Packings forHigh Pressure Service

metal separators (lead or bronze) can be installedbetween the CHEVRON
® packing might need to be reinforced toprevent undue distortion from this extreme pressure. The following are examples of some design consid- erations that can be used to overcome problems experienced with standard components (such as 432, 433, etc.).“D” filler rings can be installed in the groove of thehinge-type CHEVRON
® Vee Rings. “D” fillers can be used only with 3/8" crosssections and up with hinge type “XE” CHEVRON
® rings per illustration A, page E-7. When pressure ranges exceed those normallysatisfied with standard Style 432, 433 or 532 adapt- ers, the stronger rockhard adapters such as 260RH, 261RH and 7857RH should be considered.When a problem relates to excessive clearances,as discussed on page E-8, a close tolerance phenolic (Style 155) or bronze bushing installed behind the female adapter will act as additional support and reduce the extrusion gap. A phenolic or bronze female adapter will serve the same purpose.These configurations have been used successfullyto extend the life of CHEVRON
® Vee Rings to prevent distor-tion of the packing without interfering with the auto- matic hinge action of the rings. If the CHEVRON
® Vee Rings still tend to telescope into each other,
® packing sets. How-ever, specific applications should be considered on an individual basis, taking into account the type of equipment, size, temperature, media being sealed, pressure, surface speed, condition of equipment and any other contributing factors.
