Titanium 45° & 90° Elbows
Specify: Angle · LR/SR · NPS/DN · Wall · Ends
Direction-change fittings reviewed against the ordered geometry, construction, dimensions, wall and end preparation.

Elbows · Tees · Reducers · Caps · Stub Ends
Specify fitting type, grade, NPS or DN, schedule or nominal wall, construction, dimensional standard, geometry, end preparation, inspection and documents before comparing quotations.
Before comparing quotations: align the material specification, dimensional standard, mating pipe, construction, wall, end preparation, tests, documents and project exceptions. A fitting name and Grade alone are not a complete order.
Titanium Pipe Fitting Types
Elbows, tees, reducers, caps and stub ends cannot be ordered from the family name alone. Each part needs its own size combination, geometry, wall, construction, ends and inspection basis.
Specify: Angle · LR/SR · NPS/DN · Wall · Ends
Direction-change fittings reviewed against the ordered geometry, construction, dimensions, wall and end preparation.
Specify: Radius · Center-to-center · Wall · Construction
Return fittings for compact routing, supplied only after radius, dimensional basis and fabrication route are confirmed.
Specify: Run size · Branch size · Wall · Construction
Equal-branch fittings reviewed for material, outlet geometry, dimensions, wall and required inspection.
Specify: Run × branch sizes · Wall · Geometry
Reducing branches defined by complete run and outlet sizes rather than a single nominal designation.
Specify: Large end × small end · Length · Wall · Ends
Axis-aligned transitions supplied against the ordered size combination, dimensional standard and end-preparation basis.
Specify: Size combination · Offset orientation · Length · Wall
Offset transitions reviewed with orientation, flat-side position, dimensions, construction and service arrangement defined.
Specify: NPS/DN · Wall · Shape · End preparation
End closures supplied against the specified material, dimensions, wall, geometry and fabrication requirements.
Specify: Type · Lap · Length · Wall · Backing flange
Stub ends reviewed together with mating pipe, backing flange, gasket arrangement and project dimensional basis.
Type, size, wall, construction, end preparation and availability are confirmed per quotation for each fitting.
Supply Scope & Qualification
Do not combine all types, grades, sizes and walls into one broad capability claim. The exact combination must be reviewed against material, tooling, construction, heat treatment, inspection and documentation.
| Order item | Required definition | Acceptance decision |
|---|---|---|
| Type and geometry | Angle/radius, run and branch, size transition, cap or stub-end type | Drawing or dimensional standard matches the MTO |
| Material | Grade/UNS, material standard and revision, condition | MTC, source material and marking agree |
| Size and wall | NPS/DN, schedule or nominal wall, mating pipe | Dimensions and transition are compatible |
| Construction and ends | Seamless/welded/fabricated route and bevel/end preparation | Ordered classification and fit-up evidence are available |
| Inspection and documents | Dimensions, wall, visual/NDE, marking, traceability and reports | Method, sampling and acceptance are defined |
Pressure capability is not selected from Schedule alone.
Material, design temperature, corrosion allowance, construction, weld quality, applicable piping code and system design remain under the responsible engineering authority.
Standards Map
Material, manufacture, testing and marking for titanium welding fittings within its scope; invoke the PO-specified edition and classification.
Overall dimensions, tolerances, ratings, testing and marking for factory-made wrought buttwelding fittings within its scope; not proof of titanium Grade.
Butt-welding end preparation and related dimensions where specified by the project or governing code.
Apply MSS SP-43 or forged fitting requirements such as ASME B16.11 only where the product form and project specification require them.
Process Review
Link the billet, bar, plate, pipe or tube input to the ordered Grade, specification and heat/lot.
Identify seamless, welded or fabricated construction and the forming, welding and heat-treatment responsibility.
Check dimensions, wall, ovality, angle/radius, branch or transition, bevel and surface against agreed methods.
Align marking, MTC, inspection/NDE records, deviation approvals, packing list and shipment identity.

A generic certificate or factory photograph cannot replace order-specific material identity, dimensional results, weld/NDE records where applicable, marking and traceability.
Application Review
Industry labels do not prove suitability. The project engineer remains responsible for material selection, pressure-temperature design, corrosion review, fabrication, inspection and code compliance.

Define media, concentration, contaminants, temperature, pressure, piping code, corrosion allowance and fabrication requirements.

Define seawater conditions, velocity, temperature, crevice risks, mating materials and system design responsibility.
Review the application context →
Align fittings with mating pipe/tube, equipment nozzles, fabrication drawings, inspection and design code.
Review the application context →
Freeze line class, MTO, revision, isometrics, quantities, inspection points, documents, packing and delivery sequence.
Review the application context →System Compatibility
Match material, dimensions, wall transition, end preparation, welding basis, lap geometry, backing flange, gasket and fasteners. A compliant individual component can still create a poor joint when interfaces are not aligned.

Frequently Asked Questions
Provide fitting type, grade/UNS, material specification and revision, NPS or DN, schedule or nominal wall, construction, dimensional standard, geometry, end preparation, quantity, inspection, documents and mating-pipe information.
No. ASTM B363 is a material, manufacturing and inspection specification for titanium welding fittings within its scope. Dimensional and end-preparation requirements may come from ASME B16.9, ASME B16.25, MSS SP-43 or an approved project drawing, as applicable.
No. Schedule or nominal wall is only one input. Material, design temperature, corrosion allowance, construction, joint quality, piping code and system design must be evaluated by the responsible engineer.
They use different starting material and manufacturing routes and may have different examination and marking requirements. State the required construction and governing specification rather than assuming one is always preferable.
It can be quoted, but fit-up risk remains unless the buyer also defines stub-end type and length, lap dimensions, mating pipe, backing flange, gasket arrangement and dimensional standard.
No. They depend on type, grade, size, wall, construction, tooling, source material, inspection, quantity and documentation. Confirm them against the exact order basis.
