Product Introduction

Grade 2 seamless titanium tube is commonly used in shell-and-tube heat exchangers, condensers, evaporators, and seawater cooling equipment where corrosion resistance and stable heat-transfer performance are required.
Tube outside diameter, wall thickness, straightness, and internal surface condition are important for tube expansion, tube-sheet assembly, cleaning, and long-term fluid service.
ASTM B338 tubing can be supplied in fixed lengths with surface condition, tube-end preparation, testing, and documentation confirmed according to the equipment drawing and operating medium.

Package and delivery

Heat exchanger tubes are cleaned and separated by size, length, and material batch before packing. Tube ends can be protected to reduce contamination and impact damage during handling.
Long tubes are supported at suitable intervals inside the package to reduce bending, movement, and contact marks during transportation.
Wooden crates, internal spacers, protective wrapping, and end protection are selected according to tube dimensions, quantity, and shipping method.

FAQ

Q1: What grade of titanium tubing is typically used for heat exchangers?

A: In practical projects, Gr1 and Gr2 are the most common choices. The specific grade usually needs to be determined based on a comprehensive consideration of design pressure, tube sheet structure, and assembly method.

Gr1: Higher ductility, suitable for tube expansion or bending structures requiring high formability.
Gr2: Balances strength and formability, more commonly used in conventional industrial heat exchangers.

Q2: Are titanium tubes prone to cracking during expansion or welding processes?

A: Grade 2 titanium tube has practical formability and weldability. The risk of cracking or excessive springback can be reduced by confirming the annealed condition, wall thickness tolerance, expansion ratio, tooling, and welding procedure before fabrication.

Q3: Do titanium tubes require special surface treatment?

A: For most heat exchanger applications, pickled or bright annealed surfaces are sufficient. Internal cleanliness, surface condition, and compatibility with the working medium should be confirmed instead of applying unnecessary coatings.

Q4: Is it possible to customize non-standard size titanium tubes based on project requirements?

A: Yes. However, we need to confirm the design drawings, the medium of use, and the working temperature and pressure range to ensure that the dimensions and material specifications match the actual working conditions.

Q5: Can I order small trial batches?

A: Yes. Trial quantities can be reviewed according to the requested grade, dimensions, length, testing requirements, and current material availability.
