A weld-neck flange is a separate component fitted and welded to the pipe. With flanging, the pipe end is formed into a lip or stub end backed by an appropriate loose flange. The complete connection must suit the project design.
What should you measure?
- Flange cost and stock availability.
- Preparation, positioning and welding time.
- Finishing, inspection and any rework.
- Changeover time between pipe sizes.
- Production volume and the range of variants.
Where can flanging help?
It is worth assessing for pipe packages where flange handling and welding account for a significant share of the work. T-DRILL states that its process can save up to 40% of the time compared with traditional weld-neck connections. This is a manufacturer’s reference figure; the achievable result needs verification for the actual geometry and production route.
Check the application limits
The material, wall thickness, flange dimensions, sealing arrangement, operating conditions and applicable design requirements can call for a different solution. Confirm suitability against the project and, where required, a trial.
