For 3" Pipe for first case required thk is 10mm for second case required thk is 22mm

Hello Everyone, Why thickness required due to external pressure for shell on which limpet coil welded has vast difference between two different cross section 1) Half circular 2) Box type as in App.9 ,Fig 9-5 (f-1). In first case where Half coil limpet is considered gives very less required...

Dear Experts, I want to know what deformation will be on tank when its heated to 600 °C temperature and air cooled after that. I am using Nastran In-CAD. I modelled the tank (Carbon steel)and it gave me deformation at 600°C but than problem is how can i save the deformed geometry of the tank and...

Hello Everyone, Please have a look to attach file for a Plate from which a small piece is formed in a way where it bends from the plate thickness in third direction. In pressure vessel construction as per SEC VIII div.1 any bend restricted to longitudinal or transverse direction of rolling...

Oh Yes, My mistake. Sorry PREX

Have a look this attached file.http://files.engineering.com/getfile.aspx?folder=85ded17e-5208-4c74-8e08-b07bb2b8bff9&file=kkk.jpg

As there is no external pressure consider App 1-4(d).

Hello Everyone. I want to know about how to do design for Glass tube working under pressure both inside and outside. And how can i do certification (...Like U-Stamp)...means which code,directive or certification it require. Size of DN 200 and 10 Bar pressure for Borosilicate Material. Thanks.

IRstuff thanks a lot. Yes, you can do absolutely anything and you are the expert..

Hello Everyone Thank you Occupant,IRstuff,Monkeydog for your help. As in the given solution by Occupant do i have to manually select the value of "D" or i can make it automatic? Thanks for your help.

It's not for school... I am still learning mathcad that's the reason.ni tried but don't know what to use exactly..

Hello Everyone, Please help me how can i get the value of "D" the equation is like 26=(4500+D^3)/ 45+3*(D^2 - 23). i am using Mathcad 15.0. Thanks.

Hello Everyone. Please suggest me any reference to design Leg Support welded on Bottom Dish. Thanks.

Thanks Mike and racookpe1978 for your reply. Please look attached file for detail information.That is for 12 bar at 250°C for 1.5 Sp.gravity fluid and follows ASME sec8 Div 1. http://files.engineering.com/getfile.aspx?folder=3ab83f33-bb61-41b1-8841-e413ee9d9c51&file=a.docx

Hello Everyone. I want to know about how to do calculation for Large opening (opening exceeds one-half of head diameter) on flat cover (Blind flange as Fig UG-34 (j)), as app-14 is only for integral flat head and UG-39(c) doesn't say about it. Should i go as per UG-34 for thickness...

Thank Metengr for your explanation. Does it still require to follow stress relieving temperature(for post forming heat treatment of seamless head)as per Table UCS-56-1 to UCS-56-11 for post WELD heat treatment requirements. Thanks.

My case is of two opening on F&D head.

Thank TGS4 but with all Respect please have a look attached interpretation. http://files.engineering.com/getfile.aspx?folder=41dec46a-c924-4b45-b912-fdde12dfce93&file=Int..docx

Thanks Mike. Thanks prex, with all respect But 50% of the summed requirement for reinforcement is for Fig.UG-42.2(b) where three nozzle's reinforcement overlap. For two nozzle's reinforcement area overlap in UG-42(a) says combined reinforcement that has an area not less than the sum of area...
