded layer of graphite sealing material.

We formed the components of this gasket using a waterjet cutter, which has the capacity to make intricate cuts through thick materials while preserving metal’s inherent structural properties. The stainless steel core featured dimensions of 2½” in thickness x 32 1/8” OD x 30.0” ID, while the A36 carbon steel centering ring had dimensions of ¼” in thickness and 38 3/8” OD. We precision machined the concentric grooves on the inner ring, welded the two rings together, and then applied a thin layer of pure, natural graphite flake to protect the flange surfaces from damage and enhance the sealing properties. Our ISO 9001:2008 quality assurance protocols ensured we met critical material and dimensional specifications.

The design and construction provided a leak-free flange connection under wide swings in temperature and pressure, while the graphite coating eliminated fugitive emissions in this solid metal-to-metal sealing application. We manufactured two of these high performance gaskets in a one week timeframe.
