Every tank needs to be equipped with a vent and a drain, right? How should the location of the vent and the drain port be determined?
It’s not always the case; it depends on the process requirements. For example, if there is a pipe opening that can serve as an inspection hole, then it may not be necessary to provide a separate inspection hole. Similarly, if a pipe opening is used for drainage or venting, then an additional inspection hole might also not be needed. I’ve seen devices with as few as two pipe openings – just an inlet and an outlet – and it’s the structure and process requirements that determine this
There is a sewage outlet, so that even if the inside gets dirty, the wastewater after cleaning can be discharged thoroughly and cleanly.
It can be said that each tank has the function of emptying and draining waste, but it isn’t necessary for there to be a separate opening for this purpose, as other pipe connections can also serve this function. For example, the liquid outlet/inlet at the bottom, and the liquid inlet/outlet at the top

It’s not required in terms of manufacturing processes, but during maintenance, pressure needs to be applied. Don’t you need to fill it with water? After applying the pressure, shouldn’t the water be drained? It should be drained through the drain outlet. These are the basic requirements for chemical processing equipment ； Some people on the forum said that the process pipe openings could be used, but upon careful consideration, during maintenance in the factory, it’s necessary to install blind flanges and also empty and replace the fluid – so this approach is actually not feasible ；
Not necessarily; if there are other process ports that can serve for venting and drainage, it may not be necessary to provide separate venting and drainage ports.
There must be an opening at the highest point of the device, and one at the lowest point. The heat exchanger standards have been established. But for containers, I’ve also been looking for standard regulatory provisions, and I haven’t found any yet.
It depends on the salary; it’s not certain. For the jacketed container I designed recently, users don’t need to empty it, only to drain waste from it.
