Pneumatic testing
Where water cannot be used, pneumatic tests with the additional precautions and exclusion zones they require.
Hydrotest services in Abqaiq for crude oil processing facilities, gas-oil separation plants and other sites across Abqaiq. We test piping, pipelines and vessels to the approved test pack, then drain, dry and reinstate the system.
Hydrotest 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.
New and modified pipelines, pumping station piping and processing plant systems in Abqaiq are hydrotested before they carry crude or gas. Water must often be brought to remote sites and disposed of properly afterwards, so we plan supply, storage and draining as part of every test.
Our hydrotest services in Abqaiq use the same calibrated equipment, procedures and reporting we use on sites across the Kingdom.
Testing ties in with our other services: test blinds and flanges are made up by bolt torquing, damaged faces found during testing are repaired by flange facing, and lines are dried afterwards by nitrogen purging.

FAQ
We plan water supply, storage, filling and disposal with the site in advance, so the test is not held up waiting for water or a route to drain it.
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.
The test pressure comes from the design code and your specification. For process piping to ASME B31.3, for example, it is normally 1.5 times the design pressure, adjusted for temperature. We work to the value in the approved test pack.
