What makes Super Duplex coiled tubes superior to standard duplex stainless steel?

Super Duplex coiled tubes outperform standard duplex steels due to their enhanced chemical and mechanical composition:

  • High Chromium (24–26%): Provides excellent resistance to pitting and crevice corrosion.
  • High Molybdenum (3–5%): Increases resistance to localized corrosion, especially in seawater and chloride environments.
  • Higher Nitrogen (0.18–0.25%): Improves strength and resistance to stress corrosion cracking.
  • Superior Mechanical Strength: Yield strength of 520–550 MPa and tensile strength of 750–900 MPa.
  • Applications: Ideal for offshore platforms, chemical plants, heat exchangers, hydraulic lines, and instrumentation systems where corrosion and mechanical reliability are critical.
  • Precision Dimensions: Smooth OD and wall thickness for leak-proof connections.
  • Seamless and Welded Options: Provides flexibility for various hydraulic and instrumentation requirements.
  • High Pressure Resistance: Maintains structural integrity under extreme pressures.
  • Applications: Used in control lines, instrumentation, hydraulic machinery, and chemical injection systems.
