All Requirements for a Pressure Vessel Under ASME Sec 8 Div I

Perhaps you should design a pressure vessel for this class and a specific use and see if you run into any snags...You seem to be trying to skip the actual process of learning by doing part of education...

Also, it would be uncommon for a vessel to be designed and proceed into construction without a second person "sanity" check on the design drawings and calculations. Engage the help of a Mentor at the facility who can advise and guide, and provide the sanity check. Any errors in the design will be flushed out at this stage.

Also, it would be uncommon for a vessel to be designed and constructed without reference to the organisation's current standard procedures and design history. A review here of previous vessels built will flush out any errors in the design of the current one at this stage.

Also, the design will need to be checked by the Engineer/Surveyor from the company that is to provide burst/collapse indemnity insurance cover on the equipment. Any errors in the design will be flushed out at this stage.

Also, the vessel will need its final hydraulic test to be witnessed by the Engineer/Surveyor as above. Any errors in the design will be flushed out at this stage.

So it's a long way from going BANG just yet.

hi ,

thanks alot for all your replies.

@MJcronin : I do respect all of you certainly!! Although your post is quite helpful, however its quite angry towards its end I guess ..

I do understand its a big subject, and I didn't come here to get 2 replies and become an ASME Engineer out of that.

the intention is to understand those design calculations reports of existing vessels in a refinery , try some of that manually to get an idea how the thickness is found against Asme sec 8 div 1.

so far I was able to understand that you get a thickness required for internal pressure for heads and shell (and necks of nozzles), then check against external pressure as well.

calculate wind and seismic loads,

but I do have an issue understanding combinations of those in those calculations.. so I was seeking something like steps wise what to be checked to say the thickness found is good to go..

thnx

<...to understand those design calculations reports of existing vessels in a refinery...>

The underlying principles and standards for those will be found referenced in the documents themselves otherwise the documents are no better than toilet roll.

However, no design report is going to give the full picture, because as any vessel ages it will erode and corrode away slightly. So the additional documentation needed is the periodic inspection reports carried out by the equipment's insurers in support of burst/collapse/business-loss indemnity insurance cover on the equipment. There should be a file containing these somewhere on the premises and in the UK it is known as the General Register. Ask the Maintenance Manager at the facility to read a copy of it.

Thanks for all the help
