5.5 Testing the regulator
DANGER
!
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 process medium under pressure can
cause serious injury or even death.
Before working on the regulator:
Î Depressurize all plant sections concerned
and the regulator.
Î Disconnect the control line.
Î Drain the process medium from all the
plant sections concerned as well as the
valve.
Re
DANGER
!
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
WARNING
!
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 valve. Follow the instructions
given by the plant operator.

WARNING
!
Risk of burn injuries due to hot or very cold
components and pipelines.
Depending on the process medium, the regu-
lator 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:
5.5.1
Leakage
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.
Tip
SAMSON's After-sales Service can support
you to plan and perform a leak test for your
plant.
1. Install the regulator into the pipeline. See
section 5.4.1.
2. Apply the required test pressure.
3. Check the regulator for leakage to the at-
mosphere.
4. Depressurize the pipeline section and
regulator.
5. Rework any parts that leak and repeat
the leak test.
