Horizontal tank with jacket
Thread Content
In the company, 12-cubic-meter vertical tanks are used first; the lower part of these tanks has a jacket, and a refrigerant flows inside this jacket； Now I need to switch to a 20-cubic-meter horizontal tank with a jacket for the refrigerant. I would like to ask whether all horizontal tanks come with full jackets? How is feeding and discharging done in a horizontal tank with a jacket? Solve
Reference can be made to the insulation support systems used for insulated pipes. The supports are divided into upper and lower sections, with a PTFE material used as a separator in between; the upper section serves for insulation
A full jacket or a half jacket is selected as needed. All pipes can be welded to the inner layer of the equipment through the jacket layer; at the outer jacket, they can be directly welded to the passing pipes, or a hole slightly larger in diameter can be made to avoid the weld joint between the inner layer and the pipes, after which a short pipe is used to connect to the inner layer and sealed with a weld.
Whether it is a full jacket or a half jacket is determined by the process; if steam condensation is involved, steam enters from above and exits from below, while if no phase change occurs, steam enters from below and exits from above. Of course, this is still determined by the process.
Structurally, the manufacturing complexity of a fully jacketed horizontal tank is higher than that of a semi-jacketed one.
The horizontal tanks are available with full jackets as well as half jackets. In the cases we handled before, the half jacket was only applied to the barrel section; when using a half jacket, it is important to ensure proper support from the saddles, which need to be reinforced.
Answer #4 is pretty good. It’s just that the all-jacket design is relatively more complex and requires more consideration; it’s not acceptable if there are leaks at any of the pipe connections or saddles :)
Horizontal vessels with jackets are not within the scope of application of NBT47042； Those with prior experience can refer to the comparative design methods in GB150 ； It is not recommended to install the saddle on the jacket.
