Spiral Wound Gaskets are winding by "V" shaped metallic strip and soft non-metallic filler. According to the requestment, the gaskets can be within inner and outer rings for improving the gaskets handling, fitting and versatility.
Depend on its excellent compresion resilience, it's suitable for sealing spots where the alteration of temperature and pressure are frequenty.
Basic type gasket: inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics.
Suitable for tongue and groove, male and famale or grooved to flat face flange essemblies.Inner Ring Type:
Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce trubulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring;Suitable for male and female pipe flanges.
Outer Ring Type:
Solid outer accurately locates the gasket on the flange face to give the additional radial strength to prevent gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts;
Suitable for use with flat face and raised face flanges. For class 900 and above an internal ring is recommended.
Inner & Outer Ring Type:
An inner ring and outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer side. It will prevent the corrosions on flange face at annular space;
Suitable for use with flat face and raised face flanges and specified for high pressure and temperature service, Class 900 and above or where corrosive or toxic media are present.
