Connections to the
Supply
Use the following procedure to connect the sample supply line.
Consult the layout and flow diagrams in the system drawings. All work must
be performed by technicians qualified in pneumatic tubing.
Using 1/4 in. O.D x 0.035 in. wall thickness, seamless stainless steel tubing
is recommended. Refer to the system layout drawings for supply and return
port locations.
To connect the sample supply line
1.
First confirm that the sample probe is correctly installed at the process
supply tap and that the sample probe isolation valve is closed. Also,
confirm that the field pressure reducing station is installed properly at
the sample probe and that the pressure regulator at the field pressure
reducing station is closed (adjustment knob turned fully counterclock
-
wise).
2.
Check that the relief valve vent line is properly installed from the field
pressure reducing station to the low pressure flare or atmospheric vent
connection.
3.
Determine appropriate tubing route from the field pressure reducing
station to the SCS.
4.
Run stainless steel tubing from the field pressure reducing station set
for the specified supply pressure to the sample supply port of the SCS.
5.
Bend tubing using industrial grade benders, check tubing fit to ensure
proper seating between the tubing and fittings.
Process samples may contain hazardous material in
potentially flammable and/or toxic concentrations.
Personnel should have a thorough knowledge and
understanding of the physical properties and safety
precautions for the sample contents before installing the
SCS.
Consult sample probe manufacturer instructions for proper
installation procedures.
The process sample at the sample tap may be at a high
pressure. Use extreme caution when operating the sample
probe isolation valve and field sample reducing pressure
regulator.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
