Kammprofile gasket style HEG-C1 consists of parallel root core for use in confined location including male and female, tongue and groove, and recessed flange arrangements. HEG-C2 design consists of parallel root core with integral centering ring for correct gasket position within the flange bolt circle. This design is recommended for use on standard raised face and flat face flanges. HEG-C3 design is similar to HEG-C2, however it employs loose fitting centering ring which reduces the possibility of damage to the core as a result of mechanical and thermal shock.
SWG and Kammprofile gaskets can be used on many similar duties depending on user preference. However, the relative potential incidents while using SWG can be summarized as:
Flanges are bowed.
Flanges rotation occurs.
Flange faces are out of parallel.
Thermal movement of flanges is likely.
Radial shear of gasket expected.
In conclusion, Kammprofile gaskets are ideal replacements for SWG and Metal Jacketed Gasket as following reasons;
Low seating stresses required due to highly conformable facing materials.
A selection of facing and core materials can be specified to suit the application.
Profiles available in a variety of forms and to a variety of standards to enhance the sealing performance.
Robust and has high blow out resistance.
Able to refurbish. Helps reduce raw material cost.
