Hi Guys,

I have to use 900 NB nozzle in one of the Pressure Vessel I am designing.

I would like to know how can we add a 900 NB nozzle into the Pressure Vessel.

Is there any other way of adding a 900NB dia customised nozzle into the Pressure Vessel.

Any doubts let me know.

Please guys help me out in this.

Thank You,

2 of the possible options are listed below. Other may be possible.

1st Option: In nozzle design dialogue, select "Thickness Basis" as "Actual". Enter OD or ID of nozzle and enter actual nozzle thickness to be used in the field next to corrosion allowance. It is recommended if you are using pipe, then consider mill undertolerance while entering actual thickness.

2nd Option: If your nozzle database is selected as "Metric Standards R64", then based on different schedule you can design nozzle 900 NB and also higher size too from "Diameter" selection option.

Regards,

Mukesh

Hi Mukesh,

Thanks for your help.

Hi Chandanraj,

If you want to use 900NB dia. customised nozzle, you can use the FVC self reinforced integral nozzles. This facility is available in PV Elite Nozzle dialogue. You can also check the FVC catalogue for various self reinforced nozzle sizes & ASME B16.5 flange classes.

In PVElite, you can also design HUB type self reinforcement nozzles, by using nozzle dialogue. You can input hub thickness/ Bevel angle for your required nozzle size. You have to select the 900# flange from the flanage menu, & can check the analysis.

As per ASME B36.10; 900NB(SI) is 36"(Customery). In nozzle design dialogue, select "Thickness Basis" as "Actual"; Enter OD or ID of nozzle diameter basis; Enter nozzle thickness assumed for calculation.
