Features
- Manufactured to ASTM B338 for seamless and welded titanium and titanium alloy tubes intended for condenser and heat exchanger service.
- Available in Grade 2, Grade 5, Grade 7, Grade 9, and Grade 12.
- Grade 2 offers excellent corrosion resistance and good formability, making it a common choice for chemical and seawater-exposed service.
- Grade 5 (Ti-6Al-4V) provides much higher strength than commercially pure titanium grades and is widely used where strength-to-weight performance matters.
- Grade 7 (Ti-0.2Pd) provides improved corrosion resistance, especially in chloride-bearing and reducing environments.
- Grade 9 (Ti-3Al-2.5V) combines good corrosion resistance with higher strength and good fabricability.
- Grade 12 (Ti-0.3Mo-0.8Ni) offers improved resistance to reducing solutions and crevice corrosion, especially in chemical service.
- Supplied in straight tubes, U-tubes, and tube coils, with sizes suitable for industrial heat-transfer systems.
