· COMPOSITION
MONTERO BELPAFLEX Spiral Wound Gaskets are made of alternative spiral
windings of preformed metal strips in "V" shaped and expanded
mineral graphite (as filler). The main material used for these gaskets
is Stainless Steel AISI 316L that offers a high resiliency and confers
to these gaskets a high thermal and chemical resistance.
This type of construction makes the spiral
wound gaskets MONTERO BELPAFLEXâ suitable for almost every
industrial equipment but specially in steam lines for high and middle
pressures.
Advantages of the outer compression ring (SPIRAL WOUND GASKETS BELPAFLEXâ
TYPE SR): it provides, besides the best installation between fasteners,
protection against pressure and external agents. This ring prevents
creep deformation of the filler material and also over-compression
and avoids the "Blow out" effect caused by rough changes
in pressure and temperature.
