NOTES:
  1. NOZZLES ARE TAKEN WITH FLANGES TO GOST 12820-80, DESIGN 1 TO 12815-80, FOR NOMINAL PRESSURE PY = 1.6 МPа FOR SHELL NOZZLES AND PY = 0.25 МPа FOR ROOF NOZZLES, UNLESS OTHERWISE STATED IN COLUMNS 4 AND 10 OF THE SPECIFICATION.
  2. MANHOLE AND NOZZLE LOCATION IN THE PLAN (CORNER a º) AND THEIR ELEVATION (SIZE А) MAY BE CHANGED BY THE DESIGNER MINIMALLY TO FULLFILL THE REQUIREMENTS REGARDING DISTANCE BETWEEN THE ATTACHMENT WELDS AND SHELL WELDS.
  3. IF THE LOCATION DATA ARE NOT AVAILABLE IN THE SPECIFICATION (COLUMNS 6…9), COLUMN 6 (CORNER a º) WILL NOT BE FILLED BY THE DESIGNER, AND COLUMNS 7…9 (SIZES А, В, С) WILL BE FILLED IN ACCORDANCE WITH MINIMUM DESIGN REQUIREMENTS.
