Flange Facing Services in Abqaiq
High-pressure joints at Abqaiq often use ring-type gaskets. A worn groove will leak whatever the bolt load, so we re-cut it on site.
Machining high-pressure flanges in Abqaiq
Crude processing and pipeline facilities at Abqaiq rely on high-pressure flanges, many with ring-type joints. Flange facing in Abqaiq covers re-cutting worn ring grooves and refacing raised faces in place, followed by controlled bolting so the joint is closed correctly.
After machining we check the finish against a comparator and take flatness readings, so the joint can be rebuilt on a face that will actually seal.
Most flange facing jobs in Abqaiq are part of a wider joint repair, so the same crew can also handle bolt torquing in Abqaiq and the other services below. For methods, equipment and standards, see our main flange facing services in KSA page.
