What are the effects of ambient temperature on a gasket?
These effects include bolt elongation, creep relaxation of the gasket material or thermal degradation. This can result in a reduction of the flange load.
How is gasket compression reduced?
In service, as soon as pressure is applied to the vessel, the initial gasket compression is reduced by the internal pressure acting against the gasket (blowout pressure) and the flanges (hydro static end force). To account for this, an additional preload must be placed on the gasket material. An “m” or maintenance factor has been established by ASME to account for this preload. The “m” factor defines how many times the residual load (original load minus the internal pressure) must exceed the internal pressure. In this calculation, the normal pressure and the test pressure should be taken into account.
Why do toxic fluids require a leak proof seal?
d) Integrity: Toxic fluids require totally leak proof seals to prevent soil contamination or threats to human life. As a consequence, tighter and stronger gaskets may be the natural choice for these types of applications (example spiral wound gasket with outer ring vs. non-asbestos gasket)
