GENERAL NOTES : A. PIPING VENTS, DRAINS AND SAMPLE POINTS ARE 3/4” MINIMUM. FOR VENTS AND

DRAINS, ANY HORIZONTAL VALVE ON THE THE RIGHT HAND SIDE OF THE VERTICAL PIPELINE IS TO BE READ AS A DRAIN VALVE AND ANY HORIZONTAL VALVE ON THE LEFT HAND SIDE OF THE VERTICAL PIPELINE IS TO BE READ AS A VENT VALVE CONNECTION.

B. ALL VALVE CONNECTIONS TO ATMOSPHERE IN PROCESS SERVICE WILL BE

PROCESS LINE

PLUGGED OR BLIND FLANGE.

C. THE RESPONSIBILITY OF ADMINISTRATIVE CONTROLS FOR VALVES NOTED CSO,

CLOSED DRAIN PIPING SPEC. CLOSED DRAIN SUB-HEADERS AND HEADERS ARE SEGRAGATED FOR EACH PIPE RATING CLASS IN LINE WITH PROCESS PIPING UP TO CLOSED DRAIN DRUM NOZZLE. ON A CASE BY CASE BASIS SOME DRAINS/VENTS COULD BE COMBINED UPSTREAM CHECK VALVE AND POSITIVE ISOLATION (PRESSURE, SERVICE, MAINTENANCE SEQUENCE COMPATIBILITY REVIEW).

DISTANCE 600MM MIN IS ONLY REQUIRED IN CASE OF COLD DEPRESSURIZATION TO AVOID ICING OF THE BLOCK VALVE.

POSITIVE ISOLATION TO BE SELECTED AS PER TABLE ON RLNG-000-PR-PID-0011 DEPENDING ON SERVICE AND LINE SIZE DIAMETER.
