Disc Springs (Washers) - Gasket Assembly Applications

Rondelles à ressort (Belleville) – applications d'assemblage de joint d'étanchéité

Use the elastic properties of disc springs in the flange system to maintain a positive seal under varying thermal and mechanical operating conditions.

Disc Springs help to eliminate gasket leakage by maintaining sufficient load under the follow

ing conditions: ● GASKET SET ● BOLT CREEP ● LOSS OF GASKET RESILIENCY ● VIBRATION ● SHOCK LOADING

FLANGE MEMBERS

● Preload by torquing bolts to proper operating condition for gasket loading. ● As unit heats up, temperature differences occur be tween flange members and bolts, causing flange mem bers to grow in relation to bolt. ● This growth further compresses disc springs, thereby not damaging bolts or compression gasket. ● As bolt temperature approaches that of flange members during stable operations, disc spring relaxes to original preload position, thereby producing the optimal gasket sealing force.
