Atmospheric Conditions – a typical hot and dry climate prevails with frequent sand

storms. The particulate atmospheric dust can be as small as 2 microns. Rain is an

infrequent occurrence, but on such occasions is heavy.

High humidity is not the normal case. Use minimum humidity as the design case.




APPENDIX- A2 - SELLER DOCUMENT REQUIREMENT LIST (SDRL)




APPENDIX - A3 - ALLOWABLE FORCES AND MOMENTS ON NOZZLES



ALLOWABLE FORCES AND MOMENTS ON NOZZLES

(EXTERNALLY APPLIED NOZZLE LOADS)

Each nozzle shall be designed to withstand the forces and moments specified in the following table. The effect on the shell or head due these externally applied loads shall be analyzed per WRC107/297 for each vessel.

With regard to the radial load (FR), calculations shall be made firstly with the force acting radial outwards in conjunction with the internal pressure and then with the force acting inwards. In the second instance, the internal pressure shall not be used to oppose the compressive stresses due to the force acting radial inwards; for this load condition a null pressure condition is to be considered to exist.

For nozzles in spherical shells, the forces FL and FC and moments ML and MC shall be combined algebraically to give resultant values.

Under vacuum condition, deflections (δ) shall be derived at locations adjacent to the nozzle to shell junction and shall be limited to:-

δ≤ 0.0025 R

Where ‘R’ is the shell or head radius.

FR = Radial Load MT = Torsional Moment

FL = Longitudinal Force ML = Longitudinal Moment

FC = Cirumferential Force MC = Circumferential Moment

Nozzle loads and moments shall be as per MUK-FAC-255.
