Spiral Wound Gasket

Spiral Wound Gasket is widely used in the areas of Nuclear Plants, Aviation, Petrochemical, Valves and so on.
Application Medias: Steam, Hydrogen, Nature Gas, Pyrolysis Gas, Oil Products, Acid, Alkali, Saline Solution and so on.
Introduction:
1.With better compressibility and recovery;
2.With plastic property, it can adapt to the sealing surface with concave and convex to fill the gap of sealing surface and ensure to keep the better sealing performance under the environment with fluctuation temperature and pressure.
3.With better mechanical property of tensile strength and stretch rate.
4.With excellent performance of corrosion resistance, it cant break in some extreme medium; it wont generate large expansion and shrink.
5.It wont be softening under the condition with high temperature; it wont be harden shrink under the condition with low temperature.
6.With the advantage of enough strength, it wont be broken under the condition with heavy load; it wont be blown out under the condition with high pressure

Spiral Wound Gasket produced by pre-loaded profiled corrugated metal strip and non-metallic strip with alternating overlapping.
