Pre commissioning cleaning and flushing of hydraulic and lube oil systems is employed to insure that new rotating and hydraulic equipment will start up and operate as designed with a greatly reduced potential of premature failure. Contaminants such as rust, scale, slag, sand, dirt and oils can contaminate, foul and become trapped in bearing races, rotating equipment causing significant damage. Particles as small as five microns in size can cause significant damage if allowed to remain or become trapped in the process system. With proper cleaning of the system prior to operation, bearings, control valves, instrumentation and critical operating systems are subjected to far less wear, scoring and heating by scale, slag and construction debris. The cleaning process is normally conducted in three stages: removal of oils and varnishes, velocity flushing to remove particulate and debris, introduction and filtration of the lube oil. It is not unusual for the actual system product to contain significant particulate which must also be removed to prevent damage to the operating equipment.

Applications within the Energy industry for this process include:

• Cleaning of hydraulic control systems
• Cleaning of Subsea control lines
• Compressor lube oil system cleaningw
• Marine vessel control system cleaning
• Steam & Gas Turbines lube systems,
• High efficiency heat exchangers
• On Line Oil Filtration
• Electrical Transformer Oil Filtration

Lube oil flushing services are used to extend the life cycle of lubrication systems during commissioning and following periodic maintenance and repair services. Any facility that has a low tolerance for failures can use this service as a key pillar for their preventative maintenance program.
