- product description
Toothed gaskets are generally machined into a serrated shape with a 90-degree angle waveform on the two sides of a metal stainless steel flat gasket using a precision lathe.
Toothed gasket: Generally, a precision lathe is used to process concentric grooves on the two sides of a metal stainless steel flat gasket. According to different media, flexible graphite, PTFE, asbestos-free board or other soft metals can be selected and pasted on the gasket Two sides of the sheet. It can also be used directly without a sealing layer and can achieve a good sealing effect, but it is easy to cause damage to the surface of the flange in high pressure situations.
The structure type of this gasket is divided into two basic types depending on the sealing surface of the flange:
1. Toothed pad with positioning ring for flat flange
2. Toothed pad without positioning ring for concave and convex flange.
Product application: The toothed combination pad is the first gasket to be used under a low pre-tightening force. The soft sealing layer on the surface avoids direct metal-to-metal contact, and it can be reliably and tightly bonded to protect the metal flange. Damaged, even under extremely high loads. The toothed combination pad is especially suitable for high temperature, high pressure, and changing working conditions. It is an ideal substitute for traditional metal-clad gaskets at the flange connections of heat exchangers, vessels, and reactors.
