ATRASEAL METAL JACKETED GASKETS

DESCRIPTION

Metal jacketed gaskets are proven sealing elements for use in apparatus construction, which are however increasingly being replaced at temperatures up to 550 °C by metal/soft-material gaskets. Metal jacketed gaskets offer an economical seal where sealing faces are narrow and can be produced in a variety of shapes.

Metal jacketed gaskets are manufactured using graphite, compressed fiber sheet or millboard as a soft filler, protected by an outer double jacket in various metals such as soft iron, copper or stainless steel. These gaskets can be made with integral or welded pass bars. Metallic gaskets can come in different styles like; double jacket, single jacket, or solid metal.

DOUBLE JACKETED GASKET

Double-jacketed gaskets are probably the most commonly used style of gaskets in heat exchanger applications. They are available in virtually any material that is commercially available. They are also extensively used in standard flanges where the service is not critical. Since most double-jacketed gaskets are custom made, there is virtually no limit to size, shape or configuration in which these gaskets can be made. 

 

DOUBLE JACKETED CORRUGATED GASKET

The double-jacketed corrugated gasket is an improvement on a plain jacketed gasket in that the corrugations on the gasket will provide an additional labyrinth seal. It also provides the advantage of reducing the contact area of the gasket, enhancing its compressive characteristics. A double-jacketed corrugated gasket still relies on the primary seal on the inner lap.

 

SINGLE JACKETED GASKET

The majority of applications for single-jacketed gaskets are normally 1/4" or less in radial width. This type of gasket is widely used in air tool applications and engine applications where space is limited, gasket seating surfaces are narrow and relatively low compressive forces are available for seating the gasket. 

SINGLE-JACKETED OVERLAP

In the single-jacketed overlap construction the maximum flange width is approximately 1/4". This type of gasket is used when total enclosure of the soft filler material is required and when the flange width makes it impractical to use a double-jacketed gasket
