Titanium tube bundles for shell-and-tube heat exchangers, condensers and specialty exchanger designs -- supplying straight seamless tubes as the most common configuration.
The most common configuration is straight seamless round tube. Below are the reference parameters for this primary configuration.
| Parameter | Standard / Industry Reference Range | Custom Supply Range | Regular Stock Range |
|---|---|---|---|
| Outer Diameter (OD) | Common shell-and-tube exchanger ODs within the 10 – 273 mm seamless range | To Be Confirmed Against Product Requirements | Common seamless HX tube ODs from stock |
| Wall Thickness | Default Sch 40 reference | Final wall thickness confirmed against OD, pressure class and order requirements | Sch 40 for common ODs where stocked |
| Tube Length | Per exchanger design requirement | Custom lengths and end preparation per order | Standard lengths per stocked sizes |
| End Preparation | Plain cut standard | Expanded ends, beveled ends or other end prep per specification | Plain cut plain ends |
| Tube Configuration | Straight seamless tube (primary configuration) | Enhanced-surface, welded or coiled configurations for specialized designs | Straight seamless |
Grade selection for heat exchanger duty is driven primarily by the fluid environment and operating pressure.
Grade 2 is the standard titanium grade for heat exchanger tubes. It provides excellent corrosion resistance against seawater, brackish water, dilute acids and most chemical process fluids. Available from stock for common sizes.
Lower oxygen and iron content than Grade 2, offering slightly better corrosion resistance in certain environments. Available from stock in common sizes.
Higher-strength titanium alloy selected where higher operating pressure or structural load requires alloy strength. Requires technical review for heat exchanger feasibility.
Grade 7 (Ti-0.15Pd) for improved corrosion resistance in certain reducing acid environments, Grade 9 (Ti-3Al-2.5V) and other specialty grades. Availability reviewed per order.
ASTM B338 / B338M — Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers. This is the primary round-tube standard for heat exchanger and condenser duty, covering both seamless and welded round titanium tubes. For straight seamless heat exchanger tubes, ASTM B338 is the most directly applicable reference.
ASTM B337 / B337M — Standard Specification for Seamless and Welded Titanium and Titanium Alloy Pipe. Applies to general process piping service.
These standards apply to round titanium tubes. Enhanced-surface (corrugated, rifled), non-round (flat, oval, square) and coiled configurations are evaluated against their specific product form and order specification.
Titanium heat exchanger tubes are selected where the fluid environment demands titanium's corrosion resistance and the exchanger design requires reliable pressure containment.
Titanium tube bundles for shell-and-tube exchangers serving corrosive process fluids, seawater cooling, brackish water heating and chemical process heat exchange.
Titanium condenser tubes in thermal power plants, combined-cycle power and industrial power generation systems where seawater or brackish water is used as coolant.
Titanium tubing in MED (multi-effect distillation) desalination plant condenser and evaporator bundles.
Titanium heat exchanger tubing in FGD systems where the exhaust gas environment is highly corrosive.
For heat exchanger tube orders, documentation typically covers both the tube material and the inspection tests required by the exchanger specification.
Grade 2 (commercially pure titanium) is by far the most common grade for heat exchanger and condenser tubes. It provides excellent corrosion resistance against seawater, brackish water, dilute acids and most chemical process fluids at an economical price. Grade 1 is used where slightly better corrosion resistance is required. Grade 5 and other alloy grades are used when higher strength is needed.
The primary configuration for heat exchanger duty is straight seamless round titanium tube. The confirmed OD range for seamless titanium tubes is 10 – 273 mm. Not every diameter within this range is stocked as regular stock. Common heat exchanger tube ODs are available from mill inventory.
Yes. ASTM B338 / B338M is the primary standard specification for seamless and welded round titanium and titanium alloy tubes for condensers and heat exchangers. This standard directly applies to the straight seamless round tube configuration that is the most common heat exchanger tube form.
Yes. Corrugated, rifled and other enhanced-surface titanium tubes can be supplied for heat exchanger designs requiring improved heat-transfer performance. Feasibility depends on the OD, wall thickness, grade and specific surface pattern. Please provide the exchanger design requirements for confirmation.
To receive an accurate quotation, please provide as many of the following details as possible: tube OD, wall thickness or schedule, grade, tube length, quantity, end preparation and exchanger type. For enhanced-surface, coiled or custom configurations, please include the pattern or geometry specification. If you have a tube sheet drawing or exchanger specification sheet, please share it with our sales team.
