XYMF-8827 Spiral Wound Gasket |
|
good
compressibility and rebound elasticity, with multi-channel sealing
and certain self-tightening functions, not sensitive to the surface
defect of flange clamping plane, and not binding the flange sealing
surface, convenient to be dismantled as it is easy to be adjusted to
the middle, able to partially get rid of pressure, and the influences
of temperature change and mechanical vibration; capable of keeping
very good sealing performance under some tough conditions of
circulating alternation, such as high temperature, low temperature,
high vacuum, impact vibration, etc. |
widely applied in static sealing parts
of technological pipelines, and the equipments of many industries, such
as petroleum refining, petroleum chemistry, chemistry, thermal
electricity, nuclear energy, spaceflight, spinning, medicine and other
industries.
