Product Detail
Product Introduction
Titanium Slip-On Flange is a forged and machined titanium piping component identified by its low hub and bore that fits over the pipe. Material grade, dimensional standard, nominal size, pressure class, facing, mating component and service conditions must be reviewed together.
When should a titanium slip-on flange be considered?
Selection answer: A slip-on flange fits over the pipe and is normally attached by internal and external fillet welds. It can simplify fit-up when the piping design permits this connection style.
Selection boundary: Its hub and weld geometry differ from a weld neck flange, so fatigue, bending, crevice exposure and inspection access must be reviewed. A lower purchase price alone is not a sufficient selection basis.
RFQ data to confirm: Provide grade, NPS, class, facing, flange bore, connected-pipe OD and schedule, weld procedure, design pressure and temperature, service medium, quantity, inspection and certificates.
Product Specifications
| Product | Titanium Slip-On Flange | Grade | Titanium Grade 2, Grade 5, Grade 7, Grade 12 or specified alloy |
|---|---|---|---|
| Standard | ASTM B381 / ASME SB381 may govern titanium-alloy forgings; ASME B16.5 or an approved EN, DIN, JIS or project standard may govern dimensions, pressure class and facing. The applicable piping code and project specification control selection and rating. | Size & Form | NPS/DN and Class/PN according to the specified dimensional standard or customer drawing |
| Tolerance | Applicable material/dimensional standard and order-defined bore, hub, facing, bolt circle, hole and connection tolerances | Supply Condition | Forged and machined with protected sealing faces, individual identification and reinforced export-case packing |
| Inspection | MTC and heat traceability, PMI when specified, nominal size and pressure class, OD and thickness, bore and connection geometry, bolt circle and holes, facing and surface finish, visual inspection and supplementary NDE when required. | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Connection function | A slip-on flange slides over the pipe and is normally attached with internal and external fillet welds. The bore must suit the pipe OD and the pipe-end setback must be defined. |
|---|---|
| Critical dimensions | State NPS, class, facing, dimensional standard, flange bore, pipe OD and wall, face finish, bolt drilling, thickness and grade. |
| Fabrication interface | Define pipe projection or setback, alignment, cleaning, filler, shielding and fillet-weld procedure. Slip-on and socket-weld flanges are not interchangeable connection details. |
| Inspection focus | Inspect bore, facing, thickness, bolt circle and holes, surface, marking and traceability; check fit-up and both fillet welds to the project inspection plan. |

Services We Can Provide
Product Packaging
Machined faces, bores and bevels are protected with covers or wrapping. Flanges are separated by grade, size and heat, then secured in reinforced export cases with traceability labels. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios

Material grade, dimensions, condition and inspection must be matched to the application requirements.
Chemical processing and corrosion-resistant piping
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Marine, desalination and industrial equipment connections
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Does ASTM B381 define flange pressure class and dimensions?
No. ASTM B381 primarily covers titanium forgings. State the separate dimensional standard, size, class or PN, facing and project requirements.
Which titanium grade should be selected?
Grade selection depends on service chemistry, temperature, strength, mating materials, fabrication and the governing project specification.
What information is required for quotation?
Provide grade, material and dimensional standards, size, class/PN, facing, bore or connection details, quantity, NDE and certificates.
