Type
RCMG The CMG IRTJ
Type
RCMG ring gaskets
are manufactured according to ASME B16.20 : 1999 and API 6A. The type R oval configuration was the
original design and was followed by the type R octagonal which offered more specific contact areas.
|
|
|
Type RCXMG
The CMG IRTJ Type
RCXMG
pressure-energized ring gaskets are manufactured
according to ASME B16.20 : 1999 and API 6A. The type RX series is of higher strength
materials designed primarily for well-head pressures of 700 bar and beyond. |
|
|
Type BCXMG The
CMG IRTJ
Type
BCXMG pressure-energized ring gaskets
are manufactured according to ASME B16.20 : 1999 and API 6A. The type BX series is of higher strength
materials designed primarily for special applications involving high pressures up to 20,000 psi. |
The CMG IRTJ type RCMG metal ring joint
gaskets
are manufactured according to ASME B16.20
:
1999 and API 6A. The type RCMG oval configuration
was the original design and was followed by
the
type RCMG octagonal which offered more specific
contact areas.
