Titanium Butt-Weld Fittings to ASTM B363: Elbows, Tees, Reducers, Caps and Stub Ends
Dinesh Tube India supplies and exports titanium pipe fittings from Mumbai to chlor-alkali, desalination, refinery, offshore and chemical projects in India and abroad. Our titanium fittings are made to ASTM B363 / ASME SB363 with dimensions to ASME B16.9, in commercially pure Grade 2 (WPT2) and the alloys Grade 7 (WPT7), Grade 12 (WPT12), Grade 9 (WPT9) and Grade 5 (WPT5). Every supply comes with an EN 10204 3.1 mill test certificate.
A fitting should be the same grade as the titanium pipe it joins. Elbows, tees and reducers are where flow turns, deposits collect and crevice attack starts, so a lower-grade fitting becomes the weak point of the line. Choose a grade below to see full data for each.
Titanium Pipe Fitting Grades
Grade 2 Fittings (WPT2)
Commercially pure titanium (UNS R50400). The standard grade for seawater, wet chlorine and chloride service.
Grade 7 Fittings (WPT7)
Ti-0.15Pd (UNS R52400). Best resistance to dilute reducing acids and severe crevice conditions.
Grade 12 Fittings (WPT12)
Ti-0.3Mo-0.8Ni (UNS R53400). Stronger than Grade 2 and resistant to hot brines, at lower cost than Grade 7.
Grade 5 & Grade 9 Fittings
High-strength alloys: Grade 9 (Ti-3Al-2.5V, WPT9) and Grade 5 (Ti-6Al-4V, WPT5), mostly made to order.
Types of Titanium Fittings
Titanium Elbow
90° and 45°, long radius (1.5D) and short radius (1D), plus 180° returns.
Titanium Tee
Equal and reducing tees for branch connections.
Titanium Reducer
Concentric for vertical lines, eccentric for pump suctions and horizontal lines.
Titanium Cross & Cap
Equal and reducing crosses (on request) and butt-weld end caps.
Titanium Pipe Bend
3D, 5D or custom-radius bends to drawing (on request).
WPT Marking Explained
ASTM B363 grade symbols start with WPT (wrought pipe fitting, titanium) followed by the titanium grade number. A "W" suffix means the fitting is made from welded material or contains welds:
Titanium Pipe Fitting Mechanical Properties (Minimum)
Titanium Pipe Fitting Chemical Composition (%, max unless range)
Titanium balance. Check the current ASTM B363 edition (B363-23) and the mill certificate for governing values.
Which Titanium Fitting Grade to Choose
Titanium is not suitable for hydrofluoric acid, fluoride-bearing solutions or dry chlorine gas. If in doubt, send the process fluid, temperature and concentration and we will suggest a grade.

Installation Notes
Titanium Pipe Fitting Applications
Titanium Pipe Fittings: FAQs
Which standard covers titanium pipe fittings?
ASTM B363 (ASME SB363) covers seamless and welded titanium and titanium alloy butt-weld fittings. Dimensions follow ASME B16.9, with B16.28 for short-radius elbows and MSS SP-43 for short stub ends.
Which grades of titanium fittings do you supply?
We supply Grade 2 (WPT2), Grade 7 (WPT7) and Grade 12 (WPT12) fittings, and the high-strength Grade 9 (WPT9) and Grade 5 (WPT5) mostly to order. Grade 1 and Grade 3 can be arranged on request.
What types of titanium fittings are available?
Butt-weld 90° and 45° elbows, 180° returns, equal and reducing tees, concentric and eccentric reducers, caps and stub ends, with crosses and custom pipe bends on request.
What is the difference between WPT2 and WPT2W?
Both are Grade 2 titanium fittings to ASTM B363. WPT2 is seamless; the "W" in WPT2W means the fitting is made from welded material or contains welds.
What are titanium butt-weld fittings used for?
They join titanium pipe in seawater, desalination, chlor-alkali, refinery, offshore and chemical plants, where titanium resists chlorides and wet chlorine far better than stainless steel or copper-nickel.
What is the price of titanium pipe fittings?
The price depends on grade, fitting type, NPS, schedule, seamless or welded, quantity and certification. Grade 7 costs more than Grade 2 because of its palladium. Send your fitting list to kamlesh@dineshtube-india.com or call +91 83559 10913 for a current quote.
Which certificates come with titanium fittings?
Every supply comes with an EN 10204 3.1 mill test certificate showing heat number, chemical analysis and mechanical properties to ASTM B363. EN 10204 3.2 certificates and third-party inspection can be arranged on request.
