Gr12 titanium welded tube with ASTM B862 standards is made of Grade 12 material (Ti-0.3Mo-0.8Ni). It is typically supplied in the annealed condition. We provide surface treatment such as polishing, and all finished tubes with 100% ultrasonic testing.
These tubes are made from titanium strip or plate and welded by advanced processes. The processes include tungsten inert gas (TIG) welding and laser welding under full argon shielding, ensuring high structural integrity and contaminant-free welds. Titanium tube welding must be made under the protection of high-purity argon (99.999%) to effectively shield both sides of the weld joint from oxidation.

We can supply the Gr12 titanium welded tube as outside diameter rangs from 26mm to 426mm with the wall thickness ranges from 3mm to 60mm.The lenght is normally by 3000mm(can also supply customized length accoding to client's opnion).The welded seam has undergone P+T treatment,resulting in minimal welding deforation and have a clean and smooth surface.The monthly production capacity for titanium tubes reaches 100 metric tons.

Gr12 titanium welded tube is a highly corrosion resistance and versatile engineered product,it is renowned for its exceptional performance in reducing acid and crevice corrosion environments,effectively bridging the gap between pure titanium and more expensive alloy like grade 7 or zirconium.For engineers seeking a cost-effecitive,fabricable and reliable solution for aggressive chemical and marine services,it is an ourstanding choice.

Physical Properties

Mechanical Properties

1,Versatility:performs well in both oxidizing and reducing acid environments,unlike pure titanium which is mainly suitable for oxidizing conditions.

2,Cost-Effectiveness Corrosion Resistance:provides corrosion resistance similar to the palladium-containing grade 7 but at a lower cost, making it an excellent economic alternative for many applications.

3,Excellent Fabricability:easier to form and weld than many high alloy metals,simplifying manufacturing and reducing costs.

4,Low Weigh:maintains the low density of titanium,offering significant weight saving over stainless steels,copper-nickels or nickel alloys.

Chemical processing: Reactors, heat exchangers, piping for HCl, sulfuric acid, chlorides.

Marine & offshore: Seawater cooling, desalination, ballast systems.

Oil & gas: Downhole tubing, produced water handling, CO₂/H₂S environments.

Power generation: Flue gas desulfurization (FGD), condenser tubes.

frequency-asked question

 

01/

How is it manufactured?

Strip preparation: Slit Gr12 titanium coil to width, clean surface.

Forming: Roll strip into a round tube.

Welding: TIG/GTAW or PAW welding (100% argon shield, purity ≥99.99%).

Heat treatment: Stress relief (540–650°C) or full annealing (730–820°C).

Finishing: Straightening, cutting, polishing, NDT (RT/UT/PT).

02/

What are the advantages vs. Gr2/Gr7?

vs. Gr2: Better crevice corrosion (hot chlorides, seawater), higher strength, easier welding.

vs. Gr7: Similar corrosion resistance (≤10% HCl <60°C), 30–50% lower cost, better weldability (no post-weld annealing needed).

vs. Nickel alloys: 40–60% lighter, lower cost, excellent corrosion resistance.

03/

How does it compare to seamless Gr12 tube?

Welded: Lower cost, longer lengths, consistent OD, suitable for large diameters; seam integrity critical.

Seamless: Higher pressure rating, no weld seam, better for high-pressure/critical applications; higher cost, limited length.

04/

What quality tests are performed?

NDT: 100% X-ray (RT) or ultrasonic (UT) on weld seam; pressure test.

Mechanical: Tensile, bend, hardness tests.

Corrosion: Salt spray, crevice corrosion testing.

Dimensional: OD, wall thickness, length, straightness checks.
