Straight, U-Bent & Finned Tube Range
TiAlloy supplies three principal tube forms for heat exchangers, condensers and related thermal equipment: straight tubes for conventional bundles, U-bent tubes for return-flow bundle designs, and finned tubes for applications requiring additional external heat-transfer surface.
Product Path / Straight Length
Straight Heat Exchanger & Condenser Tubes
Straight tubes are supplied for shell-and-tube heat exchangers, surface condensers, coolers, evaporators and replacement tube bundles. Procurement normally defines material, product standard, outside diameter, wall thickness, fixed or random length, dimensional tolerance, surface condition and inspection scope.

Product Path / Return-Flow Bundle
U-Bent Heat Exchanger Tubes
U-bent tubes are prepared for exchanger and condenser bundles where both tube ends terminate at the same tubesheet. The purchase specification should define straight-leg length, bend radius, tangent points, tube dimensions and any project requirements for bend geometry, heat treatment, cleanliness, inspection and packing.

Product Path / Extended Surface
Finned Tubes for Heat Transfer Service
Finned tubes increase external heat-transfer surface where the thermal design calls for an extended-surface tube. Base-tube material, fin material, fin geometry, outside diameter, wall thickness, finished length and attachment method should be specified according to the exchanger, cooler or process duty.

Heat Exchanger Duty / Condenser Service / Equipment Selection
Heat Exchanger & Condenser Duty Map
The equipment duty defines the questions that come before material selection. Cooling medium, process chemistry, temperature, pressure, phase change, fouling and corrosion exposure should be understood before the tube grade and product specification are finalized.
Equipment First
Start with the thermal duty, not only the alloy.
A condenser, seawater cooler, process exchanger, evaporator and LNG vaporizer can place very different demands on the same nominal tube size.
Process Side
Fluid chemistry, temperature, pressure, phase condition and deposit tendency.
Cooling Side
Water chemistry, chlorides, temperature, flow conditions and fouling exposure.
Condensing Service
Surface Condenser
Surface condenser tubes separate the condensing vapor from the cooling medium. Tube selection should reflect both sides of the exchanger rather than the cooling-water environment alone.
Selection Focus
Cooling water · Vacuum duty · Chemistry · Fouling
Power Generation
Turbine Condenser
Steam turbine condenser tubes operate within large tube bundles where cooling-water conditions, steam-side cleanliness and the mechanical environment of the bundle all influence the tube specification.
Selection Focus
Steam cycle · Cooling water · Bundle duty · Vibration
Process Heating / Cooling
Process Exchanger
Process heat exchanger tubes may handle heating, cooling, condensing or partial phase-change duty. Fluid chemistry, operating temperature, pressure and cleaning conditions should be defined with the RFQ.
Selection Focus
Chemistry · Temperature · Pressure · Cleaning
Chloride Service
Seawater Cooler
Seawater cooler tubes work with natural or treated seawater as the cooling medium. Chloride exposure, water temperature, flow conditions and deposits are central inputs for tube-material selection.
Selection Focus
Chlorides · Temperature · Flow · Deposits
Phase Change
Evaporator
Evaporator tubes can see changing process concentration as liquid is boiled or concentrated. The fluid chemistry, operating temperature, scaling tendency and cleaning method should therefore be considered together.
Selection Focus
Concentration · Boiling · Scaling · Corrosion
Cryogenic Duty
LNG Vaporizer
LNG vaporizer tubing must be matched to the actual vaporizer design, cryogenic duty and warm-side medium. Systems using seawater also introduce a significant corrosion and chloride-selection requirement.
Selection Focus
Cryogenic duty · Seawater · Chlorides · Design
Define the equipment duty before selecting the tube material.
For a heat exchanger tube or condenser tube enquiry, identify the equipment type, process medium, cooling medium, operating temperature and pressure, and any known corrosion or fouling conditions before finalizing the alloy.
DUTY → TUBE Equipment Routing
Move from equipment duty to material selection
Surface condenser, turbine condenser, process exchanger, seawater cooler, evaporator and LNG vaporizer duties can require different tube materials and supply conditions.
Heat Exchanger Tube Materials / Condenser Tube Alloy Selection
Material Selection by Service
Heat exchanger and condenser tube material selection begins with the process and cooling-side conditions. Chloride level, temperature, pressure, oxidizing or reducing chemistry, fouling, velocity and fabrication requirements can change the appropriate alloy family.
Service first. Grade second.
TiAlloy reviews heat exchanger tube and condenser tube materials against the actual duty rather than treating one alloy as the universal choice for every exchanger.

Dimensional Review Bundle Fit-Up Inputs
Outside Diameter
OD tolerance becomes important where tubes pass through tubesheets and baffles.
Wall Thickness
Nominal and minimum-wall requirements should follow the ordered specification.
Fixed Length
State finished length and tolerance where tube preparation must match bundle geometry.
Straightness
Long straight tubes may require project-defined straightness control for assembly.
Size capability depends on material and manufacturing route.
The stainless heat exchanger tube ranges above are stated as TiAlloy supply capability. Titanium and nickel alloy tube dimensions should be confirmed against the selected alloy, product standard, seamless or welded route, required length and inspection scope rather than assuming the same stainless dimensional envelope.

Heat Exchanger Tube Manufacturing / Tube Mill Process
Manufacturing & Heat Treatment
Heat exchanger and condenser tube production combines dimensional reduction, forming, welding where applicable, heat treatment and final dimensional correction according to the selected material and product specification.
Seamless Tube Route
Dimensional Reduction
Cold rolling or pilgering reduces tube diameter and wall thickness while developing the dimensional condition required for subsequent processing.
OD / WT Control
Cold-Drawn Tube Processing
Cold drawing is used for applicable tube routes to reach ordered OD, wall thickness and dimensional consistency before final heat treatment and sizing.
Where Applicable
Welded Tube Production
Welded tubing is produced where the material, product standard and project specification permit a welded heat exchanger or condenser tube route.
Material Condition
Solution Heat Treatment
Solution annealing is applied where required by the alloy, product standard and ordered delivery condition after forming or cold-working operations.
Clean Bright Finish
Bright-Annealed Tube
Bright annealing is available for applicable grades and product conditions where a clean, bright tube surface is required by the purchase specification.
Bundle Fit-Up
Final Straightness Control
Straightening and final dimensional correction support long-tube handling, tubesheet insertion and exchanger bundle assembly requirements.
Manufacturing Logic Route Depends on Tube Construction
Seamless / Cold-Finished
Cold rolling or pilgering and cold drawing may be combined with intermediate or final heat treatment according to the alloy, starting dimensions and required finished tube.
Welded / Cold-Worked Where Required
Forming and welding establish the welded tube route. Heat treatment, sizing, straightening or additional cold work are applied according to the ordered specification.
Cold Rolling / Pilgering → Cold Drawing → Welding Where Applicable → Solution / Bright Annealing → Straightening
The images show available manufacturing processes, not one mandatory sequence.
Not every heat exchanger or condenser tube passes through every operation shown above. The actual manufacturing route depends on material grade, seamless or welded construction, dimensions, final condition, product standard and ordered inspection requirements.

Need additional external heat-transfer surface?
The next section covers low-fin and other finned tube constructions for exchanger and cooler service.
Finned Heat Exchanger Tubes / Low Fin Tubes / Extended Surface Tubes
Finned Tube Heat Transfer Solutions
Finned tubes increase external heat-transfer surface where the exchanger or cooler design requires more surface area than a plain tube provides. Fin construction should be selected together with the base tube material, fin material, operating temperature, environment and thermal duty.
Finned Tube Specification
Base tube, fin construction and finished geometry must be specified together.
A finned heat exchanger tube RFQ should identify the base tube alloy and standard separately from the fin material and fin construction. Finished tube length, finned length, bare ends and dimensional details are then matched to the exchanger or cooler design.

Heat Exchanger Tube Surface / Condenser Tube Cleanliness
Surface, Cleanliness & Tube Condition
Tube surface condition affects inspection, fabrication, cleanliness and service preparation. Bright annealed, pickled and other specified finishes should be matched to the alloy, manufacturing route and exchanger requirement.
Surface Is Part of the Tube Specification
OD appearance alone does not define exchanger tube condition.
Heat exchanger and condenser tube orders may need separate requirements for outside surface, inside surface, cleanliness, roughness and end protection. These conditions should be defined where they affect fabrication, inspection or service.
Outside Diameter
OD condition should be consistent with the material, product standard, heat treatment and final surface requirement.
Inside Diameter
Internal scale, residue, oil, loose particles or other contamination can be restricted where exchanger fabrication or service cleanliness requires it.
Roughness
Where surface roughness is critical, state the required Ra value, measurement location and whether the requirement applies to OD, ID or both.

Heat Exchanger & Condenser Tube FAQ
Procurement Questions
Short answers to the questions most often raised before specifying straight, U-bent, finned, replacement and condenser tubes.
What information is needed to quote heat exchanger or condenser tubes?
Provide the tube type, equipment or application, material grade, product standard, OD, wall thickness, finished length, quantity, surface condition, inspection, documentation and destination. U-bent and finned tubes require additional geometry or fin details.
Does TiAlloy supply titanium, stainless steel and nickel alloy heat exchanger tubes?
TiAlloy supplies heat exchanger and condenser tube products in titanium, stainless steel, duplex and selected nickel alloys. Exact availability depends on grade, standard, tube form, dimensions and manufacturing route.
Which standards are commonly used for heat exchanger and condenser tubes?
Common routes include ASTM B338 for titanium, ASTM A213 for seamless stainless heat exchanger tubes, ASTM A249 for welded stainless tubes, ASTM A789 for duplex, ASTM B163 for selected nickel-alloy condenser tubes and grade-specific specifications such as ASTM B444 for Alloy 625. The final standard must match the grade and product form.
Can TiAlloy supply U-bent heat exchanger tubes?
Send material, standard, OD, wall thickness, centerline radius, leg length, quantity by radius, bend tolerances, heat-treatment requirements and inspection scope. Feasibility is confirmed against the approved geometry.
Can TiAlloy supply finned heat exchanger tubes?
Finned tube enquiries can include low-fin, mechanically attached, embedded, extruded or welded helical constructions where applicable. State the base tube, fin material, fin type, geometry, finned length, bare ends and service duty.
What inspection and NDT can be specified for exchanger tubes?
Depending on the product standard and project ITP, inspection can include dimensional checks, ET, UT, hydrostatic testing, tensile, hardness, flattening, flaring, PMI and other specified examinations. Test frequency and acceptance criteria are order-specific.
Can tubes be supplied to fixed length for condenser retubing?
Yes, where the required dimensions and tolerances are defined. For retubing or shutdown supply, send the existing tube specification, replacement length, quantity, inspection requirements and required-on-site date.
What surface conditions are available for heat exchanger tubes?
Surface condition depends on alloy, manufacturing route and product specification. Bright annealed, pickled and other specified finishes may be available. State any required Ra, ID / OD condition, internal cleanliness or end protection with the RFQ.
What documents can be supplied with heat exchanger and condenser tubes?
Documentation can include MTCs, heat or lot traceability, dimensional reports, NDT records, PMI reports and project-specific inspection records where required. EN 10204 Type 3.1, Type 3.2 or third-party witness requirements should be stated before quotation when applicable.
Does TiAlloy manufacture complete heat exchangers or condensers?
This page covers tube products and related processing for exchanger and condenser fabrication, replacement and retubing projects. Complete exchanger thermal design or finished-equipment supply is not included unless separately agreed.
