How should this container be divided?
Thread Content
Low-temperature liquefied gas storage tank (double-wall with vacuum between), with a capacity of 500 L; the inner liner is used to hold liquid nitrogen. If a steel pipe is inserted through the inner container of the storage tank from one end to the other (with gas flowing inside it at a nominal pressure of 35 MPA), entering at one end and exiting at the other, then the pressure inside the steel pipe is independent of the pressure inside and outside the storage tank’s inner container (the storage tank is used solely as a cooling container to cool the gas flowing inside the steel pipe). How is this tank classified?
:Victory: Let me share my opinion. First, determine whether the piping running through the equipment is classified; of course, such piping is not very large (with an inner diameter of less than 150 mm), and it generally isn’t classified either. Excluding takeover, classification is based on the chamber that holds liquefied gas.
Thank you, the diameter isn’t very large, DN25
