PARAGRAPH / SECTION NO: 2.1 & 7.2.1

TITLE: Thermowells Install (VR19-0051)

QUESTION:

This work item describes the requirement to install thermowells in the condenser inlet and outlet pipes.

Reference 2.1 S9516-AA-MMO-000, Ship’s Stores Refrigeration Plant is the tech manual which does not address the condenser inlet and outlet piping. The tech manual page 1-3 addresses only thermometers for the Freeze Room, Chill Room, Compressor Suction and Suction Discharge. No Piping.

Is there a drawing available that addresses the condenser inlet and outlet pipe so we can determine thermowell and thermometer sizes, material and installation location in the pipes per the specification?

ANSWER: Install the standard Navy style 'lollipop' thermometers on the SW Inlet & Overboard for each of the three (3) reefer plants. These would be installed in a dry well fitting, should be welded directly to the pipe (CUNI 5").
