Nozzle to Shell Inside Fillet Weld Leg

Nozzle to Shell Inside Fillet Weld Leg

Nozzle to Shell Inside Fillet Weld Leg

(OP)
HI

I am designing pressure vessel as per ASME Sec VIII Div-1,having Nozzle passing thru vessel wall up to center line of vessel.
I have provide full penetration & fillet weld for Nozzle to shell attachment.
Is it mandatory to provide Nozzle to Shell Inside Fillet Weld Leg ?

RE: Nozzle to Shell Inside Fillet Weld Leg

Id sday no, unless calcualtions show that area replacement require them to be done to meet code requirements, or when the design envelope (drawings, calculations) provide such details as being mandatory.

RE: Nozzle to Shell Inside Fillet Weld Leg

Just to back up XL83NL's post.

Standard Designation: BPV Section VIII Div 1
Edition/Addenda:
Para./Fig./Table No:
Subject Description: Section VIII, Division 1, UW-16 and Fig. UW-16.1, Nozzle Fillet Welds
Date Issued: 09/24/1986
Record Number: BC84-169
Interpretation Number : VIII-1-86-89
Question(s) and Reply(ies):
Question (1): In Section VIII, Division 1 construction, is it acceptable to attach a nozzle neck that projects past the inner vessel surface [similar to Fig. UW-16.1 sketch (h)] with a full penetration groove weld and fillet weld on the outside only [similar to Fig. UW-16.1 sketch (c)]?

Reply (1): Yes.

Question (2): Would the use of the inside nozzle projection as reinforcement require an inside fillet weld?

Reply (2): No.

Thank you david339933 and XL83NL .

RE: Nozzle to Shell Inside Fillet Weld Leg

If you are reinforcing the nozzle using Appendix 46 (Div 2 rules), then you need to use div 2 weld details (App 46-3(f)), which require that there be an inside fillet weld.
Even if you are using Div 1 reinforcement rules, if the vessel is experiencing fatigue service, the fatigue assessment will require that there be an internal fillet weld.

A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
