I would like to ask the experts: what is an appropriate spacing for the supports of a DN2600 liquid ammonia storage tank? I looked for some standards but couldn’t find what I was looking for. Are there any standards you can recommend? Thank you all
It depends on the length of your storage tank. If the tank is 6600 mm long, it should be 5380 mm; if it’s 8400 mm long, it should be 7180 mm. HG/T3154-2004: Horizontal oval-headed storage tank series
The length of the storage tank is 3600; is this based on approximately 0.8 times the length of the cylinder?
The distance from the circumferential weld of the cylinder to the centerline of the saddle can generally be taken as 1/4 of the cylinder diameter.
Refer to NB/T 47001 standard, 6900
Thank you for your reply; it was very helpful to me. Could you share information on the HG/T3154-2004 series of horizontal oval-headed storage tanks? I couldn’t find this version online
The files on the company computers are encrypted, so you won’t be able to view them even if they’re sent to you. I’m sorry about that
It’s okay, I’ll look again. Thank you for your concern anyway
Generally, for the circumferential weld of the cylinder to the centerline of the saddle, 1/4 of the cylinder diameter can be taken. Then, computational software is used for strength verification.
You can also take a look at NB/T47041-2014 and NB/T47042-2014; for these two standards, consider that I am dealing with containers, specifically tower-type containers
The standards for horizontal vessels specify that the distance between the saddles and the reference line of the head must remain within a certain range, so that the head can serve as a reinforcing element. Of course, if constraints require that the saddle be placed in the middle, that’s also acceptable as long as the calculations confirm it is feasible.
