r6155 - I'm a bit confused as to why you say that the design is not allowed by ASME. Perhaps you could provide some clarification as I have seen numerous ASME Code compliant configurations for attachment of a tangential nozzle.
tangential nozzle is welded to shell per UW-16 (d)
wear plate...
Can anyone provide me at sketch/detail for welding a 3" x 0.438 wall tangential nozzle into a 132" OD x 0.375" wall shell and haveing a 0.25" all arond inside diameter wear plate. Code is ASME Section VIII, Div. 1.
Thank you in advance
Are there any limitations (cone angle, full penetration weld, etc.) per ASME Section VIII, Div. 1 on welding (large end to shell) a conical nozzle to the side (not end)of a shell?
Restoration by encapsulation without removal of the degraded area is accepted by the National Board Inspection Code (NBIC) as restoration by Alteration. This method of restoration can be very cost effective as the degraded area does not have to be removed thus saving fit-up, welding, and...

You have several options:
1. Perform and document an analytical "Fitness for Service" evaluation showing compliance with ASME Section VIII, Div. 1, exist in the current condition.
2. Internal Weld Build-up repair of degraded area to original condition.
3. External Weld Build-up repair...
I AM FULL PENETRATION WELDING 1/2" THK P1 MATERIAL TO P5A MATERIAL AND USING A BACKING BAR. CODE IS ASME B31.1. BOTH BASE MATERIALS HAVE CARBON < 0.15% TO AVOID POST WELD HEAT TREATMENT. BACKING BAR WILL P1 MATERIAL
QUESTION: IS IT A CODE REQUIREMENT THAT THE P1 BACKING BAR MATERIAL ALSO...
If both methods used follow the design process (prepare, check, independent verification)of the applicable QA Program and both provide acceptable results for compliance with ASME criteria (Design by Analysis using FEA and and Design by Rule using hand calculation), I should think that the 2...
For repairs/alterations in the field - the National Board Inspection Code (NBIC) allows for this type inspection. It is addressed in a NBIC Interpretation 01-15
