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. It provides strong mechanical performance, allowing for the construction of pressure vessels and heat exchangers without excessive material thickness.

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
