Seamless Titanium Tube for Industrial Heat Exchangers

Heat exchangers fail at the tube. Pitting. Erosion. Cracking. Once one tube goes, the whole unit comes down.

Seamless titanium tube for industrial heat exchangers stops that cycle. No weld seam to fail. No corrosion to thin the wall. No pitting from chlorides.

Shell and tube exchangers. Condensers. Coolers. Evaporators. Anywhere you move heat between fluids and need the tubes to last.

Welded tube has a seam. The weld is fine most of the time. But in a heat exchanger, thousands of tubes. Vibration. Thermal cycling. The seam is the weakest point.

Seamless tube starts as a solid billet. Pierced. Rolled. Drawn. No weld seam. No seam to crack. No seam to corrode.

For seamless titanium tube for industrial heat exchangers, you get uniform wall thickness. No weld zone with different grain structure. Better fatigue life. Safer.

Costs more than welded. But in a critical exchanger, seamless is the standard.

Grade 2 covers 80% of heat exchanger jobs. Seawater cooling. Chemical plant service. Fresh water.

Grade 12 for hot seawater. Above 50°C. Or tight tube-to-tubesheet joints where crevice corrosion is a risk.

Grade 7 for aggressive hot acids. Rare. Most buyers don't need it.

Seamless titanium tube for industrial heat exchangers is usually Grade 2. Ask for Grade 12 if your water is warm.

Dimensional range

Tolerance: OD ±0.08mm to ±0.15mm. Wall ±10%.

Power plants. Cooling water condensers. Thousands of seamless titanium tube for industrial heat exchangers in the hot well. Steam on shell side. Seawater inside the tubes.

• Chemical plants. Reactor coolers. Acid service. Grade 2 or Grade 7 depending on chemical.
• Desalination plants. Brine heaters. Grade 12 for hot brine. Tubes last years instead of months.
• Offshore platforms. Shell and tube coolers for produced water. Titanium doesn't care about chlorides.
• HVAC. Large chillers. Fresh water or seawater. Grade 2.

Every one of these exchangers had steel or copper-nickel tubes at some point. Every one of them switched to titanium.

Three reasons.

No corrosion allowance. Steel tubes need extra wall thickness. They rust from the inside out. Titanium doesn't. You can use thinner wall. Better heat transfer.

No pitting. Stainless tubes pit in stagnant seawater. Titanium doesn't. Lay up the exchanger for months? Fine. No surprise holes when you restart.

No tube sheet crevice issues. Tube-to-tubesheet joints can trap stagnant water. Grade 12 handles this. Grade 2 does okay.

Seamless titanium tube for industrial heat exchangers doesn't just last longer. It changes how you operate. Less worry. Less downtime.

Rolling titanium tubes into tube sheets is different from steel.

Titanium work-hardens. Use controlled rolling pressure. Too light and the tube leaks. Too heavy and you crack the tube.

Tube end preparation matters. Clean. Deburred. No scratches. Scratches become crack starters under rolling pressure.

Tube-to-tubesheet welding is common for critical service. Purge the tube side with argon. Weld inside the tube end or from the tubesheet face. Use matching filler. ERTi-2 for Grade 2.

For seamless titanium tube for industrial heat exchangers, we can supply tube ends pre-cleaned and capped. Ready for installation.

ASTM B338 requires:

• Hydrostatic pressure test. Every tube. No exceptions.
• Flattening test. Sample from each lot.
• Flaring test. Sample from each lot.
• Eddy current or ultrasonic NDT. Finds wall defects.
• We provide the reports. Heat number traceable. Full mill test reports.

If your exchanger needs third-party inspection (DNV, ABS, Lloyds), tell us. We arrange it.

Heat exchangers are expensive to replace. Tube failures shut down plants.

Seamless titanium tube for industrial heat exchangers stops the tube failures. No corrosion. No pitting. No weld seam to crack.

Grade 2 for most jobs. Grade 12 for hot seawater. Seamless for reliability.
