HYDRAULIC FLUSHING

Techenomics has extensive experience with the Hydraulic Flushing of pipework associated with marine and offshore installations. The process will flush contaminants from the piping system by high-turbulence oil velocity circulation, where the contaminant will be effectively trapped in the filter. The Clean Oil after filtration will be pumped back into the piping system to flush out the remaining contaminant, and the process will be repeated continuously until the system is at the required NAS code.
The Cleanliness of the Hydraulic Oil Flushing Medium will be controlled by an inline particle counter capable of indentifying real time cleanliness levels of the Piping system throughout the flushing process. The Cleanliness level will be compaired to NAS and/or ISO cleanliness Level ( JS ).

The predominant cause of “initial failure” and operational downtime of the hydraulic system is usually the result of particles and other contaminants in the hydraulic system. It is vital that these systems are flushed prior to commissioning. It is common for large particles such as grime, welding slag, worn metal, gasket pieces, sand, sealant etc, to be present prior to commissioning. All these contaminants can cause sudden failure or damage to pumps, motors valves, bearings, actuators, and pistons. Contamination in the piping system and the oil medium can clog the gaps between the housing and spool valves, resulting in leaking valves and malfunction of the hydraulic system. To avoid these situations, Hydraulic Flushing is required before any commissioning of equipment.
