 Metallic Gaskets and Sealing Products

Metal Jacketed Gasket
Metal jacketed gaskets are semi-metallic gaskets in which a non-metallic filler is jacketed with sheet metal to produce a seal of exceptional strength. The soft filler allows for better compressibility as compared to a pure metallic gaskets. This makes for better sealability on irregular flange surfaces. The application temperature is limited by the filler material and the metalīs endurance. There is a minimum lap width whch must be taken into consideration when relatively small diameters or radii are required.
Ring Type Joint
Solid metal type gaskets are designed for use in high temperature and high pressure environments. These gaskets must perform in very demanding applications often in the presence of strong corrosive agents. Made from solid metal and machine formed to the desired dimensions and shape they are commonly found in refineries, oil and gas fields and in chemical process plants. They are available in a variety of materials. It is strongly recommended that the gasket metal be softer than the flange material.
Spiral Wound Gaskets
Spiral wound gaskets are special semi-metallic gaskets of great strength and resilience. Manufactured by spirally winding V-shaped metal strips and strips of non-metallic filler with good sealing characteristics, they are suitable for use under heavy operating conditions at high temperature and pressures. Applications include the sealing of flange joints, boilers, heat exchangers, valves and pressure vessels. Inner rings and outer rings may be added to reinforced the gasket. A range of metals and filler materials are available to suit different applications.
