Product Overview

The ASME SB338 standard governs the material specifications for titanium tubes and titanium alloy tubes used in heat exchangers and other high-pressure applications. The "SB" designation indicates that the material is for boiler and pressure vessel applications.

The Grade 7 (Gr. 7) designation refers to a specific titanium alloy with 0.2% palladium for enhanced corrosion resistance. This alloy is lighter than steel, which is particularly advantageous in aerospace, marine, and other weight-sensitive industries.
Chemical Composition
  • Titanium Grade 7 (Ti-0.2Pd) is an alloy primarily composed of titanium with a small percentage of palladium (0.12-0.25%). This alloy offers enhanced corrosion resistance in aggressive environments.
  • Titanium (Ti) provides excellent strength-to-weight ratio, outstanding corrosion resistance, and high-temperature performance.
  • Palladium (Pd) improves resistance to general corrosion, particularly in acidic environments.
Manufacturing and Processing
  • Cold Working: Typically processed into tubes, sheets, and plates through extrusion, rolling, or drawing.
  • Heat Treatment: Annealing or solution heat treatment can improve ductility and strength in specific applications.
  • Welding: Weldable using TIG processes, with palladium enhancing weldability compared to other titanium grades.
  • Surface Finish: Smooth surfaces preferred for heat exchanger applications to enhance efficiency and reduce fouling.
Key Applications
  • Seawater heat exchangers for ships, offshore oil rigs, and desalination plants
  • Cooling systems for naval vessels and submarines
  • Offshore oil and gas platform heat exchangers
  • Petrochemical refining cooling systems
  • Reverse osmosis (RO) desalination unit cooling systems
