Large-diameter High-precision Seamless Titanium Tubes for Marine Aerospace

Large-diameter high-precision seamless titanium tubes are manufactured through advanced extrusion and precision rolling processes, delivering a true seamless structure with excellent dimensional accuracy.
See also our full range of titanium tubes and pipes for industrial, marine, and aerospace applications.

Designed for demanding environments, these tubes combine large outer diameters (up to Ø325 mm), tight tolerances, and flexible wall thickness options, making them ideal for marine, aerospace, and critical engineering systems.

Key Features of large diameter high precision seamless titanium tube

  • Seamless structure – No weld seam, improved pressure resistance and fatigue performance

  • Large diameter – Outer diameter up to Ø325 mm, larger sizes available upon request

  • High dimensional precision – Excellent control of roundness, straightness, and wall thickness uniformity

  • Thin-wall & thick-wall – Optimized for lightweight designs or high-pressure applications

  • Excellent corrosion resistance – Suitable for seawater, chloride, and harsh chemical environments

  • High strength-to-weight ratio – Ideal for aerospace and weight-sensitive systems
