Titanium Grade 12 (UNS R53400) Seamless and Welded Pipe to ASTM B861 and B862
Dinesh Tube India supplies and exports titanium Grade 12 pipes from Mumbai for desalination, salt, chlor-alkali and chemical piping in India and abroad. We supply seamless pipe to ASTM B861 / ASME SB861 and welded pipe to ASTM B862 / ASME SB862 in Grade 12 (UNS R53400, Werkstoff 3.7105), by NPS and schedule, with EN 10204 3.1 mill test certificates.
Grade 12 is a titanium alloy with 0.3% molybdenum and 0.8% nickel. Compared with Grade 2 it resists crevice corrosion in hot chloride brines far better and is about 40% stronger, at lower cost than palladium-bearing Grade 7. For all grades and the full size table, see our titanium pipes page.


Titanium Grade 12 Pipe Schedule and Weight Table
Weight (kg/m) = (OD − wall) × wall × 0.01417, using titanium density 4.51 g/cm³. Wall thicknesses per ASME B36.19.

Grade 12 Piping Package
For hot-brine service, every wetted part of the line should be Grade 12, so that fittings and flange faces do not become the weak points. We can supply the complete package:
Grade 12 Fittings
WPT12 elbows, tees, reducers, caps and stub ends to ASTM B363.
Grade 12 Flanges
F-12 weld neck, slip-on, blind and lap-joint flanges to ASTM B381.
Grade 12 Plate
B265 Grade 12 plate for vessel shells, linings and tubesheets.

Titanium Grade 12 Pipe Applications
Titanium Grade 12 Pipes: FAQs
Which standards cover titanium Grade 12 pipe?
Seamless Grade 12 pipe is made to ASTM B861 (ASME SB861) and welded Grade 12 pipe to ASTM B862 (ASME SB862). Both cover pipe sized by NPS and schedule.
What is titanium Grade 12?
Titanium Grade 12 (UNS R53400, Werkstoff 3.7105) is a titanium alloy with 0.2–0.4% molybdenum and 0.6–0.9% nickel. It is stronger than Grade 2 and resists crevice corrosion in hot chloride brines.
Is Grade 12 pipe available seamless and welded?
Yes. Seamless pipe to B861 is common in small and medium sizes; welded pipe to B862 is usually more economical in larger sizes and thin walls.
How much does titanium Grade 12 pipe weigh?
Weight in kg/m = (OD − wall) × wall × 0.01417, with OD and wall in mm. For example, 2" Sch 10S (60.33 × 2.77 mm) weighs about 2.26 kg/m.
Should I use Grade 12 or Grade 7 pipe?
Grade 12 is stronger and lower cost and suits most hot-brine and desalination service. Grade 7 (with palladium) is better in strongly reducing acids.
What is the price of titanium Grade 12 pipe?
The price depends on NPS, schedule, seamless or welded, length, quantity and certification. Send your requirement to kamlesh@dineshtube-india.com or call +91 83559 10913 for a current quote.
Which certificates come with Grade 12 pipes?
Every supply comes with an EN 10204 3.1 mill test certificate showing heat number, chemical analysis and mechanical properties to ASTM B861 or B862. EN 10204 3.2 certificates and third-party inspection can be arranged on request.
