Titanium Pipe Flange Buying Essentials
Flange Class Is Not a Standalone Working-Pressure Rating
Titanium flange sourcing depends on flange type, material grade, raw-material route, NPS or DN, Class or PN, facing, bore or mating pipe schedule, dimensional standard and inspection requirements.
Define these parameters before quotation to match the flange with the piping specification and connection design.
Flange Type & Manufacturing Route
Start with the required flange configuration and confirm whether the component is manufactured from a forged blank, plate-cut blank or another approved raw-material route according to the project specification.

Finished Pipe Flanges vs. Forged Rings & Custom Rings
This page covers finished titanium pipe flanges manufactured to standard or drawing-based connection requirements. Raw forged rings, rolled rings and forging blanks belong to the titanium forgings product family, while non-flange machined rings should be specified separately as drawing-based machined components.
How to Choose the Right Titanium Pipe Flange
Select titanium pipe flanges by flange type, material grade, raw-material route, nominal size, Class or PN, facing, bore, mating pipe dimensions, applicable standard and inspection requirements to match the complete piping-joint specification.
Choose the Flange Type
Start with the required connection design and select the flange configuration according to the mating pipe, equipment connection and piping arrangement.
Confirm Grade & Raw-Material Route
Specify the titanium grade, UNS or F-Grade together with the required raw-material route so the flange material and manufacturing process can be reviewed against the project specification.
Define NPS, DN & Class / PN
Specify the nominal flange size and applicable Class or PN designation according to the dimensional standard and project piping specification.
Define Face, Bore & Mating Pipe
Confirm the flange-facing configuration and bore requirements together with the mating pipe OD, Schedule or actual wall thickness and gasket arrangement where applicable.
Confirm Standard or Drawing
Define the applicable dimensional standard and edition, or provide an approved drawing for custom flange dimensions, bolt pattern, hub geometry, facing and tolerances.
Define Inspection & Documentation
Confirm material traceability, dimensional inspection, surface and facing requirements, marking, NDT and project documentation according to the flange type, manufacturing route and purchase specification.
Flange Selection Must Match the Complete Joint Design
Flange type, material, Class or PN, face, bore, mating pipe, gasket, bolting and design temperature should be reviewed together under the applicable piping code and project specification. Product selection on this page does not replace project engineering approval.
*Availability of flange type, raw-material route, facing, dimensional standard, NDT and documentation depends on grade, size and project requirements.
Titanium Grades for Pipe Flanges
Select the titanium grade according to the project material specification, service environment, mechanical requirements and flange manufacturing route. Final availability is confirmed by flange type, raw-material form, NPS or DN, Class or PN, facing and project requirements.
Material Grade and Flange Standard Are Different Decisions: The titanium grade defines the material chemistry and mechanical requirements, while flange dimensional standards define geometry, dimensions, facing and Class or PN systems. ASTM B381 may apply to forged titanium material, while ASME B16.5, ASME B16.47 or other project standards may define the flange dimensional pattern where applicable.
Availability Note: Not every titanium grade is available in every flange type, size, Class or PN, facing or raw-material route. Final Grade × Type × Size × Class × Face availability is confirmed during quotation review.
Grade 2 Titanium
UNS R50400 · Commercially Pure Titanium
Grade 2 provides a practical balance of strength, ductility, fabrication performance and corrosion resistance for a broad range of industrial titanium flange and piping applications.
Grade 5 Titanium
UNS R56400 · Ti-6Al-4V
Grade 5 offers higher strength than commercially pure titanium and can be reviewed for flange applications where alloy strength, geometry, manufacturing route and project-specific design requirements justify its use.
Grade 7 Titanium
UNS R52400 · Ti-0.2Pd
Grade 7 is a palladium-alloyed commercially pure titanium grade that can be reviewed for corrosion-sensitive flange and piping applications where the project material specification requires enhanced corrosion performance.
Grade 12 Titanium
UNS R53400 · Ti-0.3Mo-0.8Ni
Grade 12 combines titanium with molybdenum and nickel and can be reviewed for industrial flange applications requiring a project-specific balance of strength, fabrication performance and corrosion resistance.
Engineering Note: Allowable pressure and temperature depend on the flange geometry, material, dimensional standard, design temperature, gasket, bolting and applicable piping code. Grade selection and flange-joint design should therefore be reviewed as separate but related engineering decisions.

Material Specifications vs. Flange Dimensional Standards
Titanium flange procurement usually involves more than one technical reference. Material specifications define the titanium product and material requirements, while dimensional standards define flange geometry, class systems and interface dimensions. Inspection documents should be specified separately.
The applicable standard, edition and project requirements should be confirmed before quotation and production.
ASTM B381 / ASME SB-381
Covers titanium and titanium-alloy forgings. When specified for a flange, the applicable grade, material condition, heat requirements and inspection documentation should be confirmed against the purchase specification.
ASTM B265
Applies to titanium sheet, strip and plate. It may be relevant to plate-based rings, blind components or custom machined parts where the approved manufacturing route uses plate rather than a forging.
ASME B16.5
Defines pipe flange dimensional requirements, Class designations, tolerances, marking and related requirements within its applicable scope. Titanium material suitability and pressure-temperature design must still be confirmed for the project.
ASME B16.47
Used for large-diameter flange dimensional requirements where the project specifically calls for the applicable Series and size range. Material suitability and project design requirements must be reviewed separately.
EN / DIN / JIS Dimensional Patterns
European, German or Japanese flange dimensional patterns can be reviewed when specified by the project. Material grade, PN/Class, facing and dimensional compatibility should be verified before production.
EN 10204 3.1
Defines an inspection certificate type for supplied material or products. It is not a flange material specification or dimensional standard. Availability should be confirmed against the order and documentation requirements.
Engineering Note
Matching a flange to a dimensional standard does not automatically establish the allowable working pressure for every titanium grade, temperature or service condition. Final joint and pressure design should be approved under the applicable piping code and project engineering requirements.
