Hello, i work in Romania and i design pressure vessels for the EU market. I never had to certify platforms and ladders for columns or pressure vessels ( both horizontal and vertical ) . These are seen as accessories for operating and maintaining the pressure vessel . I take into consideration...

Hello, you could have a look at Bentley Vessel.

Thank you all for your answers . A clarification is in order here : this is the path of the gases : fuel gas engine - flexible connection - housing of the flame arrestor - pipe ( this is the pipe in question ) between the housing of the flame arrestor and an heat exchanger that cools the gasses...

Hello all, i have a question for the members of this forum : we have on site a fuel gas engine who's exhaust gas temperature is around 600 degrees Celsius . These gases pass at atmospheric pressure throw a carbon pipe ( SA-106 Gr.B ) before being cooled .As per ASME B31.3 creep range for this...

Hello kingnero , just a heads up about rolling a sheet of metal in many,many passes. In our workshop we tried at one point to roll a 40 something mm sheet of plate on a machine that was strong enough to roll a 24 mm sheet in 2 passes . We also thought to roll it in many passes. The problem we...

Good evening everyone. I have the next situation : a underground double wall pressure vessel is about 1 meter close to a a column foundation which is located north of the vessel . On the est and south there is a road at about 2 meters on which there will be a crane installing some equipment of...

Be carefull, PD 5500 was withdrawn from the list of British Standards because it was not harmonized with the Europeran Pressure Equipment Directive PED (97/23/EC) , former PED 2014/68/EU. I don't know if in the latest revisions they made that harmonization. And i didn't ask you if your vessel...

r6155, i know that it is not required that a manhole of DN600 be put on every vessel. I have designed vessels with manholes , handholes and even headholes 😀 . My point is that there should be some sort of inspection opening. At some point in time you need to inspect the inside of the vessel...

it is your decision. But you said you have internals ( baffles and coils ) . All the vessels that i have designed have a manhole or, if a manhole can't be installed , have a body flange with a removable blind flange. Something like this : There will come a time when you will need acess to those...

Usually , for every vessel there is a manhole , about DN 600 . You need it in case something happens to the internals . Some more questions : - what design code are you using ( in EU there is 13445-3 and it is harmonized with PED 2014/68/EU ) - what is your design temperature ? - what materials...

OK. Considering that England is still in the European Union you should read PED 2014/68/UE. Oh,and by " loads acting on the process nozzles " you should read WRC 537 and WRC 297 . It has nothing to do with " equal area method to account for the nozzles/flanges ".

Where will this vessel be installed ? Is it the EU (Europe ) ?

Hello, you can't just take some dimensions for legs from a book and expect it to work. You also need to provide a understandable design calculation in which you need to take into account earthquake , wind and other forces that impact your vessel. Have you designed the rest of the vessel ? is...
