High Strength SS304/316 Metal Corrugated Gasket Durable Metal Gasket for Sealing Solutions

Product Description

Product Description

DESCRIPTION

It belongs to a kind of metal composite gasket, also called corrugated movable pressure gasket, which is first pressed into concentric corrugated shape by metal sheet, which is provided by mechanical support by corrugation, and its resilience is determined by the form adopted, the thickness of metal, the spacing of corrugated and the height of corrugated. The soft sealing layer material is added according to the need to make the metal corrugated composite gasket have better compressive resilience, because the contact with other sealing surfaces is line contact of multiple concentric circles, so it has labyrinth sealing function. According to the different medium and working conditions, flexible graphite, PTFE, asbestos-free board or some other soft metal can be selected, which can be pasted on the two sides of the gasket, and the sealing property of the soft covering layer and the strength and elasticity of the metal can be used to achieve better sealing effect. In most cases, we recommend graphite as the sealing layer.




FEATURES
*  Excellent compressive resilience, even under the lower compression force can achieve excellent sealing performance is particularly suitable for high temperature, high pressure, working conditions in alternating occasions is the traditional metal winding gasket and metal-coated gasket ideal alternative.
*  The metal corrugated composite gasket does not damage the sealing surface and is easy to remove.
*   It can be used for low temperature and high temperature (-200°C ~+700°C) as well as for low pressure and high pressure (vacuum ~25Mpa). metal corrugated composite gaskets made of corresponding metal skeleton materials can be used in most corrosive fluid situations.
*  The metal corrugated parts can be reused, which is of great significance for larger gaskets or special materials such as heat exchanger gaskets.
