In case anyone is experiencing the same problem, Factor B has a unit of MPa. (Strangely the chart that I was referring to is missing a unit). Pa = 0.25 [MPa]. -> 36 psi

@SnTMan, There will be openings... I did not worry too much about the openings at this point, as there will be a port (NPT, Tri-clamp, etc) which would enforce it. @goutam_freelance, I followed section VIII - Div 1. Got Factor A and B, and from that, I calculated Pa (allowable working...

@LittleInch, thank you. I've been contacting many vacuum receiver manufacture. Appreciated your feedback :)

This vacuum receiver tank is used as a vacuum reservoir. It will be constantly connected to a vacuum pump. This tank will be used to pull a vacuum from a smaller container rapidly. So, the ports to those smaller container will be open and close, which would cause the fluctuation of vacuum level.

I am looking for 304L or 316L stainless steel. This tank will be placed in a food processing facility. I was also considering steel tank with powder coating outside and epoxy lined inside to lower the budget too.

Thank you all for helping me out. @goutam_freelance I will definitely check out ASME Sec VIII Dev i claus for this. @EdStainless Would a tank rated for full vacuum withstand the cyclic loading then? Problem is that I would much prefer to buy a stainless steel tank; then the price would be 7~8...

Thank you for all feedbacks. Cyclic loading is indeed a challenge. Custom making one will be quite expensive... so I was hoping to find an off-the-shelf item. This tank is never subject to a pressure higher than atm for its entire lifetime. This tank is subject to be under cyclic loading 5...

Thank you all for your feedbacks. Many ASME compressed air tank tells about its maximum pressure rating without min pressure rating. For example, McMaster Carr is selling an ASME code pressure tank, which does not talk much about its min pressure. I think there is no way that I con contact...

I am looking for a vacuum receiver tanks, and I could not find many. I read some online forums about ASME pressure tank code, and they do talk about external pressure stability. Can I use an ASME pressure tank as a vacuum receiver tank? The tank is subject to go through cyclic load of...

Thank you all for your answers to this post! Much appreciated!! :)

Hellow all, I been tasked to add lifting eyes to an existing machine and to do a structual analysis of lifted machinery when it is lifted. The machine will be lifted using a forklift/crane and hoist to a flat-bed truck for transferring. I been researching regulations, and all I could possibly...
