"M" and "Y" data are to be used
for fange designs only as specifed in
the ASME Boiler and Pressure Vessel
Code Division 1, Section VIII, Appendix
2. They are not meant to be used as
gasket seating stress values in actual
service. Our bolt torque tables give
that information and should be used as
such.
"M" - Maintenance Factor
A factor that provides the additional
preload needed in the fange fasteners
to maintain the compressive load on a
gasket after internal pressure is applied
to a joint. The net operating stress on a
pressurized gasket should be at least
(m) x (design pressure, psi).
"Y" - Minimum Design
Seating Stress
The minimum compressive stress
in pounds per square inch (or bar) on
the contact area of the gasket that is
required to provide a seal at an internal
pressure of 2 psig (0.14 bar).
Note: For a 5" OD gasket at 800 psig, Tp100 = 102ml / min. leakage,
Tp1,000 = 1.02ml / min. leakage, Tp10,000 = 0.01 ml / min. leakage.
Gb = stress at which seal is initiated; "a" = the slope of the log/log tightness
curve; Gs = intersection of the unload curve with the vertical axis (Tp1).
