Shaanxi Chuanghui Daye Metal Material Co., Ltd. works out of Baoji, China. The plant sits there. From that site, Titanium Tube For Heat Exchanger ships to buyers in many countries. ASTM B337 and B338 are the standards production follows. Gr1, Gr2, Gr3, Gr4, Gr7, Gr9 and Gr12 make up the grade list. The team also cuts tubes to whatever size a customer asks for. Density of titanium comes to 4.51 g/cm³. The metal also grows an oxide film, and that film repairs itself. Seawater cannot hurt it. Nor can media that carry chloride. That film is why. The company's founder brings more than 30 years in the rare metal industry. Products go to over 50 countries.
One main job is why shell-and-tube heat exchangers need the tube. Surface condensers count on it too. Evaporators do the same. It keeps hot fluid away from cold fluid. Most tubes are made of commercially pure titanium. The usual pick is ASTM B338 Gr1 or Gr2. An alloy grade such as Gr7 is another way to go.
Oxygen meets titanium and a stable TiO2 film forms. That film clings tight to the surface. Scratch it and the film grows back, as long as oxygen is still around. Seawater and brine would cause pitting and crevice corrosion. This passive layer blocks most of it.
These tubes also go into U-tube bundles. Shell-and-tube units make use of them too. For the shell itself, solid titanium is one option. Carbon steel works as well. Titanium-lined explosive-bonded material does the job too. Heat moves from one fluid across to the other. The two never mix.

For a light part, titanium gives you plenty of strength. Density comes in at 4.51 g/cm³. Put it on the scales next to steel and you land at about 60%.
Copper moves heat better than this alloy does. Strength is what you get back. Thin walls turn into a real option. Most of them sit between 0.5 mm and 0.7 mm. Usually no corrosion allowance gets added. Heat has less distance to cross when the wall is thin. Get the design right and heat transfer comes close to Cu-Ni alloys.
The oxide layer does not move. Scale finds nothing to settle on. Corrosion products have no grip on the surface. Both stay lower, so the overall heat transfer coefficient (U value) usually holds steadier over time. In real plants, water quality still decides fouling. Flow velocity plays a part too. So does cleaning practice.
Plain tubes give out fast in seawater. Brine streams attack them the same way. So does acid. Built for heat exchanger duty, a titanium tube, Titanium Tube For Heat Exchanger, gets past several common failure points because of the metal itself.

Each size is produced to order. Want a price quote for a heat exchanger tube order? Send the outside diameter and the wall thickness. Let us know the length. Put the quantity in your message. The grade you need should be noted too. Another option: describe the medium, temperature, and flow velocity. Our team can recommend one.
Tubes from us ship to ASTM B337 and B338. On shell-and-tube and U-tube work, the bundle layout is where we start. Every tube is cut and sized to suit that drawing. When you send the inquiry, add a note on how you want the tubes packed.



Shaanxi Province is where the firm has its base, in the Baoji High-tech Development Zone. All over China, people know Baoji as the "Titanium Capital." Behind the company stands a founder with more than 30 years in the rare metal industry.
Titanium, tantalum, niobium, tungsten, molybdenum, zirconium and nickel all fall inside our range. Other non-ferrous and rare metal alloys are covered as well, and Titanium Tube For Heat Exchanger is one of them. Metallurgy is one field they go into. Electronics takes them too. Medical work uses them, and so does special steel. Need more than one material? Put them all on a single inquiry. Buyers in over 50 countries get supplied.

Q: What job does a titanium tube do inside a heat exchanger?
A: Its shape is a tube. Gr1, Gr2 or Gr7 is what most of them are made from. Through it, heat moves from a hot fluid to a cold one. Shell-and-tube exchangers rely on it. Condensers use it as well. So do evaporators.
Q: What grades and standards can you supply?
A: Gr1, Gr2, Gr3 and Gr4 are on the list. So are Gr7, Gr9 and Gr12. Two ASTM standards cover this tubing. One of them is B337. B338 is the other.
Q: Can I order custom sizes?
A: Yes. Send your diameter and wall thickness by email. Length and quantity should go in too. From there the team confirms what can be supplied.
Q: Copper moves heat better than titanium does. So why pick titanium?
A: This material works at thin walls. A 0.5 mm–0.7 mm wall holds up fine and no corrosion allowance is needed. Less thickness also means a shorter heat path. In a well-designed unit, overall performance can then get close to Cu-Ni alloys.
Q: Can it handle fast seawater flow?
A: Erosion-corrosion is a known weak spot in copper-nickel alloys. Titanium tolerates faster flow than those alloys can. Your design velocity still needs a check against the exchanger setup.
Q: How long will it last?
A: Four things decide how long a tube lasts: the medium, the temperature, the flow speed, and the design. For seawater and high-chloride duty, titanium is often the pick. Those conditions tend to corrode copper-nickel tubes. Stainless steel tubes act the same way. Send us your operating data. We will review it for your project.
