Spiral Wound Gasket is produced by metal strip and non-metallic strip with alternating overlapping.According to requirements of work circumstances,this kind of gasket can be produced with reinforced rings.Because of it has special advantages of high-temperature and corrosion resistance,it also can play best sealing role although with roughness sealing surface of flange.
Application:
It widely used in the areas of Power Plant,Aviation,Petrochemical,Valves and so on.
Application Medium:
Steam,Hydrogen,Nature Gas,Pyrolysis Gas,Oil Products,Acid,Alkali,Saline Solution and so on.
Applicable Standard:
ASME B16.20/ANSI B16.50,GB4622-93,DIN,JIS,HG20631,HG20610and other special size.
Advantages:
1.Excellent compressibility and recovery;
2.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.Excellent mechanical property of tensile strength and strstch rate.
4.With excellent performance of corrosion resistance,it can't break with extreme medium;it won'tgenerate large expansion and shrink.
5.It won't be softening under the condition with high temperature;it won't be harden and shrink under the condition with low temperature.
6.With the advantage of enough strength,it won't be broken under the condition with heavy load;it won't be blown out under the condition with high pressure.
