1.0 INTRODUCTION
The purpose of Lube oil flushing is to ensure cleanliness of lube oil system in rotating
equipment prior to Commissioning and Start-up. It is important and mandatory to
remove foreign materials (dust, debris, organic material, welding waste, etc.) which
might enter during fabrication and installation for reliable operation of rotating
equipment.

PRE-REQUISITED LUBE OIL FLUSHNG
1) All oil serviced piping must be hydrotested and pre-cleaned by air blowing.
2) Oil reservoir, flanged pipes, manholes, removable headers, filters, coolers, temporary by
pass piping and so on shall be opened and inspected internally for cleanliness.
3) Accessible welds on pipes and fittings shall be inspected to remove slag.
4) Internal surfaces of component parts of field fabricated lube oil system shall be cleaned by
air prior to lube oil flushing.
5) Electricity for running Auxiliary lube oil pump and electrical heater (or temporary heater)
shall be available. In case temporary generator is used, the earthing system and any other
protection device (such as temporary MCC) shall be prepared and fully operational prior to
power up.
6) Make sure all flange joints are properly tightened to prevent any leakage during the activity.

LUBE OIL FLUSHING PROCEDURES
The following method is a general test method of Lube Oil Flushing. If Vendor’s
procedures are available, Vendor’s procedure shall be prevalent.
7.1
Planning
Planning the cleaning circuit;
1) Temporary hose connection and cross-over positions
2) Temporary mesh or strainer check point
3) Temporary blind locations

4) In-line instrument to be removed
7.2
Preparation
1) Ensure to barricade & put signage in order to protect the equipment from an
unauthorized people enters the area.
2) Ensure cleanliness of the oil reservoir from dust by sponge and/or industrial vacuum
cleaner. Sponge and other tools must be clean to prevent any contamination.
3) All flanges to prepare drip pans at all times during the activity for any leakage.
4) Take out the permanent filter element and orifice (removing orifice is for higher
velocity).
5) Mount wire mesh at lube oil return line before oil reservoir in order to catch the foreign
matters. Wire mesh can be installed between flanges, otherwise in the wire box made
on purpose. Specific wire mesh installation location is based on the loops as per
vendor procedure/instruction.
6) Install temporary piping by passing the main equipment such as compressor, pump.
7) Insert blind between lube oil flange and equipment flange to protect equipment to
prevent the lube oil from entering the main equipment bearing housing during first oil
flushing.
8) Ensure installation of temporary piping and blind is properly tightened.
9) Fill the reservoir with lube oil. Required amount is 60~70 percent of reservoir capacity.
(Slightly higher than Low level).
10) Remove in-line instrument like PCV, TCV, Thermometers and etc.
11) Heat the flushing oil up to 50~70℃ by turning on electric heater. Temperature will be
measured by temperature gauge and potable temperature gun.
Field operator must check as below before turning on electrical heater:
7.3

Check Proper barrier & Signage ‘Caution Hot Surfaces’ and ‘Unauthorized Entry is
prohibited’.

Check cable connection to equipment which should be connected with molded lug
and soldered lug.

The laying of cable should performed after taking the measures to protect damage of
insulation and to avoid contact with water, oil, steel cables and hot pipelines.

The connection of cable should be conducted by qualified electrician.

Fully supervise and monitor oil temperature through temperature gauge during
heating up of oil until completion of work.

1) Install a bypass line of bearing housing of main equipment.
2) Blinds should be installed at main equipment’s flanges to avoid rust entering the main
equipment. To make sure block valves (Close position) are available upstream of the
main equipment with blind install.
3) Check that the permanent oil filter element and temporary wire mesh are installed as
per the plan.
4) Circulate the lube oil through bypass line and keep the proper lube oil temperature
during the lube oil circulation in accordance with vendor recommendation.
5) Careful hammering is to be done on a regular basis in order to remove the slag.
(Hammering must be concentrated on the welding part and wrapping bend part of the
pipe)
6) Check the bellows during the lube oil flushing.

Lube oil temperature

Check the operation of oil flushing

Abnormal of the oil and overheating of the heating equipment

Check the any leakage of oil
7) Check the temporary wire mesh periodically and write down state of the accumulated
foreign matters. If foreign material found at the strainer and it is out of acceptance
criteria, the lube oil flushing activity should be repeated.
7.3.2 Final oil flushing
1) Remove temporary piping
2) Blinds should be installed at main equipment’s flanges to avoid rust entering the main
equipment. To make sure block valves (Close position) are available upstream of the
main equipment with blind install.
3) Clean pump suction strainer, install permanent filter element (new), clean wire mesh
on the lube oil return line and wire mesh between lube oil inlet flange and bearing
housing flange.
4) After removing the temporary piping, it is necessary to mount permanent piping and
check them for possible oil leaks.
5) New lube oil refilling (only if the lube oil is contaminated or recommendation by
vendor). If analysis of oil sample is within acceptance criteria, flushing oil will be used
for operation. Flushing oil shall be proved as clean by oil analysis report including
physical inspection.
6) Establish lube oil circulation and check the lube oil temperature.
7) Confirm normal operation pressure and Check oil leakage.
Note: Lube oil used for lube oil flushing is same as normal operating lube oil or
specified/approved oil by vendor.
