all the jobs have been completed. The form in itself is a
reminder for the foreman/ mechanic and a record for
operations. Please indicate the date when the job was
completed on the blank provided. ~
A. Flow control valves
Inspection of control valves is to include verification of full travel stroke of the valve. Also valve components such as packing bolts, top works, positioner, tubings, etc. are to be in good working order.
For items 1-6 inspection will include pressure checking the signal tubing from the controller to the control valve.

______ 4. Inspect reactor vent flow orifice plate.
______ 5. Inspect N? to 0? riser orifice plate.
______ 6. Inspect N? to mixed feed header orifice plate.
_____ 7. Inspect 0? orifice plate.
D. Flow transmitters
Prior to zeroing flow transmitters the signal tubing
from the transmitter to the recorder/controller will be pressure checked.
______ 1. Zero and cal i brat e HCI. feed flow transmitter.
______ 2. Zero and cal ibrate organic.; to vaporizer flow trans mitter.

Check flush water rotameter.
Thermowells and thermocouples
When hooking thermocouples back up. verify by L&N change that the wire is being hooked to the right thermocouple.
1. Replace reactor dome thermowells and thermocouples. Check each thermowells for weld defects.
2. Rep 1 ace reap mi
ne-rmoweiis and thermocouples.
Check each thermowel1s for weld defects.
3. Inspect Rx vent Iine thermowel1 and nozzle for corrosion problems.
Pressure control valves
For the following items 1 be stroked and it should be fully open and fully closed controller output pressures
4 the control valves should verified that the valves are at their respective as indicated.
1- Inspect. overhaul, repack Dowtherm 3(o) - 7(c) valve.
2. Inspect. overhaul, repack Dowtherm 7(c) - ll(o) valve.
3 Inspect overhaul, repack Dowtherm ll(o) - 15(c) valve.
4 Inspect. overhaul, repack both Dowtherm 11 psig valves. Valves open, close at 11#.
For the following items 5 and 6 inspection is to include:
A. Pressure checking the signal tubing from the controller to the control valve.

2. Test run, repair L & N.
3. Inspect. clean, repair rotameters.
IMPORTANT NOTES
We need the blanks filled out on the pressure trans mitters proof test even if there was no difference from the desired settings.
When reconnecting the organics flow transmitter orifice plate impulse lines, check them for plugging problems. Drain any liquid (probably water) from the transmitter's impulse lines. Fill lines.
The deviation for the primary inlet transmitter is:+3.-3
If the need arise to pull a control valve, cover the flanges to prevent foreign material from entering the system
Check nitrogen selenoid valves for leak through at the bench
