GENERAL NOTES: GENERAL NOTES:

1. PLATFORM ACCESS TO BE PROVIDED FOR MANWAYS AND EQUIPMENT WHICH CANNOT BE ACCESSED FROM GRADE.

PERMANENT PLATFORMS ARE REQUIRED WHEN THE PLATFORM STRUCTURAL SUPPORT MEMBER ALLOW A CLEARANCE OF 7’-3” (2200 MM) OR GREATER ABOVE GRADE. TEMPORARY OR PORTABLE PLATFORMS ARE REQUIRED WHEN THE CLEARANCE BETWEEN PLATFORM STRUCTURAL SUPPORT MEMBERS AND GRADE WOULD BE LESS THAN 7’-3” (2200 MM).

2. MATING PIPING/VESSEL FLANGES USED FOR INSTRUMENT CONNECTION SHALL BE OFF SAME FLANGE

CLASS AND FINISH AS THE FLANGES SPECIFIED FOR THE INSTRUMENTS.

3. FOR PROJECTS WHERE METRIC UNITS ARE SPECIFIED: ALL DIMENSIONS ARE IN MILLIMETERS UNLESS

UNLESS SPECIFICALLY NOTED OTHERWISE.

NOTES:

1. DEFINITION FOR PIPE ROUTING GUIDE WORDS

A) NO POCKET

THE PIPE SHALL NOT HAVE ANY LOW POINT, SO AS AVOID ANY LIQUID ACCUMULATION.

B) NO VAPOR POCKET

THE PIPE SHALL NOT HAVE ANY HIGH POINT, SO AS AVOID ANY VAPOR ACCUMULATION.

C) FREE DRAINING

THE PIPE SHALL BE DESIGNED SO AS TO MAKE THE LIQUID DRAIN FREELY TOWARD THE SPECIFIED DIRECTION.

D) SLOPE

THE PIPE SHALL BE CONTINUOUSLY SLOPED IN THE SPECIFIED DIRECTION WITH AT LEAST THE DESIGNATED SLOPING RATE.

E) GRAVITY FLOW

THE PIPE SHALL BE ROUTED SO AS TO ALLOW GRAVITY FLOW OF THE FLUID ALONG THE FULL LENGTH OF THE CIRCUIT.

2. HIGHER RATING COMPANION FLANGE SHALL BE APPLIED FOR THE RATING BREAK POINT.

3. THIS SYMBOL IS USED IN EACH P&ID.

1

4. HIGH POINT VENTS AND LOW POINT DRAINS USED FOR HYDRAULIC TEST PURPOSES ONLY ARE NOT SHOWN ON P&ID.

5. ALL VENTS, DRAINS AND BLEEDER VALVES ARE SCREW-CAPPED OR BLIND-FLANGED AS PER PIPING SPECIFICATION.

6. ON P&IDs, P&ID NUMBERING IS ABBREVIATED INTO XXXX-YYYY
