Ring type joint gaskets are designed to seal by "initial line
contact" or by way of a wedging action between the mating flange and the
gasket. By applying pressure to the seal interface through bolt
force, the softer metal of the gasket flows into the microfine structure
of the harder flange material, creating a very tight and efficient
seal.
CROSS-SECTION
Oval Type
The contact face has an oval shape. It provides a high reliability
seal. These gaskets comply with ASME B-16.20.
Octagonal Type
More accurate in terms of dimensions and surface finish than the oval type because
it consists of straight surfaces only. A higher torque load is required
to flow the gasket material into the flange facings imperfections. These
gaskets comply with ASME B-16.20.
BX type
Designed to API 6A. Can be interchanged with the oval and octagonal
series with identical reference numbers, and used in the same flange
grooves.
RX type
Designed to API 6A for use with grooved flanges for special applications
involving high pressures from 5,000 to 15,000 psi.
