Metal toothed gasket is a kind of solid metal gasket. Generally, a high-precision CNC lathe or special CNC lathe is used to process the two sides of the metal flat gasket into a 90-degree intersection angle to produce a wave-shaped data tube. The groove, because the contact with other sealing surfaces is a line contact of several inscribed circles, has a labyrinth sealing function. Different metal materials can be selected according to different materials and working conditions. In most cases, tooth-shaped gaskets can be combined with other non-metallic materials to achieve a better sealing effect. Gaskets can be formed by referring to metal tooth shapes. If the sealing layer is not used directly, a good sealing effect can be achieved, but it is very easy in high-pressure places.
Causes damage to the surface of the flange. Therefore, it is generally required that the roughness level of the sealing surface is above Ra1.6um. Special working conditions such as extremely high temperature, strong immersion, etc. require special materials. Metal tooth gaskets can also be produced/manufactured with the following special materials: stainless steel 304L, 321, 316T1, 309, 347, 410, duplex steel 2205 31803), Mongolia MONEL (400), INCONEL (600.625) INCO10Y 800 825) all HASTEI0 (B2276 up to 2 special no bid or full product
Metal toothed gasket features:
1. The lower preload force has an excellent sealing effect even in environments with high pressure, especially in places where high temperatures, high pressures, and changing working conditions are the traditional gold-heavy coils. Ideal replacement for thermal pads and metal-clad potential pads.
2 Pure metal toothed gaskets are easy to damage the flange surface, so the flange sealing surface must be processed when replacing the gasket.
