NOMENCULATURE OF APPENDIX-P

TANK NOZZLE DISPLACEMENT:

NOZZLE CHECK AS PER API 650:
* For external piping connected to tanks can be used for Tanks size greater than 36m (120 ft) in diameter.
* The purchaser can decide for the Tank size 36” and smaller as per API 650 design
* The recommendations of this appendix represent accepted practice for the design of shell openings in the lower half of the bottom shell course that have a minimum elevation from the tank bottom and meet the requirements of Table 5-6.

SHELL DEFLECTION AND ROTATION

1- Radial Growth of Shell
The unrestrained outward radial growth of the shell at the centre of the opening connection resulting from product head and/or thermal expansion shall be determined as follows:

2- Rotation of Shell
The unrestrained rotation of the shell at the centre of the nozzle-shell connection resulting from product head shall be determined as follows:

The allowable Nozzle load can be calculated as per Appendix P- (p.2.7) or the allowable loads can be used which will be furnished by Vendor/ Mechanical Static.
