5.4 Testing the regulator
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure equip -
ment that may burst when handled incor -
rectly. Flying projectile fragments or the re-
lease of compressed medium can cause seri-
ous injury or even death.
Before working on the regulator:
Î
Depressurize all plant sections concerned
and the regulator.
Î
Drain the process medium from all the
plant sections concerned as well as the
valve.
Re
Risk of personal injury due to process me-
dium escaping under pressure.
Î
First start up the regulator after mounting
all parts.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the
process medium and the operating condi-
tions.
Î
Wear hearing protection when working
near the regulator.
DANGER !
DANGER !
WARNING !
Risk of burn injuries due to hot or very cold
components and pipelines.
Depending on the process medium, valve
components and pipelines may get very hot
or cold and cause burn injuries.
Î
Wear protective clothing and safety
gloves.
SAMSON regulators are delivered ready for
use. To test the regulator functioning before
start-up or putting back the regulator into
operation, perform the following tests:
5.4.1 Leak test
The plant operator is responsible for per-
forming the leak test and selecting the test
method. The leak test must comply with the
requirements of the national and internation-
al standards that apply at the site of installa-
tion.
SAMSON's After-sales Service can support
you to plan and perform a leak test for your
plant.
1. Slowly open the shut-off valve (1) in-
stalled upstream of the regulator.
2. Apply the required test pressure.
3. Check the regulator for leakage to the at-
mosphere.
4. Depressurize the pipeline section and
valve.
5. Rework any parts that leak and repeat
the leak test.
