Polished titanium elbow fittings with beveled ends

Titanium Buttweld Fittings

Titanium Buttweld Fittings supplied by titanium grade, outside diameter or NPS, wall thickness, end preparation, dimensional standard and inspection requirements for corrosion-resistant piping systems.

Material: Titanium Grade 2, Grade 7 or Grade 12 as specified
Product Standard: ASTM B363 / ASME SB363 where applicable
Dimensions: ASME B16.9, B16.11 or approved drawing
Documents: MTC, dimensions and heat/lot traceability

Product Detail

Product Introduction

Titanium Buttweld Fittings connects or changes the direction, branch, size or termination of titanium piping while maintaining material compatibility and corrosion resistance. Final selection requires the titanium grade, pipe dimensions, wall thickness, geometry, end preparation, pressure design basis and inspection plan.

How should a titanium buttweld fitting be specified?

Selection answer: Start with the fitting geometry, connected pipe dimensions and governing piping design, then select a titanium grade using corrosion, strength, fabrication and welding requirements. The generic page covers multiple grades rather than replacing a grade-specific specification.

Selection boundary: A matching outside diameter is not enough: wall or schedule, center-to-end dimensions, bevel, manufacturing route, heat treatment, weld quality and code acceptance must all be defined.

RFQ data to confirm: State elbow, tee, reducer, cap, stub end or drawing; grade; NPS or OD; wall or schedule; dimensional standard; bevel; seamless or welded route; quantity; NDT and documents.

Typical ranges are quotation guidance, not a stock guarantee. Final availability and tolerances are confirmed against the complete RFQ and design code.

Selection and Configuration

Material compatibility: Match the fitting grade, source product and welding procedure to the connected titanium pipe and service environment.
Dimensional definition: State NPS or outside diameter, wall thickness or schedule, center-to-end dimensions and end preparation.
Fabrication route: Specify seamless, welded, formed, forged, machined or drawing-controlled construction as applicable.

Pressure-design note: Dimensional conformity does not by itself establish pressure rating. The piping designer must verify material allowable stress, wall thickness, weld joint, corrosion allowance, temperature and governing construction code.
