Titanium pipes and tubes are widely known for their exceptional strength-to-weight ratio, outstanding corrosion resistance, and superior performance in extreme environments. These grades are extensively used in aerospace, marine, chemical processing, medical, oil & gas, and power generation industries.

What Are Titanium Grade 1 / 7 / 9 / 23 Pipes & Tubes?

Titanium pipes and tubes are hollow cylindrical products manufactured from commercially pure titanium or titanium alloys. Each grade offers specific mechanical and corrosion-resistant properties tailored to different industrial applications.

Overview of Grades:

  • Titanium Grade 1 (UNS R50250): Commercially pure titanium with excellent corrosion resistance and maximum ductility.
  • Titanium Grade 7 (UNS R52400): Similar to Grade 2 but with added palladium for enhanced corrosion resistance in reducing acids.
  • Titanium Grade 9 (UNS R56320): Titanium alloy with aluminum and vanadium offering moderate strength and good weldability.
  • Titanium Grade 23 (UNS R56401 / Ti-6Al-4V ELI): Extra-low interstitial version of Grade 5 with superior fracture toughness and biocompatibility.

These titanium grades are selected based on strength requirements, corrosion exposure, weight considerations, and industry standards.
