SpectraSensors recommends using 1/4 in. O.D x 0.035 in. wall thickness,
seamless stainless steel tubing. Refer to the system layout drawing in
Appendix A for supply and return port locations.
To connect the sample supply lines
1. First confirm that each sample probe is correctly installed at the
process supply tap and that each sample probe isolation valve is
closed.
2. Also, confirm that each field pressure reducing station is installed
properly at the sample probe and that the pressure regulator at each
field pressure reducing station is closed (adjustment knob turned
fully counterclockwise).
3. Check that each relief valve vent line is properly installed from the
field pressure reducing station to the low pressure flare or
atmospheric vent connection.
4. Determine appropriate tubing route from the field pressure reducing
station to the SCS.
5. Use stainless steel tubing rated for the specified supply pressure
shown in Appendix A. Run the tubing from each field pressure
reducing station to the corresponding sample supply port of the SCS.
6. Bend tubing using industrial grade benders, check tubing fit to
ensure proper seating between the tubing and fittings.
7. Fully ream all tubing ends. Blow out the lines for 10
to
15 seconds
with clean, dry nitrogen or air prior to making the connection.
8. Connect each sample supply tube to the SCS using the 1/4 in.
stainless steel compression-type fitting provided.
9. Tighten all new fittings 1-1/4 turns with a wrench from finger tight.
For connections with previously swaged ferrules, thread the nut to
the previously pulled up position, then tighten slightly with a wrench.
Secure tubing to appropriate structural supports as required.
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.
