Metal Jacketed /Heat Exchanger Gasket consist of softmaterial filler and a metal cover. The filler material forces metal to deform so that it gives effective sealing. The jacket and filler materials are selected keeping in mind the chemical performance and to optimize the temparature. These gaskets are used in heat exchangers, pressure vessels, tanks etc.
Following are the reasons as to why welded construction in metal jacketed gasket should be preffered instead of one piece metal jacketed gasket:

•    1.Cost effective due to reduced metal consumption.
•    2.With welded pass bar construction, primary sealing is added to the gasket, thus in case of any leak occures through the      pass bars,primary seal maintains its function.
•    3.Less time to manufacture
•    4.Longer sealing life.
