Problem:
How to add a nozzle in AutoPIPE Vessel?
Solution:
How to model the Nozzles:
Follow The below Steps,
Step 1: Once equipment modelled (Pressure Vessel, Tank or HX), select Insert<Nozzle from main menu.
Step 2: fill the nozzle properties as per your requirements.
Use the Nozzle Type and Identification field to choose type of nozzle and add the details. Also, you can choose the type of flange through the Edit Flange option.
Fill the Diameter and Reinforcement cells correctly.
Use the Offset, Orientation, Inclination fields to specify the values you want to enter to locate the nozzle appropriately.
Once you complete the steps, nozzle will get added on the equipment, you can modify the details as per your requirements by clicking on the nozzle tag from component list from left side.
WRC:
In the Vessel properties, choose WRC as the Local Load Method. It will ONLY affect the nozzles. Other components (saddles, lifting accessories, legs, etc) have an option method in their own dialog

Question:
How to model a RTJ (Ring Type Joint) or other specific type flange face configurations?
Answer:
At "Nozzle Properties" in the "Edit flange" option AutoPIPE vessel provides flange "Type" options but no flange Facing option. When selecting a standard flange according to the applicable code (e.g., B16.5), the rating is determined solely by the flange material, design pressure, and design temperature. The facing of the flanges and the type of gasket do not influence the flange rating, shell calculation, or nozzle wall thickness calculation.
However, if you choose to fully design the flange, the gasket type and material will impact the calculations, which is not the case with standard flanges. Another words, the schedule of the nozzle does not affect the flange rating. Additionally, the gasket has no effect on the nozzle schedule. However, if you are using a welding neck flange, the thickness of the hub connecting to the nozzle will match the nozzle's thickness.
To perform flange calculations using standard flange dimensions and your preferred gasket type and material, check the Flange Calculation box in the Nozzle Flange dialogue box, then select Edit Flange and choose your Ring Joint gasket. This will enable the flange calculations. Please refer to the image below.
As mentioned earlier, you can select a standard flange and then use the Edit Flange option to check the Flange Calculation box. Once you select Edit Flange, the software will treat it as a body flange and perform flange design calculations using the dimensions of the standard flange. Refer to the screenshot below for guidance.
AutoPIPE Vessel currently does not support modelling a pair of flanges on nozzles. However, you can still perform flange design without adding any counter flanges to the nozzles.
