Discover the complete range of inner ring materials used in spiral wound gasket manufacturing. Compare corrosion resistance, mechanical strength, operating temperatures and engineering characteristics before selecting the right inner ring material for your sealing application.
The inner ring of a spiral wound gasket acts as an internal support that prevents the winding from buckling under compression and resists erosion or turbulence caused by process flow. Different inner ring materials are selected depending on process media, operating temperature, pressure and compatibility with the winding and filler.
Select an inner ring material to view detailed engineering properties including material description, applicable standards, operating temperature and key mechanical characteristics.
Stainless steel inner rings provide excellent corrosion resistance and mechanical stability for spiral wound gaskets operating in aggressive chemical, high-temperature and pressure applications. Common grades include SS304, SS316 and higher alloy stainless steels.
Carbon steel inner rings are widely used in general industrial applications where corrosion resistance requirements are moderate. They provide strong mechanical support and prevent gasket blowout in standard pressure services.
Duplex stainless steel inner rings combine high mechanical strength with excellent resistance to chloride stress corrosion cracking. They are selected for offshore, marine and chemical processing applications.
Nickel alloy inner rings are designed for extreme corrosion environments and high-temperature applications. They are commonly used with spiral wound gaskets in chemical processing, petrochemical and aerospace industries.
Spiral wound gasket inner rings are selected across industries requiring reliable buckling support and erosion resistance under demanding pressure, temperature and flow conditions.
Pipeline flanges, separators, valves, compressors, offshore platforms and pressure vessels.
Reactors, heat exchangers, storage tanks, pumps and process piping systems.
High pressure and high temperature process equipment requiring reliable buckling support.
Steam lines, turbines, condensers, boilers and auxiliary piping systems.
Saltwater piping, desalination plants and offshore equipment.
High purity production equipment, clean piping and sanitary processing systems.
Provides internal support that prevents the winding from buckling under compression.
Protects the winding from erosion and turbulence caused by high-velocity process flow.
Selected to match the winding, filler and process media for a consistent, reliable seal.
Available according to ASTM, ASME, EN, DIN and JIS material specifications.
The inner ring provides internal support that prevents the gasket winding from buckling under compression and protects it from erosion caused by high-velocity process flow.
Stainless steel inner rings, typically SS304 or SS316, are the most widely used because they provide an excellent balance of corrosion resistance, mechanical strength and cost.
Nickel alloy inner rings are recommended for extreme corrosion or high-temperature environments, while titanium inner rings are preferred for marine and seawater applications requiring excellent chloride resistance.
