ASTM B338 Gr2 Gr9 Titanium Seamless Tube for heat exchangers
Leave a message
What is ASTM B338 material?
ASTM B338 titanium seamless tubing is a type of unalloyed or alloyed titanium tubing manufactured to ASTM International standards. It is produced by cold shrinking or cold drawing a hollow billet, resulting in a "seamless" construction without welds. This tubing, meeting the requirements of ASTM B338, is specifically designed for high-performance applications such as condensers, evaporators, and heat exchangers.
ASTM B338 Gr2 and Gr9 titanium seamless tubing is used in heat exchangers due to its excellent strength-to-weight ratio and outstanding corrosion resistance in harsh environments such as seawater. Grade 2 is an industrial-grade, unalloyed titanium, while Grade 9 is a stronger titanium alloy (3% aluminum, 2.5% vanadium). These tubes are critical components in a variety of heat exchange equipment, including condensers, evaporators, and coolers, especially when high performance is required in corrosive media.
