Nozzle Loading of Axial Nozzle with Reducer Head

A sketch would help a lot...

Have you contacted the COADE people about your concerns ?

shape of axial nozzle. Thanks for action . :D.

Pressure vessels for topside process systems are such equipment

as Separators, Knock-Out Drums, Heat- Exchangers,

Scrubbers etc.

The nozzle loads from connected piping shall not cause

stresses in the nozzle-to shell interface to be larger than

allowed by the actual pressure vessel code. Typical pressure

Vessel codes are:

- ASME BPVC Section VIII, Rules for Construction of

Pressure Vessels

- PD 5500 Specification for Unfired Fusion Welded Pressure

Vessels

- EN 13445 Unfired Pressure Vessels.

Normally the allowable nozzle loads will be tabulated on the

vendors General Arrangement Drawing of the actual pressure

vessel. Some standards, like the NORSOK Standard R-001

Mechanical Equipment, have equations for allowable nozzle

loads that the operator and vendor can agree upon in a specific

project.

For the NORSOK Standard R-001, these nozzle load equations

are given in section 5.1.5 of that standard.

Looks good to me, weld it.

Hi,

it seems like special issue, but i have another solution, i tried before but it will need from you some experiance in the CAESER II sofware. i simulate the vessel as a rigid item with its material and process conditions and alos sput mu input regarding the desirable piping componant (nozzle, flanges) and make my analysis according to WRC 297.

it seems work. look to the below image which i got it from the application guide of the program, which describe this procedure step by step :).

.

another solution, according to the pressure vessel design manual " very interseted book" at the external loads on nozzle paragraph, there are another alternative method to the WRC 107 analysis, which is the MAximum allowable nozzle load regarding the flange rating. this method used as the connection point between the piping and vessel designers to limit the piping system loads and automatically know that the connected vessel shell or head is not overstressed.
