Hydrotest Services in Ras Tanura
New and repaired lines at the Ras Tanura terminal and refinery must be proven before product goes back in. We test, record and dewater them.
Testing terminal lines at Ras Tanura
Large-bore terminal lines and refinery modifications at Ras Tanura need hydrotesting after repairs and tie-ins. Hydrotest services in Ras Tanura include filling, pressurising, holding and recording, then dewatering and drying so lines can return to crude or product service.
Pressure is brought up in stages to the value the governing code requires, held while joints and welds are inspected, and logged on calibrated gauges and a recorder.
Most hydrotesting jobs in Ras Tanura are part of a wider joint repair, so the same crew can also handle bolt torquing in Ras Tanura and the other services below. For methods, equipment and standards, see our main hydrotest services in KSA page.
