Is this heat exchanger a pressure vessel?
Thread Content
The tube side of the heat exchanger operates at -0.09 Mpa and 250°C, with C9 solvent as the working fluid; the shell side operates at 0.4 Mpa and 300°C, with steam as the working fluid. Could you please help determine whether this heat exchanger constitutes a pressure vessel?
Under these parameters, if the volume of the shell side of this heat exchanger is greater than 0.03 m3 and its diameter is 150 mm or more, it is considered a pressure vessel and is subject to regulation by **the relevant authorities**
If the maximum cross-sectional area is greater than 150, it is considered a pressure vessel; whether it falls into a certain category depends on whether the volume of the shell side is greater than 0.03 cubic meters
Generally speaking, it is necessary to check against the list of special equipment. Check if there is a TS or CS mark in the upper right corner of the nameplate.
If the conditions are not complete, it is possible to make a distinction by referring to the definition in the tolerance specifications
