Product Detail
Product Introduction
Titanium heat exchanger tube is selected for corrosive process fluids and cooling media where tube material, wall thickness, cleanliness, fabrication route and inspection must match the exchanger design. Supply is reviewed against the project datasheet rather than assumed from alloy grade alone.
Product Specifications
| Product | Titanium Heat Exchanger Tube | Grade | Titanium Grade 2, Grade 7 or Grade 12 |
|---|---|---|---|
| Standard | ASTM B338 / ASME SB338 commonly covers seamless and welded titanium-alloy tubes intended for condensers and heat exchangers. Project, code and equipment datasheet requirements control grade, dimensions, fabrication and supplementary tests. | Size & Form | Round seamless or welded exchanger tube; OD, wall thickness, length and tube-end preparation by RFQ |
| Tolerance | ASTM B338 / ASME SB338 or project-defined OD, wall, length, straightness and end tolerances | Supply Condition | Straight lengths, clean and capped, with end protection and bundle or export-case packing |
| Inspection | MTC review, OD and wall measurement, length and straightness, surface and bore cleanliness, tube-end inspection, heat treatment records where applicable, specified NDT or pressure testing and heat/lot traceability. | Documents | MTC, heat/lot traceability and agreed inspection reports |

FAQ
Which titanium grade is used for heat exchanger tubes?
Grade selection depends on medium, temperature, pressure and corrosion conditions. Grade 2 is common, while Grade 7 or Grade 12 may be considered for more demanding qualified service.
Are seamless and welded tubes both available?
Both may be supplied when permitted by the applicable specification and project datasheet. The order must state the accepted manufacturing route.
What testing should an RFQ define?
State required dimensional inspection, eddy-current or ultrasonic testing, hydrostatic or pneumatic testing and any flattening, flaring or cleanliness acceptance.
