Metallic Gaskets are used for sealing higher temperature and pressure applications, where non-asbestos materials will fail. Typical applications are for heat exchangers, compressors, condensers, pumps, and valves.
Metallic gasket products are available in a variety of styles:
Made by winding alternating strips of metal and soft filler material, such as flexible graphite or PTFE. Ideal for standard flanges, heat exchangers, boiler handholes, manholes and other high temperature, high pressure applications. This style has many variations and can be made from many different metals and may have an inner ring, outer ring, or both depending on application.
Metal Jacketed Gaskets, as the name suggests, consist of a metallic outer shell with either metallic or non-metallic compressed fiber filler. The filler material gives the gasket resilience, while the metal jacket protects the filler and resists pressures, temperatures, and corrosion.
RING TYPE JOINT (RTJ)
Ring Joint Gaskets are precision machined, metal gaskets suitable for high pressure and high temperature applications. They are manufactured in strict accordance with API 6A, API 17D, and ASME B16.20. These high pressure gaskets come in a variety of types, sizes, and material combinations.
This style is composed of a grooved metal core with a layer of graphite or other composition sheet material on both sides. They are ideal for standard pipeline and heat exchanger applications. There are 3 standard styles of this gasket. Ring, Fixed Guide Ring and Floating Guide ring.
CORRUGATED METAL GASKET (CMG)
Corrugated Metal Gaskets, or CMG for short, can be furnished in several metals with various pitch grooves. These are designed for low to medium pressure applications on machined flanges.
