-:: METAL JACKETED GASKETS ::-



Metal Jacketed Gaskets are made of soft compressible non- metallic filler partially or fully enclosed in a Metal Jacket. The inside diameter of Metal Jacketed Gaskets works as primary seal against leakage as the gasket is thicker at edges when compressed and the outer diameter serves the purpose on secondary seal.

 

 

HEM's Metal Jacketed Gaskets are ideally suited for smooth surface applications including heat exchangers Valve Bonnets, Gas Mains, Vacuum Lines, Autoclaves, Boilers and Glass lined Equipments. Use on circular or non-circular application, requiring 20 to 30% compressibility to compensate for flange misalignment, wrapage etc. Metal Jacketed Gaskets are designed for assemblies in which the elasticity of bolts or other factors can compensate for joint relaxation. For joint requiring close maintenance for the compression thickness or which mechanically limit the compression (e.g. Metal to Metal) The Metal Jacket Gaskets are Normally Not Recommended.



We manufacturer complete range of Metal Jacketed Gaskets as per ANSI, DIN,BS-5500 for Standard Flanges.

We also design and manufacturer Gaskets for special non- standard flanges and with Pass Partion Rib's for Heat Exchangers.

 

SINGAL JACKETED TYPE

Single Jacketed Gaskets are designed for moderate pressure and temperature application. The Single Jacketed Gaskets are constructed of soft heat resistant filler material partially enclosed in metal jacket.


DOUBLE JACKETED GASKETS
Double Jacketed Gaskets are most widely used Metal Jacketed Gaskets. The double jacketed gaskets are constructed of soft heat resistant filler material completely covered by two piece metal jacket that covers Inside Dia, Outside Dia and Both contact surfaces, Ideal for high temperature application, for boilers, heat exchangers etc.

Style - DJ2 is similar to style - DJ1 except here with double jacket, the soft filler material is enclosed in double shell too. This style is most suitable for vary high pressure and temperature application.


DOUBLE JACKETED CORRUGATED GASKETS

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.
