Nitrogen leak testing
Pressurising systems with nitrogen to check flanged joints and connections before start-up, with leaks fixed by our bolting crew.
Nitrogen purging services in Ras Tanura for refinery process units, crude oil export terminals and other sites across Ras Tanura. We purge, inert, dry and leak test systems with nitrogen and confirm every vent against your target.
Nitrogen Purging in Ras Tanura
Ras Tanura is the site of one of Saudi Arabia's largest refineries and one of the world's biggest crude oil export terminals, with tank farms, loading lines, manifolds and subsea pipelines running out to the berths. The work here is shaped by the sea: marine corrosion, large-diameter lines, and jetty and terminal schedules that are planned around tanker movements.
Before crude and product lines in Ras Tanura are opened for maintenance, they have to be cleared of hydrocarbons. After work, the air has to be removed before product returns. Nitrogen purging covers both, and long terminal lines are often cleared by nitrogen-driven pigging, which pushes product out ahead of the pig and leaves an inert line behind.
Every job under our nitrogen purging services in Ras Tanura starts with a site survey and a written method statement, and ends with a record of the work for your files.
Purging is often the last step in a sequence that includes hydrotesting of new lines and flange facing of damaged joints, and our crews can deliver the whole sequence.

FAQ
Yes. Long lines are purged in stages or with nitrogen-driven pigging, with oxygen and hydrocarbon readings taken at each receiver or vent until the agreed target is reached.
Yes. We plan jobs around loading windows and terminal permits, and can split work into short tasks that fit between vessel movements when a line cannot be out of service for long.
The acceptance target is agreed before the job, for example a maximum oxygen or hydrocarbon level or a minimum dew point. We measure at every vent with calibrated instruments and record when each point meets it.
