Pipeline Flushing; Pressure Test; Start-Up - Samson 43-1 Mounting And Operating Instructions

Mounting and start-up
6.3.5

Pipeline flushing

We recommend additionally flushing the
pipeline with installed regulator before start-
up.
Î See Fig. 6
Î Observe the mesh size of the upstream
strainer for the maximum particle size.
Use strainers to suit the process medium.
Î Check the strainer for dirt each time the
pipeline is flushed and clean it, if neces-
sary.
If the regulator malfunctions due to clogging
after flushing the pipeline, proceed as de-
scribed in Table 8.
6.3.6

Pressure test

Note
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.
NOTICE
!
Risk of valve damage due to a sudden
pressure increase and resulting high flow
velocities.
− Slowly open the shut-off valves.

6.4 Start-up

Re
DANGER
!
Risk of personal injury due to process me-
dium escaping under pressure.
− First start up the regulator after mounting
all parts.
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.
Wear protective clothing and safety gloves.
Once installed in the pipeline, the regulator
can be put into operation.
Î Open the shut-off valves (1, 6) slowly
preferably starting from the upstream
pressure side.
Î Avoid pressure surges.
Î Check the adjusted temperature set point
at the thermometer (4) installed near the
temperature sensor.
