Spiral Wound Gaskets

Description

The design principle of the Spiral-Wound Gaskets

• The basic element of every gasket is the wound core.
• The V-shaped metal strip is spirally wound with the soft material filler.
• To improve the mechanical strength and other sealing characteristics, some layers at the beginning and at the end are wound without soft material and spot-welded over the total circumference.
• The constant tensile force during the complete winding process permits a defined, constant thickness of the structure.
• This gives the gasket recovery forces which provide for a reliable surface load even at fluctuating operating conditions.In the present 8 versions, the basic element is added by inner and/or outer rings as needed.Wide choice of materials for metal strip and filler.
• Suitable for high pressures and temperatures. Recommended for flanges with tongue and groove.
• Solid metal outer ring used as a centering device and compression stop.
  Used on raised face and flat face flanges.
• Solid metal inner ring. Use with high pressures and temperatures.
  Male to female flanges.
