[MW:23666] Re: PDR for a SSWOL nozzle fitted to an ASME -VIII Div1 vessel // UG-11(c)

Since it is a standard product (LWN Flange), assuming  WOL is not part of strength calculations, going by UG 11,  Parts furnished under the provisions of (b), (c), and (d) need not be manufactured by a Certificate Holder. In my opinion  The nozzle could be furnished under the provisions of UG-11(c) as a manufacturer's standard in which case all of the rules in UG-11 as applicable to this construction shall be met, including establishing a pressure-temperature rating.

Thanks, Mr Raghuram,

But what I see in the link is related to WOL flanges (fittings) and in the attachment I sent, it clearly says they are exempt. My question is regarding SSWOL seamless nozzles. Most of the postings say PDR is required for flanges, but ASME reply says NOT REQUIRED.

Will seamless SSWOL nozzles need a PDR, please advise.

Dear Raghuram,

A few days ago, I had posted in this blog a query regarding requirement of PDR for a SSWOL nozzle fitted to an ASME -VIII Div1 (2013)

vessel, but did not receive any reply from any of the members.

Please advise me referring to the attached reply from ASME sent to our Welding Engineer by ASME Standards and Certification Engineer.

Since this Code reference is for 1989 Ed, and I do not have it, I would appreciate if you could give your best judgement whether we need PDR.

Please excuse my writing to you personally, but in the interest of the subject matter, I hope you will help me out.    

BR,
