Factors for the sealing performance of metal wound gaskets?

Sealing is achieved by compressing the gasket material and filling uneven sealing surfaces. This kind of seal can effectively prevent the leakage of the medium. In order to maintain this working condition, the connection part must exert enough load to resist the end-face hydrostatic pressure caused ......

How important is it to use the correct gasket?

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

Characteristics of Gaskets

Gaskets are normally made from a flat material, a sheet such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene (otherwise known as PTFE or Teflon) or a plastic polymer (such as polychlorotrifluoroethylene).

Sheet gaskets

The premise is simple in that a sheet of material has the gasket shape "punched out" of it. This leads to a very crude, fast and cheap gasket. In previous times the material was compressed asbestos, but in modern times a fibrous material such as high temp graphite is used.

Solid material gaskets

The idea behind solid material is to use metals which cannot be punched out of sheets but are still cheap to produce. These gaskets generally have a much higher level of quality control than sheet gaskets and generally can withstand much higher temperatures and pressures.
