Ginseal Spiral Wound Gaskets - Heat Exchanger Swg (JSG-SWH)

Description

Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of
Filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support. These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.

How to choose Filler
The main sealing part is filler which is made up of SS strip and non- metallic filling tape, the material can be changed according to different chemical compatibility requirements,
Graphite filling strip is supposed to used in high temperature environment,
PTFE filling strip is for acids and other corrosive mediums
Non - asbestos its use increased when the health problems with asbestos became known. Only recommend for low temperature less severe applications due to the rubber content.
Ceramic is in extremely high temperature applications. The filler is not so common as it cannot achieve the same leak tightness as graphite
