a) All unauthorized personnel are excluded from water exit area prior to starting
flushing.
b) All personnel carrying out the Water Flushing operation shall be fully understood
their tasks and ensured by suitable protective equipment: i.e. ear protection, gloves,
and goggles as a minimum.
c) Hold toolbox meeting in the field involving all concerned personnel to remind again
the safety measures and objective of the activities.

disciplines working in associated area.
e) The area of the water exit should be roped off and clearly marked with warning
notices and kept free of personnel.
f)
Particles with water exiting the piping could be injured people and damage nearby
equipment. Adequate protection has to be installed and every attempt should be
made to have the area abandoned prior to Water Flushing.
g) Ensure an effective communication system connected between those responsible
for the operation and safety personnel. The suitable communication exists between
the water supply point operators and dumped out area operator.
6.

EXECUTION
7.1
Pre-Work of Water Flushing
a)
Prior to Water Flushing, ensure that all the remaining works after pressure test have
been cleared.
b)
In principal, the Water Flushing shall be carried out sequentially. i.e. first common
header then sub-header and finally branch lines.
c)
Water shall flow from top to bottom if applicable.
d)
Water Flushing sequence will be made according to construction progress or
geographical or functional criteria and also considering site requirements such as
availability of facilities, configuration of the lines or the devices to be removed etc.
e)
All other lines connected to each unit not ready for Water Flushing shall be isolated
until release for ready to flush. Installation and removal of blinds will be controlled by
blind list.
f)
Dead ends shall be cleaned separately. Remove end blind flanges and make hand
cleaning for the short dead ends.
g)
Following Devices included in the flushing system shall be removed as follows.
l
Control Valve

impulse pipe itself and whenever possible, shall be disconnected.
l
Rotating machines such as pumps and compressors by in/out isolation valves or
temporary blinds.

Static equipment such as columns, drums which are contained internals are not
able to use air holding purpose. However no internals installed vessels, hold-up
vessels can be used for downstream lines cleaning after the upstream of the
equipment cleaning is completed.
l
i)
Special equipment such as desuperheaters, heating coils, etc.
Removal of ball/gate valves is normally not necessary since these valves do not
restrict the flush flow path. These valves should be kept in the full open position while
flushing.
j)
Each flushing condition should be checked in advance. Any big remaining works that
will hinder the Water Flushing activity shall be coordinated to concerned discipline.
k)
During Water Flushing operation, large quantity of water with sand, particles of rust,
etc. will be spread out near flush-off point. Therefore, equipment and devices shall be
protected properly nearby water flush-off point. These foreign materials might damage
or contaminate the devices or equipment.
l)
In case of using permanent pumps, the suction line of the pumps should be cleaned
in advance and the suction strainer has to be installed.

Once all preparation work is completed, pre-commissioning supervisor shall inspect the
site and check that all protections are installed properly for water flushing.
Generally, Continuous circulation of water and filling and dumping water are applied to
flush the piping system in accordance with the site condition such as the availability of
water source, pipe configuration and size, flushing schedule etc.
7.2.1
Continuous Flushing
This type of flushing normally involves taking a section of piping and flushing is
from a “start-point” to an open end.
In general, the brief continuous flushing of water is as follows
a)
The water to be connected from the source with temporary hose, pipe or
permanent line.
b)
The water should be supplied continuously from its own flow or required
temporary pump.
c)
Open the block valve located on water source to make the continuous flow or
operating the pump.
d)
Downstream of water should be routed to disposal point.
e)
Cooling water lines can be flushed by using permanent pumps. In this case,
the pump shall be operated by minimum by-pass line.
7.2.2
Water Filling and Dumping Out
Filling and dumping water flushing is often used for cleaning vessels and hook-up
piping attached to the vessels.
In general, the brief Water Filling and Dumping Out is as follows
a)
The water to be connected from the source with temporary pipe, hose or
permanent line.
b)
After water is ready, fill the water into vessel.
c)
During fill the water into the vessels, dumping out point should be closed.
d)
Dumping out point should be routed to disposal area.

7.3
Allow the water to enter the system to be cleaned by opening the block valves.
Acceptance Criteria
The acceptance criteria will be visual inspection of discharged water. When any foreign
materials interfering with actual plant operation are no longer visually detected at the
water discharging point, the water flushing shall be deemed satisfactory completed.
7.4
Post Work of Water Flushing
After the Water Flushing operations of the system, pipe, valves and fragile devices have
to be reassembled.
a)
Fragile devices removed from Water Flushing operation as described in Paragraph
7.1 shall be reinstated.
b)
Used temporary gasket must be replaced with permanent gaskets.
c)
Threads is checked carefully and cleaned before reassembled.
d)
A special attention is required during rotating equipment is reinstated to avoid
misalignment.
e)
The orientation of check valves, globe valves, etc. shall be checked against the
direction of flow.
f)
Specific In-line instruments shall be installed by instrument specialists according to
the relevant drawings.
g)
Temporary blinds installed for Water Flushing shall be removed.
h)
Temporary valves for Water Flushing are to be replaced by permanent valves and
spool.
