There are many varieties of gaskets, according to the structure
of the theme information is divided into non-metallic, semi-metal and
metal gasket three categories.
Nonmetallic gasket Non-metallic gasket soft, corrosion-resistant, cheap, but the temperature of the copper sets of manufacturers to withstand poor pressure function. Used for temperature in the temperature of the medium, low pressure vessel or pipe flange seal. Non-metallic gaskets include rubber mats, asbestos mats, asbestos rubber copper pad pads, flexible graphite mats and polytetrafluoroethylene pads.
2. Semi-metal gasket, also known as metal composite gasket. Non-metallic materials, although with good flexibility, compression and bolt valve copper sleeve load to a low level of strength. But it is mainly determined that the intensity is not high, poor resilience, not suitable for high pressure and high temperature occasions. So the combination of metal materials, high strength, good resilience. Full of high temperature characteristics. Constitute a spacer which is constructed in combination. That is, semi-metal gasket. Semi-metal gaskets are mainly metal coated gaskets, metal around the gasket, metal corrugated fit pads, metal teeth fit pads and so on.Metal gasket. In the high temperature and high pressure and load cycle frequency and other harsh operating conditions, a variety of metal materials is still the preferred choice of gasket material, commonly used information are copper, aluminum, low carbon steel, stainless steel, chromium nickel alloy steel, titanium Monel Wait. In order to reduce the bolt load and ensure a compact structure, in addition to the metal flat pad as far as possible using narrow width, a variety of cable touch characteristics of the ring pad structure is its preferred way.
