Wave ring gasket with outer ring
- product description
Toothed shim is a metal flat ring, a sawtooth metal shim processed into a 90-degree angle waveform on the ring plane.
In some occasions where flexible composite materials cannot be adapted or used, only flat gaskets, toothed gaskets or corrugated gaskets of pure metal can be used. Metal flat gaskets and metal toothed gaskets are equivalent to the metal skeleton of flat composite gaskets and toothed composite gaskets (the processing technology and technical requirements are exactly the same). Because they only contain metal materials, they are classified as metal gaskets. In order to reduce the pre-tightening force and improve the sealing performance, the following measures are usually taken:
A. When soft metals are used to meet other requirements, it should be possible to use low hardness materials such as aluminum, copper or their alloys.
B. Change the heat treatment process to minimize the material hardness.
