Spiral Wound Gaskets |
The
ICSMWG1
CMG Spiral Wound gasket has no metal ring. This style is suitable for
tongue and groove face connection and sometimes for male and female face
connection but not suitable for ordinary pipe flange of raised face.
This style is commonly used for valve bonnet, pressure vessels, etc.
|
The
ICSMWG2
CMG Spiral Wound gasket has metal inner ring. As inner ring works as
reinforcement to prevent internal extrusion or inward buckling of gasket
windings caused by compression, this style is suitable for male and
female face connection but not suitable for ordinary pipe flange of
raised face.
|
The
ICSMWG3
CMG Spiral Wound gasket is with outer metal ring. Outer ring works as 1
) centering a gasket properly between the flanges, 2) limiting bolt load
at proper compression, 3 ) preventing external expansion by compression.
For PTFE filler
gasket, this style is basically not recommended due to possibility of
inward buckling during compression.This style is most common for
ordinary pipe flange of raised face.
|
|
The
ICSMWG4
CMG Spiral Wound gasket has both metal outer and inner ring. As inner
ring works to prevent internal extrusion or inward buckling, this style
is especially recommended for the following cases.
- For
flanges NPS 24 and larger in class 900, NPS 12 and larger in class 1500
and NPS 4 and larger in class 2500 #.
- PTFE
filler material.
- For socket
welding, lapped, welding neck and integral flanges. This style is
suitable for pipe or pressure vessels using raised face flange
connection.
