Round titanium tubes with periodic external corrugations or internal rifling -- increasing turbulence and heat-transfer performance for process condensers and enhanced heat exchangers.
| Parameter | Supply Reference | Custom Supply Range |
|---|---|---|
| Base Tube Outer Diameter | Uses seamless tube base (10 – 273 mm) or welded tube base (6.35 – 610 mm) | To Be Confirmed Against Product Requirements |
| Corrugation / Rifling Pattern | Per heat exchanger design: pitch, depth, wave shape, internal vs external | Custom pattern per specification |
| Length | Per heat exchanger design requirement | Custom lengths per order |
| Forming Route | Secondary forming of smooth base tube | Confirmed against pattern and base tube |
Corrugated or rifled tube grade is determined by the base smooth round tube used as starting material.
Grade 1 (CP Ti), Grade 2 (CP Ti), partial Grade 5 (Ti-6Al-4V). Base tube available from stock; secondary forming performed to order.
Grade 3, Grade 4, Grade 7, Grade 9, Grade 12 and other grades. Both base tube production and secondary forming coordinated per order.
Corrugated and rifled titanium tubes are secondarily formed from smooth round seamless or welded tubes. The relevant base tube standards are the same round-tube specifications (ASTM B338 / B337) that apply to smooth round titanium tubes. The corrugated or rifled surface features themselves are not directly covered by these standards and should be evaluated against the heat exchanger design specification, forming feasibility and inspection criteria agreed for the order.
Titanium corrugated and rifled tubes for heat exchangers where enhanced heat transfer is required to reduce equipment size or improve performance.
Enhanced-performance condenser and evaporator tubing in desalination, power generation and chemical processing systems.
Corrugated titanium tube bundles for corrosive chemical process heat exchange where both corrosion resistance and enhanced heat transfer are required.
Corrugated titanium tubes have periodic surface features (wave-like or folded) on the outside of the tube wall. Rifled titanium tubes have internal spiral grooves cut or rolled into the inside wall of the tube. Both types serve to increase fluid turbulence and heat transfer. Some designs combine both features.
ASTM B338 and B337 are standard specifications for smooth round titanium tubes. Corrugated and rifled titanium tubes are secondarily formed from smooth base tubes and the surface features themselves are not directly covered by these standards. The base tube must meet its applicable standard; the formed surface features are evaluated against the heat exchanger design specification and order requirements.
Smooth base tubes may be available from stock (Grade 1, Grade 2, partial Grade 5 in common sizes). Corrugation or rifling forming itself is performed to order. The finished corrugated or rifled configuration is not maintained as regular stock.
Forming corrugations or rifling introduces localized wall thinning and changes the tube's pressure capability. The forming process and the final tube pressure rating must be reviewed together. Feasibility and pressure capability are confirmed against the base tube OD, wall thickness, grade and specific corrugation or rifling pattern.
To receive an accurate quotation, please provide as many of the following details as possible: base tube OD, wall thickness, grade, corrugation or rifling pattern (pitch, depth, geometry), required length and intended heat exchanger application. If you have a drawing or pattern specification, please share it with our sales team.
