SPECIAL HEAT EXCHANGER GASKETS
Special HE-CGI Gaskets with spiral wound outer ring
(ALTERNATIVES HE-CG, HE-CGI)
Flexitallic special HE-CGI Gaskets with spiral wound outer ring are primarily designed for TEMA male and female flanges
and are custom built to suit the design conditions of individual heat exchanger vessels. These gaskets are available in
an extensive range of materials.
This style incorporates several special features, as follows:
1. The outer wound nose to ensure correct sealing element location in the flange recess.
2. A spiral wound sealing element to ensure a positive seal under fluctuating temperature and pressure conditions.
3. A solid metal inner ring to protect the sealing element and act as a compression stop. As an optional extra,
inner rings can also be supplied with nylon location screws to secure the gasket to the flange on assembly.
4. Can be supplied with pass partition bars in any configuration. Pass bars are secured to the inner ring and can
be supplied in either solid metal or double jacketed construction.
Heat exchangers with flat face or raised face flanges should utilize style CG and CGI spiral wound gaskets.
