Spiral Wound Gasket/asbestos/graphite/PTFE/metal spiral wound
Spiral wound gasket (SWG) consists of thin metal hoop and nonmetal
filler material which are simultaneously wound.
The metal hoop is pre-formed in V or W shaped profile, which allows
the gasket to act as a spring between the flanges. It is extremely
popular due to the wide variety of available styles and sizes.
Depend on its excellent compression resilience; it is suitable for
sealing spots where the alteration of temperature and pressure are
frequent. It can be used as the static sealing element of pipe,
valve, pump, thermal exchange, condensing tower, plain hole and man
hole of flange, etc.
During the rolling-up of a profile metal tape, a filler is being
included. It is PTFE or expanded graphit. The v-profile metal tape
is produced by different metal materials or steels. The flexibility of the
gasket in pressing on direction is being upgraded due to the
