A fully-coated isolation gasket that is also thin
Evolution isolation gaskets feature easier installation, tight sealing, high-temperature operation, no permeation, hydrotesting isolation, fire-safety and chemical-resistance. With a thinner, 1/8-in. design, Evolution gaskets minimize the difficulties often encountered when attempting to install thicker isolating gaskets. The full-coating encapsulation allows the gasket to be hydrotested and left in the pipeline with the same isolation properties as before it was tested. Evolution’s proprietary coating is extremely abrasion- and impact-resistant while providing chemical resistance to H2S, steam, CO, CO2 and other chemicals often found in oil-and-gas pipelines. This fully encapsulated coating also prevents the need for expensive exotic cores, as it eliminates contact to exposed metal. The Evolution gasket provides the highest tightness parameters for any product available in the market today, according to the manufacturer. It also provides the highest pressure rating of any isolating gasket available. Evolution gaskets can operate under high temperatures (rated to 500°F). — Garlock Pipeline Technologies, Inc., Wheat Ridge, Colo.
