Metal Jacketed Gasket(Double Jacketed Gasket)

Item No.:ZD-G2020

Description:Metal jacketed gaskets comprise of a thin metallic outer shell enclosing a resilient filler material. The gaskets metal case protects the resilient filler and is resistant to pressure, temperature and corrosion.Metal jacketed gaskets are hand made and are available in many shapes and sizes with a selection of metals and fillers available. Internal ribs of any configuration are available.These gaskets are widely used in heat exchanger applications but require good and even flange surfaces along with high bolt loads to effect a seal.

Single jacketed gaskets have one surface and both OD and ID covered by the metal jacket. Suitable for narrow flange widths in low pressure valve / pump applications

Double jacketed gaskets are completely enclosed by a two piece metal jacket covering OD, ID and both sealing surfaces. Widely used in heat exchanger applications and suitable for corrosive and high temperature service.

Internal ribs (pass partition bars) can be integral or welded welded as in both types, the primary seal is safely maintained.

Application: those with simple shapes are applied in pipeline flange and sealing surface of internal-combustion machines, and those with complicated shapes are used in the flange cover of heat exchanger, etc. The general gaskets are 10-25 MM wide and 2MM-8MM thick, and can be used in a maximum work pressure of 6-10Mpa.

Definition: the cladding materials are different metal panels of 0.1MM－0.5MM thick, and the internal cladding materials are made of non-metal materials.

Filler Material: Normally graphite,PTFE, ceramic and non asbestos are also available.

Jacketed Material：Tin-plate、SS304、316、Copper、aluminum,ect.
