On-site flange machining

Flange Facing Services in Saudi Arabia

Flange facing services in Saudi Arabia that repair damaged gasket faces where the flange sits. We machine raised-face and ring-type joint flanges on site, restoring the surface finish and flatness the gasket needs, without cutting out or shipping pipework to a workshop.

Flange facing

A good joint starts with a good flange face

Even a correctly torqued joint will leak if the gasket sits on a scratched, corroded or warped face. Radial scores, pitting, weld spatter and old gasket damage all create leak paths that no amount of bolt load can close.

Our portable flange facing machines mount directly on the flange, either inside the bore or around the outside diameter, and machine the face back to a true, flat surface with the correct finish. The flange stays in place, so there is no cutting, re-welding or post-weld treatment, and the repair is usually done within one shift.

Because we also provide bolt torquing and tensioning, our flange facing services in Saudi Arabia cover the whole repair: we machine the face, fit the new gasket and tighten the joint as one job, with records for each step.

Flange facing goes hand in hand with bolt torquing: once the face is machined and the new gasket fitted, our crew tightens the joint, and the system can then be proven by hydrotesting.

What we offer

Flange facing services in Saudi Arabia

Machining, checking and reassembly from one crew, so the joint goes back into service with confidence.

Raised-face refacing

Spiral serrated, concentric serrated or smooth finishes machined to suit the gasket type specified for the joint.

RTJ groove machining

Ring grooves cleaned up or re-cut to the correct profile and finish so ring gaskets seat and seal properly.

Flatness and finish checks

Faces are measured before and after machining, and surface finish is checked against the specified range.

Heat exchanger and vessel flanges

Channel covers, girth flanges, nozzles and manways machined in place during shutdowns and turnarounds.

Weld preparation and removal

The same machines can face off welds, remove overlays and prepare flange faces and weld ends for repairs.

Machining plus bolt-up

We refit the gasket and tighten the joint with calibrated torque or tensioning tools, completing the repair in one visit.

How we work

How we deliver flange facing services in Saudi Arabia

  1. Inspect and measure

    We record the damage, check face flatness and confirm the required finish and dimensions with your engineers.

  2. Mount the machine

    An ID- or OD-mounted facing machine is fixed to the flange and centred on the bore.

  3. Machine the face

    The face is machined in light passes until all damage is removed, keeping material removal to a minimum.

  4. Verify the result

    Finish, flatness and remaining thickness are checked and recorded before the machine is removed.

  5. Protect and reassemble

    The face is cleaned and protected, then the joint is reassembled and tightened if included in the scope.

Standards and quality

Machined to the specification

Our flange facing services in Saudi Arabia follow the same safety and quality controls on every job.

  • Raised-face finishes to ASME B16.5, typically 125 to 250 µin Ra (3.2 to 6.3 µm)
  • Flatness checked against ASME PCC-1 guidance for gasket seating surfaces
  • RTJ grooves machined to the dimensions for the specified ring gasket
  • Minimum material removal to preserve flange thickness
  • Machining records for each flange, ready for your QA files
  • Work to client specifications, including Saudi Aramco and SABIC requirements

FAQ

Flange facing services in Saudi Arabia: FAQ

What is flange facing?

Flange facing is the machining of a flange's gasket surface to remove damage and restore the correct flatness and surface finish. On-site flange facing does this with a portable machine mounted on the flange, so it does not need to be removed.

Can you machine flanges without removing the pipe?

Yes. Our machines mount inside the bore or around the outside of the flange and work in place, which avoids cutting, re-welding and heat treatment.

Which surface finish will you machine?

We machine the finish specified for the gasket: commonly a spiral serrated finish for raised-face flanges with spiral wound or soft gaskets, or a smooth finish where the gasket manufacturer requires it.

Do you also tighten the joint after facing?

Yes. Our flange facing services in Saudi Arabia include fitting the new gasket and tightening the joint with hydraulic torque wrenches or tensioners, so machining and bolt-up are completed by one crew.
