Hydro testing services

Aker Qserv can offer yydro testing / hydrostatic tests that are conducted under the constraints of either the industry's or the customer's specifications.

After construction, all hydrocarbon process system pipework is required to be subjected to a strength test, using water or a suitable fluid as the test medium. This is referred to as hydraulic testing or hydro testing. In order to perform an effective hydro test, air needs to be removed from the system, otherwise it will negatively influence the results. The Aker Qserv hydrotest packs are designed so that the system high-point has a vent to atmosphere, so that all the air within the system can be removed whilst being filled with water. During filling of the system with water, chemicals can be added to prevent flash corrosion when the system is tested and drained. Once the system is filled, it will be pressurised in stages to its final test pressure, using a high-pressure fluid pump. Because water is virtually incompressible, the amount of water which must be injected to raise the pressure is very small relative to the volume of the system being tested. Sometimes this means that a hand-operated pump will be all that is needed, though more usually, a combination of hand and air-driven pumps are used.

Aker Qserv owns and operates many complete sets of process and pipeline hydro testing equipment with very experienced personnel that have been fully-trained in its operation and project management.
