Titanium Long Weld Neck vs Standard Weld Neck Flange
2026-08-11
A standard weld neck flange uses a defined tapered hub for joining pipe. A long weld neck flange extends the neck substantially and is often drawing-controlled for vessel, column or nozzle connections.
Key Differences
| Item | Standard weld neck | Long weld neck |
|---|---|---|
| Neck | Standard hub geometry | Extended, project-defined length/profile |
| Connection | Butt weld to pipe | May act as extended nozzle or reinforced connection |
| Order data | Size, class, facing, bore and schedule | Add overall length, wall, transition radii and detailed drawing |
Do Not Extend a Standard Flange Informally
Changing neck length and wall geometry affects weight, machining, forming, inspection and potentially design analysis. Use an approved drawing and governing pressure-equipment or piping design basis.
