Varieties of common gaskets

There are various types of gaskets, which are divided into three categories of non-metallic, semi-metallic and metallic gaskets according to the subject matter of their structure.

     1. Non-metallic gasket. Non-metal gaskets are soft in texture, corrosion-resistant, and cheap, but the manufacturers of temperature-resistant copper sleeves have poor pressure resistance. It is mostly used for flange sealing of medium and low pressure vessels or pipes at normal temperature and medium temperature. Non-metal gaskets include rubber gaskets, asbestos gaskets, asbestos rubber copper gasket gaskets, flexible graphite gaskets, and polytetrafluoroethylene gaskets.

      2. Semi-metal gaskets are also called metal composite gaskets. Although the non-metallic materials have good softness, compressibility, and the load of the copper sleeve of the bolt valve can have a lower level of strength. However, its main determination is that the strength is not high, and the resilience is poor, which is not suitable for high pressure and high temperature occasions. Therefore, the combined metal material has high strength and good resilience. Can taste the characteristics of high temperature. A shim constructed by combining the two. This is a semi-metal gasket. The semi-metal gasket mainly includes a metal-clad gasket, a metal surrounding gasket, a metal corrugated fitting gasket, a metal tooth-shaped fitting gasket, and the like.

      3. Metal gasket. Under severe operating conditions such as high temperature and pressure and frequent load cycles, various metal materials are still the preferred materials for gaskets. Commonly used materials are copper, aluminum, low carbon steel, stainless steel, chrome-nickel alloy steel, and titanium monel alloy. Wait. In order to reduce the bolt load and ensure a compact structure, in addition to the narrow width of the metal flat pads, various ring pad structures with linear touch characteristics are the preferred method.
