Valves & Hydraulic Flushing
Treatment for valves using oxygen or peroxide to ASTM standards. Flush hydraulics.
It is vital to clean the piping system of hydraulic installation prior to commissioning. It is essential to maintain the cleanliness during the life span of the installation. The resulting benefits enable to:
• Reduce: downtime and repair costs.
•
Increase: Production capacity and equipment life time.
Among the piping circuit pollution causes, presence of particles (manufacturing residue like welding slag) or results of natural or early equipment wear or aging (abrasion, erosion, fatigue surface wear, etc.) can lead to failure or damage to production equipment resulting in operation downtime.
With a clean, preventive or corrective approach, it is essential to guaranty:
• Filtration (even with a new oil) – to prevent early breakdown.
•
Flushing before commissioning or after maintenance.
•
Filtration during the system filling.
To answer to the need, the Hydraulic Flushing technology by Groupe N.E.T. Tech Plus enables to clean the pipe work or the circuit of the installations. The Hydraulic Flushing is working at high velocity (fluid velocity > 10 m/s) and with high turbulence flow (Reynolds > 4000), enabling to reach the requested level of cleanliness specified in the standards (NAS 1638 et ISO 4406) with a documented and traceable process and results. The capacity reaches a high flow filtration (up to 150 GPM).
Why maintaining the turbulent flow?
This is precisely the key and the justification of the hydraulic flushing! By reaching and maintaining a turbulent flow, the fluid viscosity gives the required drag to cleaning the inner sides. The flushing fluid, usually oil, is contained in a large capacity tank and can be potentially heated to better control the viscosity and monitor for an optimum flushing. The released particles, such as grime, worn metal, welding slag, sealant, sand, etc., are captured by the filtration system. When the human eye can only see particles bigger than 40 μm (a human hair measures about 75 μm), the filters are generally capturing the dirt than can be 10 times smaller. To prevent a breakdown due to presence of particles and other contaminants in the hydraulic system, before any commissioning of equipment: valves, pumps, motors, actuators, etc., the hot oil flushing is required. Even the new installations are exposed to risks at start up that could lead to "initial failure" or malfunction resulting in an operational downtime. By accomplishing the flushing of the hydraulic circuit, the cleaning of particles is required for a smooth and trouble free operation!
