What Is Titanium Welded Tube?
Titanium welded tube is produced from titanium strip or coil through forming, welding, sizing and heat treatment processes. It is commonly reviewed where corrosion resistance, thin wall thickness, dimensional consistency and cost efficiency are required.
Compared with titanium seamless tube, titanium welded tube is often suitable for heat exchangers, condensers and evaporators, cooling systems, heating elements, chemical equipment and selected exhaust applications when the working condition and customer specification allow welded tubing.
The correct tube choice depends on titanium grade, OD, wall thickness, pressure level, weld integrity, working medium, corrosion condition, forming requirement, tube sheet connection, inspection scope and end-user approval.
Practical Purchasing Reasons
- Thin wall thickness and stable wall control are required.
- The project needs corrosion resistance in seawater, chloride-rich water or chemical environments.
