Flange Gasket

Spiral Wound Gasket With Inner And Outer Ring

Spiral Wound Gasket with Inner And Outer Ring adopts high-quality SUS304 or SUS316 ("V" or "W"shape) metal strips, other alloy materials and some flexible materials like graphite, asbestos, PTE and non-asbestos, which are overlapped and wound spirally with each other. The metal strips are fixed on the initial and terminal ends by means of spot welding. Spiral Wound Gasket has the best resilien ce among the semi-metal hermetic gaskets. Its structural density can be made subject to different locking forces. Also the internal and external steel rings can be used to control its maximum compaction. It's not demanding for the surface precision of the flange sealing surface contacting the spirally-wound gasket. It's especially applicable for such occasions as uneven load, slack joint, periodical changes of temperature and pressure, impact or vibration. It's an ideal static seal element for flange connection in valves, pumps, heat exchangers, towers, manholes,handholes and so on.

Spiral Wound Gasket with Inner And Outer Ring

Feature:

  • Little deterioration of the filler material at high temperature,oustanding long-term seal ability even under high temperatures and high pressures.
  • Sealing,especially gas sealing, is superior to that of asbestos gasket.
  • sealing remains outstanding even under servere conditions such as pressure fluctuations and heat cycles.
  • outstanding sealing even at cryogenic temperature.
  • Excellent seal ability is maintained making it possible to apply this for corrosive fluids by selecting the Appropriate materials.
