On-site flange face repair during a refinery shutdown
Portable TFS-I610 and TFS-I1000 flange facers restore raised faces and RTJ grooves in place, so leaking joints are fixed without replacing flanges.

The challenge
Shutdown windows are short. Flanges with pitted, scored or corroded faces cannot be sealed again with a new gasket, and cutting them out for replacement adds welding, NDT and stress relief to the critical path.
The solution
Crews mount ID-clamping TFS-I610 and TFS-I1000 machines directly in the flange bore, re-cut the raised face with a spiral serrated finish and, where needed, recut RTJ grooves. Blind flanges and valve faces go to the OD-mounted TFP-O300, and small-bore flanges in confined spaces are dressed with the manual TFF-M355S.
Workflow
- Inspect and record face damage depth
- Mount and centre the machine in the bore; check run-out
- Skim to clean metal with the minimum stock removal
- Cut the specified serrated finish or RTJ groove
- Verify flatness and finish, then release for gasket fit
Outcome
Flanges go back into service with a new gasket instead of being replaced, keeping repair work off the shutdown critical path.
