Dear Members, I would like to know which paragraph in WRC-107/297 says/allows the use of reinforcing pad thickness while calculating the local stresses in a nozzle to shell junction in cylindrical shells or spherical dishes. The WRC code refers the "T" as wall thickness of cylindrical shells...

Dear Colleagues, Could someone please let me know how to calculate the MAWP of Tubesheet designed as per UHX. Regards Thaksen

Dear Members, This material is already used. What could be the possible remedy. The code to which the vessel is designed is VIII-Div-1 2010 Add2011. And in that this material is not specified. The addition was done in 2013 for S32760. Thanks and Regards

Please refer attachmenthttp://files.engineering.com/getfile.aspx?folder=5e9136f1-3a74-44bb-be55-2110e90081a1&file=SA-815.jpg

ASME SA815 WPS UNS S32750 is listed in SEC-II as "WPS32750 CRS32750 S32750". I have read the above and my interpretation is it tell " confirm to one of the specification" ie SA-815 and this is listed it does not limits the grade.

Dear Members, I would like to know if I can use fitting material of SA-815 WPS UNS 37250 for an ASME Sec.VIII Div.1 vessel. The complete vessel is of UNS 32750 with different ASME specifications. Is it true that I cannot use this material if this is not listed in the UHA-23 table of ASME...

Dear Eng. Members, My query is "what seismic importance factor shall be used while designing a lethal vessel(column)ground supported. If client specification says that the occupancy category is III then as per ASCE- Table 11-5-1 importance factor is 1.25. Does OC III includes hazardous...

Dear Members, we want to use S275JR in replacement of SA-283 C for structural parts of pressure vessel like skirt, base plate etc. But since this material is not listed in ASME SEC II PART-D, we are unable to use this material. I would like to know if S275JR material listed in ASME code or does...

Thank you Sir, for your valuable replies.

Dear's, The trunnion sketch as shown in the trunnion calculation page depicts the tunnion pipe is directly connected to the shell and in the WRC calculation the local thickness at the pipe OD (RM/t)is considered as repad+shell thickness. My query is shall the trunnion pipe be directly welded...

Dear's, Thanks for such a good help. But my query is still unanswered. As seen from the replies i would like to clarify that most of them had not got my query correctly...Let me rephrase..I am just in a need to know ways to shield radiography...and the arrangement shall be movable. We had...

Dear's, I am looking for a movable shield that I can use for radiography of pressure vessels using gamma rays. After making a search I was able to get few information. The material that I can use are concrete blocks, steel plates and steel plates lined with lead. My query is what is the best...

Dear's, I would like to know if it is possible to mark 2 MAWP @ 2 Temp on a same ASME Nameplate. The Vessel is single chamber and not multi chamber. I want to certify the vessel as per 2013 Div-1. I am aware that a range of MAWP is not acceptable as per Interpretation. Need your support...
