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...
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.
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...
Hello Everyone
Attach file has case for two nozzle's reinforcement area overlap which is shown by dotted lines.
Can i consider reinforcement limit asymmetric as shown by thick red and blue line ???
ASME SEC VIII Div 1.
Thanks...
Hello Everyone.
Top dish opening has reinforcement area falling on shell, is it acceptable or does code says anything about it???
Does the radiography of top dish to shell comes in to picture???
Thanks.
Hello Everyone.
I want to know that how can i Auto change bolt size when i change hole diameter.
I attach two plate with bolted connection and i want inventor to auto select bolt size when i change hole dia in both two plate, is it possible???
thanks
Hello Everyone.
I want to know what is Dependent pressure chamber and Independent pressure chamber?
If anybody can explain or can give any reference..thanks in advance.
Hello Everyone
As per ASME sec.VIII div.1 Edition 2015 clause UCS-66(f) " Materials having a specified minimum yield strength greater than 65 ksi (450Mpa) shall be impact tested. However, they may be used at temperatures colder than minimum design metal temperature as limited in (1) and (2)...
Hello Everyone,
Is there any governing Thickness to consider full radiography when butt welding two different thickness together?? please find attached case where 36mm dishend(MOC SA 516 Gr 60) is butt welded(SF to Shell) to 32 mm shell(MOC SA 516 Gr 60). AS per table UCS-57 p.no 1 if the...
Hello Everyone.
My Vessel Jacket Design is as per attached file. and i am stuck at Longitudinal weld joint of jacket,as per ASME sec8 div1 Table UW-12 limitations is it not allowed??
As it is jacket shell longitudinal weld i can consider only Type 3 (single welded butt joint without use of...
Hello Everyone,
If Jacket O.D is 1000mm than as per Appendix:9-4(b) 100 mm opening is not acceptable??
i think i am missing something !!
please help
Thanks.
Hello Everyone,
I have vessel MDMT -60°C. with MOC SA-516 Gr 60.
As per PV Elite calculation it gives me excemption for Impact test with the help of UCS-68(c).
As per UCS-68(b) PWHT is mandatory but PV Elite still considering UCS-68(c) which i think is not-correct.
Here is the calculation...
Hello everyone,
My jacket design is as per figure9-6 (e-1)of appendix-9.now i am stuck at calculation for loadings by expansion differentials at design temperature.can i just straight calculate thermal stress and compare it with its material stress? or any other method????
Thanks
