Hi Guys, I'm on the design of an Air Cooled Heat Exchanger as per ASME SECT VIII Div.1, 2015. This design is based on an existant Air cooler that need to be replaced. I Already designed the Headers per appendix 13 but I am little bit lost on the selection of plug for the plug sheet. The...

Thanks Ben. I agree whith your point, U-3 is about referenced standards an not necesarily the only acceptable standards. It´s logical to me using B36.19 latest edition, also with others ASME standards that are not in U-3, even whe the code doesn't stablish an specific edition. I'm not sure...

Hi Guys, I'm working with ASME Section VIII Div 1, 2015 Ed and it has caught my attention when on the table U-3(Year of Acceptable Edition of Referenced Standards) I did not find ASME B36.19M (Stainles steel pipe). a) What does this mean? b) Was ASME B36.19M (Stainles steel pipe) on Section...

Thanks, Can you send me a pic of Fig UG-34 (g) from 09 Addenda?

Hi guys I'm trying to make comparisons with Sec VIII div 1 2015 and Sec VIII div 1 2007 add 09. I want to know the difference con UG-34 (g) between both editions but I don't have the 2007, add09. Can somebody help me to identify the difference?

Hi GenB, which rules do you refer? Thanks

yes, UG-34 (d)(6) says that is attached by groove as shown on the figure but I still don't understand how is that groove. It doesn't seen a regular groove the land seems too big that is not possible to deposit to fill the weld. If you can help me to understand I really would appreciate that hehe

here is the attachmenthttp://files.engineering.com/getfile.aspx?folder=2e6bbd94-53db-47b1-9c94-314bcc370802&file=UG-34_(g).jpg

Hello, Basically I don't understand the figure UG-34 (g). I am not clear on how is the joint and how should be perform the welding according to figure UG-34 (g). Please check the yellow rectangle on the attachment. Is that a J-type groove? is tw the land? If is the land it looks so big that...

good. Thanks

When you say is a design variable you mean that is a process design variable? because the mechanical design is changing when I change the original material to other with different metallurgy

or this is not a necessary scenario?

change*

Yes, this was the MDMT when the tubesheet was in CS but now is duplex and this should cange, inst it?

Mmmm ok ok let me check. by the way my main doubt is about impact test for a tube sheet, my thickness is 2,874" the material is SA-182, MAWP 151 psi, design temperature 151°F, the MDMT I picked first is 32°F but I Know is high for duplex (I pick this value because was the original MDMT for a CS...

but can I stablish this factor under SEC VIII div 1 o just for process data?

I want you to help me how to select an MDMT for a duplex stainless steel SA-182 according to Sec VII div 1. When I have a carbon steel is easier to me but when I go to part CS but in this case I'm a little lost when I go to UHA. Which parameters of the design I need to know the MDMT? As you...

I want to know if I can find this swage (See attachement) in any Asme Standard. In B16.9 doesn't appears. I want to order this item but before order it I want to know if there is a standard for it or other name...

Hi guys, I have a design per appendix 13 but I want to know if I can model it on COMPRESS or other software. Ithe answer in COMPRESS is yes, I would like your help. Thanks, regards.
