Oil Flushing Of Hydraulic Pipelines Services

Cleanliness in Hydraulic systems has received considerable attention recently. Hydraulic systems are extremely sensitive to contamination. Fluid cleanliness is of primary importance because contaminants can cause component malfunction, prevent proper valve seating, cause wear in components, and may increase the response time of servo valves and cylinders. The inside of a Hydraulic system can only be kept and clean as the fluid added to it.

GENERAL CLEANING AND FLUSHING REQUIREMENTS:

1.Chemically clean and treat internal surfaces of hydraulic lines.
2.Perform hot oil flushing to reach target cleanliness level.
3.Inspect and verify that the cleanliness level has been achieved.
4.Follow the proper steps when disassembling the flushing loops to prevent contaminants from re – entering the cleaned system. Seal off all openings with plugs, blind flanges and Plastic sheets.

CHEMICAL CLEANING:

The object for acid carrying out cleaning of Hydraulic Pipelines is to remove mill scale, oil, paint, preservatives, rust, welding slag that would have entered during assembly of new tubes and also to remove the oxides of iron. After carrying out the process, the internal surface of the system is passivated by means of protective layer to prevent further rusting and corrosion.

PHASE – I – ALKALINE DEGREASING:Alkaline De – Greasing is the process to remove Grease and oil film.
PHASE – II – ACID PICKLING:

The purpose of carrying out acid pickling is to remove Mill Scales, welding slag, iron oxide, sometimes-siliceous impurities and other extraneous matters.

PHASE – III – PASSIVATION:

The pickled surface can be easily passivated. The aim is to form a coherent, adhesive, non-porous, thin layer of gamma-ferric oxide. The layer is formed under expansion and hence is passive and protective.

PHASE – IV – HIGH VELOCITY HOT OIL FLUSHING:

We provide unique oil flushing service, using oil-flushing skid developed to increase operating efficiency and reduce timescales. This equipment, and our team of experienced technicians, provides an effective and highly economical service onshore, offshore, overseas, for the rapid and effective clean up of lube, seal and hydraulic oil systems. Our equipment is compact, transportable, electrically driven and configured to work in hazardous areas. After setting the system up for a high velocity flush by removing all restrictions to flow, operational oil will be flushed through the system. This high volume of oil will remove scale and particulate from the piping and flush it back to the system where it will be filtered. Thermal shocks to the system will greatly enhance the cleaning process. Super Clean Oil is simply a by-product of this process.

CERTIFICATION:

We provide on-site certification of contamination levels to NAS 1638 and ISO 4406 using on line laser particle counter.

With the use of an On Line Laser Particle Counter, particle counts may be accomplished on site in a matter of minutes giving actual counts. All counts are based on particles per 100 ml, in various sizes (i.e.). 5-10 micron, 10-25 micron. A minimum of 100 ml of oil will be required for analysis.
