Double Metal Jacketed Gasket

What is a double jacketed gasket?

A double jacketed gasket consists of a curved metallic tube with a wide C-shaped profile, and a second metal piece that bridges the inside of the C-shape’s opening, with filler material filling the interior space.Double jacket gasket with soft pliable core, surrounded by a metal jacket that totally or partially encloses the filler material. Partition bars can be incorporated , integrally or welded into the gasket.

The jacketed gaskets are formed for a soul of soft material (FM, PTFE, graphite, etc.) and at the same time this material is partial or totally covered for a ductile metal sheet. The quality of the material for jacketed gaskets has to be selected in function to the work pressure and with the fluid which will be on contact. Thanks to its comprehensible and light structure are most indicated than the totally metal gaskets in pressures and temperatures.
The jacketed gaskets can be produced with one or various nerved disposed in different configurations. Can be produced basis on the regulations as the ASME 16.20 or according customer specific specifications. The most common materials used for the fabrications of the jacketed gaskets are metal materials as copper, aluminum, AISI 304,316L, 321, and as a filling material: mineral fiber, graphite, PTFE, etc.

What is the use of metal jacketed gasket?

The metal jacketed gaskets especially are used in the area of the chemical, petrochemical and refinery industry as well as in the apparatus construction. Metal jacketed gaskets are particularly ideal for sealing flat heat exchanger surfaces, gas pipes, cast iron flanges, and autoclaves and similar.
