Double Jacketed Gaskets |
|
 |
ICDMJG1
The most popular style
for heat exchangers, the double-jacketed gasket offers complete
protection of the filler material. There is practically no diameter
limitation, with greater compressability and resilience than a similar
solid metal gasket. This gasket provides even support by the use of the
overlapped jacket on the inside and outside diameters. Also, the outside
lap helps to prevent excessive distortion of light weight flanges. The
most common filler used is graphite. A wide range of metal and other
filler materials are available if dictated by temperature, pressure, or
corrosive conditions. |
 |
ICDMJG2
The corrugated style has
increased resilience with the benefit of a number of seal points. If a
small leakage occurs across the inside edge, the corrugations act as
separate seals under moderate and even bolt loads. |
 |
ICDMJG3
This gasket employs a
metal filler rather than soft material. The result is greater resistance
to problems resulting from temperature changes. The range of temperature
is limited only by the metal selected. |
 |
ICDMJG4
This gasket is generally
used for applications where narrow width is required. The single jacket
gasket with a soft filler protects both edges of the filler material. It
is an economical answer to many gasket needs. Single jacketed gaskets
are available with corrugated metal fillers. |
 |
ICDMJG5
Affording the advantages of the standard
double jacketed gasket, the double shell style allows greater strength
and rigidity by the addition of a completely overlapping inner shell.
This gasket has a minimum flange width of 1 /4", and can be produced in
almost any diameter. As with other heat exchanger gaskets, there is a
greater variety of available metals and filler materials. |
 |
ICDMJG6
A gasket with completely
enclosed filler offering more filler protection than the standard single
gasket. Especially useful for applications requiring small flange widths
(to 1/8" ). Certain sizes may require tooling to produce. |
 |
ICDMJG7
The two piece French
Style gasket is more readily available and easier to produce than the
one -piece French Style which requires expensive tooling. The soft
filler is exposed on the outside diameter and the minimum flange width
is 1 /4". Size of diameter is practically unlimited |
 |
ICDMJG8
This gasket combines
advantages of metal shielding on the I.D. with a thick, compressable
layer of soft gasket material on either side of the metal. Metal
thickness is 26 gauge, tack welded together and then rolled over on the
I.D., acting as a shield. The layers of soft gasket materials are
available in various densities and thicknesses. |
