a) High point bleeds are to be installed at all high points in the system piping. 1/2” x 12”
nipples welded in the top of the piping with ball valves & plugs attached are to be used.
b) It will save a considerable amount of time during the cold filtration if the thermal system
piping is cleaned prior to assembly.
c) The mill scale (the results of oxidation) on the inside of the piping as well as construction
debris can foul the oil and cause the need for the filters to be cleaned more than need be.
This can range from simply using a rag to ordering pickled pipe. (“Pickling” is a process
