Spiral Wound Gasket
1. Structure
The wound style gasket consists of "V-shape"(or "W-shape") metal tape and nonmetal tape, which are overlapped each other and wound continuously. To fasten the metal tape, both its start point and end point are tack welded.
 
2. Performance and Features
(1) Wide range of applicable working condition: high temperature and high pressure resistance, applicable to super low temperature and vacuum condition. Chemical resistant gasket is available under various medium, through change of composition of gasket.
(2) Strong stress compensation, stable and reliable sealing performance even under frequent pressure fluctuation condition. Depend on its excellent compression resilient, it’s suitable for sealing spots where the alteration of temperature and pressure are frequent, such as pipes, valve, pumps etc.
(3) Perfect sealing performance.
(4) Normal requirement of flange surface finishing which contact with gasket.
(5) Easy installation and low pre-tightening stress of gasket.
(6) Working temperature:-196℃ -700℃(not higher than 600℃ in oxidizing medium)
(7) Working pressure: ≤25MPa;
(8) Gasket coefficient: m=2.5-4;
(9) Min. pre-tightening specific pressure: y=68MPa;
(10) Max. machinable size:2800mm.
