Metal Jacketed Gaskets are metal jacketed gaskets with a metal shell and metal or non-metal compressed fiber packing. The packing material provides elasticity, and the metal shell protects the packing and resists pressure, temperature and corrosion.
Metal Jacketed Gaskets can be used as heat exchanger gaskets, as well as pumps, valves, etc., although their recovery and resilience are limited. Gasket sealing is effective under high bolt load, smooth flange surface finish, and flange flatness.
The gasket materials used for its structure are:
Metals include soft iron, carbon steel, stainless steel, Inconel, Monel, nickel, aluminum, brass, copper, etc. Non-metals include compressed fiber grinding plates, polytetrafluoroethylene, Tanged insert graphite, ceramics, etc.
The types of Metal Jacketed Gaskets are:
Metal Jacketed Gaskets, the filling material is wrapped in a metal jacket, covering the inner and outer diameters of the gasket
Double-sheathed washer, the filling material is enclosed by a two-piece metal sheath, covering the inner and outer diameters and two contact surfaces. The width of the gasket can be made as narrow as 8mm. The nominal thickness is 3.2mm. With integral/welded partitions with sufficient bolt connections.
French gasket, the filling material is wrapped in a metal sheath, covering the inner diameter of the gasket and the sealing surfaces on both sides.
The solid corrugated metal gasket does not contain corrugated non-metallic packing, which can provide multiple seals on the gasket surface. At least 3 corrugations, the thickness of the gasket is the same as the corrugation pitch, which can be 3.2mm, 4.8mm, 6.4mm.
