Know the metal jacketed gasket

The metal jacketed gasket is composed of a metal shell and a metal or non-metallic non-asbestos filler. The filler material imparts elasticity to the gasket, while the metal sheath protects the filler and resists pressure, temperature, and corrosion. It has a gasket with a soft and flexible core, surrounded by a metal sheath, which completely or partially surrounds the filling material. The Pass separator can be integrated into the gasket, it can also be integrated or welded into the gasket. The jacket may be corrugated. The metal-clad gasket is manufactured by hand-made technology and has a variety of sizes and configurations to choose from.
Generally speaking, a very smooth surface finish is required for metal gaskets that do not fit well with metal contact surfaces. In view of the creep resistance and structural stability of most metal gaskets, the two mating surfaces can form a very tight and reliable seal. Alignment, parallelism, and flange finish must be within the specified range to obtain the best results. Metal gaskets can hardly tolerate flange surface treatment or bolting and assembly defects.
Flange surface finish is a key aspect of gasket performance. Metal, semi-metal and non-metal gasket materials interact differently with the flange surface. Each of these gasket types requires a specific range of surface finishes to achieve the best gasket performance, lowest leakage, and operational safety. Compared with semi-metal or non-metal gaskets, metal gaskets require a smoother flange finish.
