ASME SB338 UNS R50400 GRADE 2 UNALLOYED TITANIUM SEAMLESS TUBE
An SB338 R50400 tube is a seamless or welded tube made from the aerospace-grade titanium alloy Ti 6Al-4V ELI, manufactured to meet strict standards for pressure and corrosion service, primarily in heat exchangers and condensers.

Applications:
Because of these advantages, SB338 R50400 tubes are used in highly demanding and corrosive environments:
Shell-and-Tube Heat Exchangers & Condensers in:
Offshore Oil & Gas Platforms (seawater cooling)
Marine and Naval Ships
Desalination Plants (Multi-Stage Flash and MED plants)
Power Plant Surface Condensers (especially coastal plants)
Chemical and Petrochemical Processing
Airframe and Aerospace Components
Cryogenic and Deep-Sea Applications
High-Performance Automotive and Racing
The main advantage of SB338 R50400 tube is that it provides an unmatched combination of extreme corrosion resistance (especially to seawater), high strength, light weight, and exceptional fracture toughness (due to its ELI grade) in a standardized, reliable product form. It is a premium material specified where performance, safety, and longevity in harsh environments are paramount, justifying its higher initial cost compared to materials like copper-nickel or stainless steels.
