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 PLUGGED

OR TO HAVE BLIND FLANGE.

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

LO OR LC IS ACCEPTED BY OWNER. APPROVAL IS REQUIRED BY OWNER FOR ALL SUCH MEASURES.

NOTES :

VALVE TYPE IN ACCORDANCE WITH PIPING CLASS. FOR CONTROL VALVE OPEN BY INSTRUMENT AIR FAILURE (FO), ONE MAINTENANCE BLEED WILL BE INSTALLED UPSTREAM OF CONTROL VALVE. FOR CONTROL VALVE CLOSED BY INSTRUMENT AIR FAILURE (FC), FAIL LOCKED IN POSITION (FL) OR TOXIC, CORROSIVE SERVICE, TWO MAINTENANCE BLEEDS WILL BE INSTALLED, ONE UPSTREAM AND ONE DOWNSTREAM OF THE CONTROL VALVE FAILURE POSITION ACCORDING TO PID. IF HAND WHEEL IS INSTALLED, NO DOWNSTREAM MAINTENANCE BLEED IS REQUIRED. THE NEED FOR INSTALLATION OF BLOCK VALVES, BY-PASS VALVE AND HAND WHEEL AROUND THE CONTROL VALVE TO BE DETERMINED ON A CASE BY CASE BASIS BY PROCESS. SINGLE OR DOUBLE BLOCK AND BLEED AS REQUIRED. REFER TO ISOLATION PHILOSOPHY N° : RLNG-000-PR-PP-0003.

TOP OR SIDE CONNECTION. FOR TYPE OF POSITIVE ISOLATION REFER TO POSITIVE ISOLATION TABLE. HAZARDOUS SERVICES (INCLUDING HYDROCARBONS, EXCLUDING CHEMICAL) VENT TO FLARE AND DRAIN TO A CLOSED DRAIN SYSTEM. ALL DRAINS SHALL BE HARDPIPED TO FLARE HEADER OR DRAIN HEADER TYPE B1 REFER TO LEGENDS SHEET P&ID N° : RLNG-000-PR-PID-0013. DISSIMILAR TYPE CHECK VALVES. SPEC BREAKS TO BE DETERMINED ON A CASE BY CASE BASIS BY PROCESS. DISSIMIAR CHECK VALVES TO BE CONSIDERED IN CASE OF NITROGEN CONTAMINATION BY HYDROCARBON.
