Spiral Wound Gaskets with Outer Ring is wound alternatively by V or W shaped metal hoop and non-metal filler of various kinds of materials selected based on specific working condition. spiral wound gasket with outer ring gasket provides additional radial strength to prevent gasket blowout and acts as a compression stop.
Application of Spiral Wound Gaskets With Outer Ring
It is suitable for sealing flange joints,manhole and handhold covers,tube covers,boilers,heat exchangers,press vessels,pumps,compressors and valves;industries such as petrochemical,pharmaceutical,shipbuilding,and food processing ,in power industries and nuclear power station.They are ideal for steam,oil,liquids,gases,acids,alkalines,various organic mediums and solvents.
Standards of Spiral Wound Gaskets With Outer Ring
ASME, JIS, DIN, EN，size as requirements
1.Metal strip: the processed metal strip has good elasticity and recovery. It provides the filler enough tensile strength.
2.Filler: this part is the main body of the gasket and different material is used in different conditions
3.Centering ring:the centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plate or painted to avoid corrosion. Other materials are available on request.
4.Inner ring:inner ring is used to avoid excessive compression due to high seating stress in high pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic strip.

Feature of Spiral Wound Gaskets With Outer Ring
1.Excellent compression resilient
2.High-temperature and corrosion resistance
3.Keep good sealing performance under high vacuum and shock vibration conditions
4.Multichannel and certain self-tightening sealing function
5.Eliminate the influence of pressure , temperature change and the mechanical vibration for its insensitivity to surface defect of flanges
