Urgent help needed! ! Regarding heat exchangers
Thread Content
Gentlemen, I’m a newcomer and have an urgent question that needs answering: What are the requirements for insulation in different types of heat exchangers? ? Additionally, on some drawings, insulation material is used on the tube side; so is the insulated part of the tube side the internal heat exchange tubes? ? Thank you so much!

Is there anyone expert in this area who can help? I, a humble woman, would like to express my gratitude`~~
The requirement on the drawing for insulation on the tube side means that the outer walls of the end caps (including the tube boxes) need to be insulated. If heat insulation is required for the shell side, it refers to the outer wall of the shell outside the tubes.
Thank you so much, sir! With your help, everything became clear to me~~ Many thanks! You’ve really helped this girl out a lot~~~:)
May I ask again whether the sliding saddles at both ends of the heat exchanger serve the same purpose as the end caps?~~~
Also, does the tube sheet section need to be insulated?~~~
What is meant by heat preservation and insulation refers to the insulating treatments applied to the outer walls of the equipment. Insulation for the pipe side refers to the pipe box area, while insulation for the shell side refers to the intermediate cylinder section. Additionally, sliding saddles are used to provide enough clearance for thermal expansion of the heat exchanger; however, I’m not sure what you mean by the function of the end caps
Thank you very much. Then, how is the heat insulation capacity of the tube side calculated? Is there any standard formula for that? In the drawings I’ve seen, the tube side consists of a section of tube box along with sliding saddles. Can we calculate it using the formula for end caps plus the formula for the equipment cylinder? Thank you!`~~~
The thickness of the insulation layer is generally determined through heat transfer calculations carried out by the process engineering team; there are specialized calculation software tools available. For equipment-related calculations, it is sufficient to comply with the requirements specified in the process data sheet. The strength of the equipment is calculated using the SW6 calculation software.
