Gasket is a kind of ring which can produce plastic deformation and
has a certain strength. Most of the gaskets are cut down from
non-metallic plates, or made by professional factories in
accordance with the specified size, the material is asbestos rubber
sheet, asbestos board, ptfe board, polyethylene board, etc. Also
useful thin metal plate (iron sheet, stainless steel) asbestos and
other non-metallic materials wrapped up made of metal gasket; There
is also a kind of winding gasket made of thin steel belt and
asbestos belt. The most commonly used is the metal winding gasket
made of stainless steel belt and graphite. According to the
different use environment, the winding belt can also use asbestos.
Ordinary rubber gasket is suitable for the occasion of temperature
below 120℃; Asbestos rubber gasket is suitable for water vapor
temperature is less than 450℃, oil temperature is less than 350℃,
pressure is less than 5MPa occasions, for the general corrosive
medium, the most commonly used is acid resistant asbestos plate. In
high pressure equipment and pipelines, the use of copper, aluminum,
no. 10 steel, stainless steel made of lens type or other shape of
metal gaskets. The contact width of high-pressure gasket and
sealing surface is very narrow (linear contact), and the processing
finish of sealing surface and gasket is high.
Low pressure small diameter threaded flange, high pressure and low
pressure large diameter are welded flange, flange thickness and
connecting bolt diameter and number of different pressure is
different.
