THERMICULITE 835 HEAT TREATED INCONEL X-750 SPIRAL WOUND GASKET

INCREASED SAFETY. PROVEN RESULTS.PROVEN COST SAVINGS.

Severe cyclic conditions? For the most demanding cyclic conditions thechoice is Flexitallic s Thermiculite Spiral ound Gasket with eatTreated nconel 0 winding.

ifferential thermal expansion and contraction of components in a boltedoint due to the effects of cyclic conditions requires that extra resiliency be

built into the oint or the gasket to compensate for fluctuating load conditions.

ormal gasket materials do not provide sufficient resiliency and thereforecannot compensate for the adverse effects of cyclic conditions. Special eatTreated nconel 0 gasket materials have been developed by Flexitallic toensure that oint integrity is maintained during thermal cycles.

n EM and End ser testing comparing the performance of standard 16SS windings vs. eat Treated nconel 0 windings precipitation hardened T nconel 0 winding material significantly increased the yieldstrength resulting in increased springback before leakage or usable recovery.
