Flat or oval profile titanium tubes are non-round tubular products with a flattened (rectangular) or oval cross-section rather than a round cross-section. The non-round profile increases the surface-to-volume ratio compared to round tubes, enabling more heat-transfer area within a given volume -- a key requirement for compact heat exchanger and radiator designs. Flat and oval titanium tubes are produced by forming and welding titanium strip or by drawing through specialty shaped dies.

Supply is coordinated per inquiry against profile dimensions (width x height or major/minor axis), wall thickness, grade and length. The specific production route depends on the profile dimensions, wall thickness and required quantity.

Grades & Materials

RS

Regular Stock

Grade 1 (CP Ti) and Grade 2 (CP Ti) are the most common grades for flat and oval heat exchanger tubes. Availability depends on the specific profile dimensions.

CU

Custom Coordination

Grade 5 (Ti-6Al-4V) and other titanium or titanium alloy grades. Production feasibility reviewed per order against profile dimensions, wall thickness and forming route.

Standards & Technical References

Titanium flat and oval profile tubes have a non-round cross-section. ASTM B338 / B337 are standard specifications for round seamless and welded titanium tubes intended for heat exchanger and process piping service. These round-tube standards do not directly cover non-round profile tubes.

For flat and oval titanium tubes, applicable requirements are evaluated against the specific product form, production route and order specification. Tolerance requirements for profile dimensions, wall thickness and straightness are agreed for each order against the heat exchanger design requirements.

Typical Application Areas

HX

Compact Heat Exchangers

Flat and oval titanium tubes for compact heat exchanger designs where maximizing heat-transfer surface within a constrained volume is the primary objective.

RD

Radiators & Condensers

Titanium radiator tubing for marine, industrial and chemical applications where corrosion resistance and thermal performance are both critical.

CH

Chemical Process Coolers

Flat titanium tubes for compact process coolers and specialty heat exchange equipment in corrosive chemical environments.

Quality & Documentation

  • Material test certificates for titanium feedstock.
  • Dimensional inspection reports covering profile dimensions (width x height or major x minor), wall thickness uniformity and straightness.
  • Weld inspection documentation where applicable.
  • Heat or lot traceability records where available and applicable.

Frequently Asked Questions

Are flat titanium tubes covered by ASTM B338?

No. ASTM B338 and B337 are standard specifications for round seamless and welded titanium tubes intended for heat exchanger and process piping service. Flat and oval profile tubes have a non-round cross-section and are not directly covered by these round-tube standards. Applicable requirements are evaluated against the specific product form and order specification.

What is the difference between flat and oval titanium tubes?

Flat titanium tubes have a rectangular cross-section (width x height outer dimensions). Oval titanium tubes have an elliptical cross-section defined by major and minor axes. Both are non-round profile tubes designed to increase heat-transfer surface relative to round tubes.

Which grades are used for flat titanium tubes?

Grade 1 and Grade 2 titanium are the most common grades for flat and oval heat exchanger tubes. Grade 5 and other alloy grades can be used where higher mechanical strength or pressure capability is required, but feasibility must be reviewed per order against the profile dimensions and forming route.

Can flat titanium tubes be bent or coiled?

Yes, flat and oval titanium tubes can be bent and coiled depending on the grade, wall thickness and required bend geometry. Minimum bend radius and flattening limits are confirmed against the specific profile and grade. Feasibility should be reviewed per inquiry.
