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 installed
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.
Tip
5.4.2 Pressure test
The plant operator is responsible for
performing the pressure test.
SAMSON's
After-sales Service can support you to plan
and perform a pressure test for your plant.
Risk of regulator damage due to a sudden
pressure increase and resulting high flow
velocities.
Î
Slowly open the shut-off valves.
During the pressure test with installed regula-
tor, make sure the following conditions are
met:
Î
The maximum test pressure does not ex-
ceed 11 bar.
Î
The largest set point at the pilot valve is
adjusted.
If a pressure test of the plant is to be per-
formed with 1.5 times the pressure rating of
the safety shut-off valve, the regulator must
be removed and a suitable length of pipe in-
stalled in its place before testing.
