ASME B16.20 SS304 Graphite Spiral Wound Gasket 4 Inch
Material: Stainless Steel 304
FILLING: Graphite
Size: 4 inch
The Stainless Steel Spiral Wound Gasket 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.
The metal spirally-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.
