AMMONIA PIPE ABBREVIATIONS:

 

Abbreviating the names given to pipes in the ammonia refrigeration system will assist the operator in identifying and tracing the system. To further assist the operator make sure the physical state (LIQUID or VAPOR) as well as the pressure level (HIGH or LOW) are also identified in the marker. i.e., Adding -10° to a particular recirculated suction line and 0° to another one, would serve to differentiate between 2 Low Temp Recirculated Suction (LTRS) lines.

DIRECTIONAL ARROWS

Directional arrows will be printed on the marker body. In the case of the wrap around pipe markers, arrows & legends are printed repeatedly in opposite directions allowing the marker to be applied in any direction achieving proper reading while indicating pipe content flow. The "self-adhesive" type of marker will be printed with one directional detachable arrows. In either case, the directional arrow or arrowhead will be BLACK in color and proportionate in size to the marker. Directional arrow tape may also be applied around the full circumference of the pipe.
