Straight seamless or welded titanium tube bent into spiral or helical coil form -- for compact heat exchangers, chillers and condensers where footprint is constrained.
| Parameter | Supply Reference | Custom Supply Range |
|---|---|---|
| Base Tube Outer Diameter | Typically uses seamless tube in the 10 – 273 mm range or welded tube in the 6.35 – 610 mm range | To Be Confirmed Against Product Requirements |
| Coil Diameter | Per customer drawing and heat exchanger design | Custom coil diameters per order |
| Coil Pitch | Per customer drawing -- center-to-center spacing between adjacent coil turns | Custom pitch per order |
| Total Length | Per customer design requirement | Custom lengths per order |
| Minimum Bend Radius | Dependent on base tube OD, wall thickness and grade | Confirmed against base tube specification |
Coiled tube grade is determined by the base tube grade used as starting material.
Grade 1 (CP Ti), Grade 2 (CP Ti), partial Grade 5 (Ti-6Al-4V). Base tube is available from stock; coil bending performed to order.
Grade 3, Grade 4, Grade 7, Grade 9, Grade 12 and other grades. Base tube production and coil bending both coordinated per order.
Coiled titanium tubes are secondarily formed from straight seamless or welded tubes. The relevant standards therefore start with the base tube standard, and bending is evaluated against the project specification and forming requirements.
For the base straight round tube, ASTM B338 / B337 apply as industry references for the underlying seamless or welded round tube. The coiled geometry itself is not directly covered by these standards and should be evaluated against the project specification, minimum bend radius requirements, flattening limits and inspection criteria agreed for the order.
Coil-form titanium tubing for heat exchangers where the spiral geometry enables more heat-transfer area within a given footprint.
Titanium coil bundles for process chillers, refrigeration condensers and specialty cooling systems.
Custom coil configurations for research reactors, sample coolers, liquid-vapor separators and specialty process loops.
Coiled titanium tube refers to tubular product that has been bent into a spiral coil shape for heat exchanger or process equipment use. Coiled titanium wire refers to solid titanium wire (not hollow tube) supplied wound into loose coils for downstream rewinding, welding or weaving. These are two different product categories.
Bending feasibility depends on the base tube grade, wall thickness-to-OD ratio and required coil diameter and pitch. Thin-walled tubes and tight coil diameters present higher forming risk including wrinkling, ovality and wall thinning. Minimum bend radius and feasibility should be confirmed per inquiry before quotation.
Straight base tubes may be available from stock (Grade 1, Grade 2, partial Grade 5 in common seamless or welded sizes). Coil bending itself is performed to order. The finished coiled configuration is not maintained as regular stock.
The nominal wall thickness of the base tube is specified by the manufacturer. During bending, some localized wall thinning can occur at the outer bend and some thickening at the inner bend. The final wall thickness at critical bend locations should be confirmed against the project specification and inspected after forming.
To receive an accurate quotation, please provide as many of the following details as possible: base tube OD, wall thickness, grade, coil diameter, coil pitch, number of turns, total finished length and end preparation. If you have a drawing or specification sheet showing the coil geometry, please share it with our sales team.
