Is it good to have direct piping connections between the tower and the reboiler at the bottom of the tower?
Thread Content
As the title suggests, it’s a vertical tower with a reboiler at its base; the equipment flanges are connected directly to each other, without any pipes in between. Is this a good approach? Are there any standards that address this issue?
It depends on how long the tubes built into the reboiler are; some models come with long tubes, which is fine. It would be best if the original poster could send some pictures for reference.
This is generally not done; firstly, it is inconvenient for operation and maintenance, and secondly, thermal expansion means that stresses cannot be eliminated, unless the material, wall thickness, and degree of expansion are all the same.
Look, the specifications clearly state that, provided the thermal stress requirements are met, direct connections should be used as much as possible; it says it’s not appropriate to use anything other than direct connections, and there are many cases of direct connections in practice, you know
