Applications

Super Duplex Pipe Fittings are widely used in demanding industries where high strength and excellent resistance to corrosion are required. Major applications include:

  • Oil & Gas Industry: Used in process piping, pipelines, offshore platforms, and fluid-transfer systems.
  • Offshore Industry: Suitable for seawater-exposed piping, production facilities, and offshore processing systems.
  • Petrochemical Industry: Used in process piping and equipment connections exposed to aggressive fluids.
  • Chemical Processing: Suitable for piping systems handling corrosive chemicals and process media.
  • Marine Industry: Used in selected seawater, cooling-water, and marine piping applications.
  • Desalination Plants: Applied in seawater intake, reverse-osmosis, and brine-handling systems.
  • Power Generation: Used in cooling-water, utility, and process piping systems.
  • Water Treatment: Suitable for corrosive water and wastewater treatment systems.
  • Pulp & Paper Industry: Used in selected process piping applications involving corrosive chemicals.
  • General Engineering: Used in industrial equipment, fabricated piping assemblies, and specialized fluid-handling systems.

Benefits

Super Duplex Pipe Fittings offer several advantages for demanding industrial piping systems:

  • High Mechanical Strength: Provides higher strength than many conventional austenitic stainless-steel grades.
  • Excellent Corrosion Resistance: Performs well in many aggressive and corrosive environments.
  • High Pitting Resistance: Suitable for applications exposed to chloride-containing environments.
  • Crevice Corrosion Resistance: Provides good resistance to localized corrosion when the appropriate grade is selected.
  • Stress-Corrosion Cracking Resistance: Offers good resistance to chloride stress-corrosion cracking.
  • Excellent Durability: Suitable material selection can provide long service life under demanding operating conditions.
  • Good Weldability: Can be welded using qualified procedures appropriate for the selected super duplex grade.
  • Wide Size & Configuration Range: Available in elbows, tees, reducers, caps, crosses, and stub ends in various sizes and schedules.
  • Reduced Maintenance Potential: Good corrosion resistance can help reduce corrosion-related maintenance in suitable applications.
  • Versatile Industrial Use: Suitable for oil & gas, offshore, petrochemical, chemical, marine, desalination, power, and water-treatment applications.
