RTJ groove machining
Ring grooves cleaned up or re-cut to the correct profile and finish so ring gaskets seat and seal properly.
Flange facing services in Abqaiq for crude oil processing facilities, gas-oil separation plants and other sites across Abqaiq. We machine raised-face and RTJ flanges in place, restoring the gasket surface without removing pipework.
Flange Facing in Abqaiq
Abqaiq is home to one of the world's largest crude oil processing and stabilization facilities, surrounded by gas-oil separation plants, pipelines and pumping stations. It is an inland desert location, so crews deal with extreme summer heat and blowing sand, and work is planned around facilities that are critical to national crude supply and cannot be taken out of service lightly.
Sand and heat in Abqaiq damage exposed flange faces whenever joints are opened, and sour or wet crude service can pit faces over time. We machine damaged faces on site at processing plants, GOSPs and pumping stations, protecting the machined surface from sand until the joint is closed.
Our flange facing services in Abqaiq use the same calibrated equipment, procedures and reporting we use on sites across the Kingdom.
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
Ring grooves cleaned up or re-cut to the correct profile and finish so ring gaskets seat and seal properly.
Channel covers, girth flanges, nozzles and manways machined in place during shutdowns and turnarounds.
We refit the gasket and tighten the joint with calibrated torque or tensioning tools, completing the repair in one visit.
Our bolting crews mobilize with calibrated equipment across Saudi Arabia, 24 hours a day.
FAQ
Faces are covered and sealed immediately after machining and stay protected until the gasket is fitted, so blowing sand does not scratch the new finish.
We schedule heavy work for cooler hours where the site allows, rotate crews, provide shade and water, and protect machines and instruments from sand and heat so work continues safely through the summer.
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.
Other locations
