Titanium U Tube | Grade 2 U-Shaped Tube for Heat Exchangers
TSM Technology supplies Grade 2 Titanium U Tubes for shell-and-tube heat exchangers, condensers, evaporators and seawater cooling systems. Manufactured from commercially pure titanium, our U-shaped tubes combine excellent corrosion resistance, good formability and reliable dimensional control for demanding heat transfer applications.
What Is a Titanium U Tube?
A Titanium U Tube, also called a titanium U-shaped tube or titanium U-bend tube, is a titanium tube formed into a U-shaped configuration for use primarily in shell-and-tube heat exchangers and condensers.
Unlike a straight tube, a U-tube configuration allows the tube to expand and contract as operating temperatures change. This makes U-tube designs particularly useful in heat exchanger systems where thermal expansion, corrosion resistance and long-term reliability are important.
Grade 2 Titanium is one of the most widely used commercially pure titanium grades for industrial heat exchanger tubes. It provides a practical balance of corrosion resistance, formability, mechanical properties and cost.

Why Use U Tubes in Heat Exchangers?
U-tube heat exchangers are widely selected for applications where temperature changes can create significant thermal expansion. The U-shaped tube configuration provides several practical engineering advantages.
Thermal Expansion Compensation
The U-shaped configuration allows the tube bundle to accommodate thermal expansion and contraction during heating and cooling cycles.
01
Corrosion Resistance
Titanium provides excellent resistance to seawater, chloride-containing environments and many industrial process media.
02
Compact Heat Exchanger Design
U-tube configurations can provide an efficient solution for shell-and- tube heat exchangers where compact and reliable tube arrangements are required.
03
Long Service Life
The corrosion resistance of titanium can help reduce tube replacement and maintenance requirements in suitable service environments.
