LOL...time for beer.

Thanks GR2VESSELS, but I am new in the area of insulation. I mean using tray, can there be heat passing through trays ?

Well if I am understanding it correct than UG-37 under ASME VII Div. 1 should provide with the limits of enforcement showing how far the pad is allowed togo around the nozzle. It is good engineering practice to have material for pad to be of equivalent strength as shell or greater. Does same...

Hey, We are vessel fabricators and have the vessel made of carbon steel. Customer wants internal insulation rather the external. Because of the grid supports being welded directly to the vessel, (as shown in the attached figure), there will be heat loss through grid support. Is there any...

Can someone advice on what Apply loading (reference PD5500:2006, Annex G.2) 1.Circumfrential bending moment due to a radial line load variation around circumference ? 2.Longitiudinal moment from radial line load variation around circumference ? 3.Circumfrential membrane force from radial...

Thaks RCHandy and Vesselfab, I have reviewed UG-82 (ASME VIII Div.1, 2008 Ed) and with regards to 100 % radiographic requirement on the area crossed. Is it the part of the code or G.E.P.? The reason for me to ask is the way tubesheet goes around shell. I have also attached the figure for...

I am designing a heat exchanger (nuclear) where I have tubesheet circulating around the shell. Tube sheet is connected to shell using filet weld. Part of the fillet weld also passes from through the longitudinal seam creating weld on weld situaition. Vessel is designed to ASME VIII Div.1 and...

Hi All, Can anyone advice me on the minimum size of I-beam or Universal beam required to lift 50 ton of weight. Material- BSEN10025 S275JR and length of 1500 mm.Hence the load comes to around 151 Kg/mm with the safety factor of 5. Any advice greatly appreciated.

Thanks guys-Your views are really helpful. Yes I am designing as per ASME and cast analysis of the material is dual certified to ASME 182 F316L/ F316. Just a hypothetical question- If the material was ordered in large amount and not dual certified,(i.e. only stated 316L) A)Can I show them...

Material SA 182 F 316L Pressure temperature rating -2.2-3 (ASME B16.5 –Refrence) Design temperature- 80 Design Pressure - 16 bar As per ASME B16.5 Flange rating I cannot use class 150 as my pressure is above by 1 bar and if I use class 300 it is costly and has got very high rating than...

Thanks Guys, I really appreaciate ur help. It helped me to make descicion congfidentalaly.

Dear All I am design ASME U stamp vessel. I wanted if weld on weld is premitted in ASME, i.e. longitudinal seam is run over by reinforcing pad weld. Ideally I am trying to do 100% radiography before aand aafter weld. I cannot find in ASME code if it is allowed? Any views greatly appreciated.

can I show fillet weld on the imported solid edge model ? I am using ansys workbench 10. I know I can show spot weld in simulation part but fillet ?? --------------------------------------------------------- Below is the summary of my steps 1) I have design the model in 'Solid edge' showing...

Dear Frnds, Please can someone tell me as how can I show the weld detail on ansys example:- Nozzle is welded to pressure vessel. Please can someone show me as how can I show on ansys.

Looks like no one know the reply. :-(

How do I transfer AutoCAD 2008 drwgs to Ansys ?

I do not understand, stainless steel is the design requirement plus having F316L provides more strength and corrosion allowance. Which material are you conmparing F316L against. please elaborate. My query was Will I need to recheck flange to Appendix 2 (ASME) as I am machining the flange for...

Thank you ALL Flange material will be SA182F 316L (because the design requirement is stainless steel) and there is a good website from where I got the information on flanges. http://www.texasflange.com/Dimensioncutsheet.htm I totally agree with your point guys and from my understanding on...

Thanks vesselfab on your guidance, Here is the complete information 406.4 mm (16") is the inside diameter of the shell and the wallthickness is 10 mm. Design conditon and flange rating MAWP = 10 bar @ 150 (degree) celcius Flange material = 2.2 austic stainless steel (316L) Flange rating 150 lb...

I have designed a shell of 406.4 mm and there is no weld neck flange having nominal bore of that dimension. The closest I can find is flange dimension if nominal bore 387.4 mm, I donot want to machine the flange as it will reduce the strength. Please advice me as to machine the entire flange...
