ASME SB338 Grade 2 UNS R50400 Titanium Seamless Tube, Corrosion Resistant For Chemical, Marine And Heat Exchanger

ASME SB338 is a standard specification covering seamless and welded titanium & titanium alloy tubes intended for condensers and heat exchangers. Though originally developed for heat exchanger service, tubes manufactured to this standard are widely adopted across many other critical industrial applications.

Grade 2 is unalloyed commercially pure titanium, featuring outstanding corrosion resistance, good ductility and moderate mechanical strength.

UNS R50400 is the Unified Numbering System designation uniquely identifying this material composition, which directly corresponds to ASTM Grade 2 titanium.

Applications

Heat Exchangers & Condensers: The primary application in the standard's title. Used in chemical processing, power generation (especially offshore platforms), and desalination plants.
Chemical & Petrochemical Processing: For piping systems, reactors, and vessels handling corrosive chemicals.
Marine & Offshore: For seawater piping, ballast systems, and other components exposed to saltwater.
Aerospace: For hydraulic and pneumatic systems, and airframe components where weight savings are critical.
Medical & Pharmaceutical: For implants, surgical instruments, and processing equipment due to its biocompatibility.
