Semi-Metallic Gaskets

Semi-metallic gaskets are designed to provide a reliable seal in high-pressure and high-temperature environments by combining the resilience of soft materials with the strength of metal. They are essential for maintaining the integrity of flanges and joints in industrial applications, ensuring leak-proof performance under demanding conditions.

The Kammprofile gasket offers exceptional sealing with superior load-bearing capacity. It features a metal core with concentric serrations, optionally with a guide ring, and is faced with compressible materials like graphite or EPTFE. This design delivers optimal performance at low seating stresses by combining the compressibility of the facing material with limited penetration from the grooved metal core, ensuring enhanced sealing efficiency.

Metal-jacketed gaskets are particularly suitable for sealing flat surfaces of heat exchangers, gas pipes, cast iron flanges, and autoclaves and similar. By their sealing efficiency, provided by exerting strong pressure on circular rims of the flanges, metal-jacketed gaskets can stand up to 30 % of deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.

Ring joint gaskets are precision CNC-machined from solid metals, designed for high temperature, pressure, and corrosive environments. With a small installation area and high pretension pressure, they are ideal for sealing pressure vessels, valves, and cylinders.
