Semi-tube jacket pitch
Thread Content
How is the half-tube pitch determined for half-tube jacketed equipment? How is the heat exchange area calculated? Thank you!
Can the pitch be designed at 1.25 times the outer diameter of the half-tube? For example, DN20: 25*1.25=32; DN80: 89*1.25=110
Please refer to the attachment for information; these are the data commonly used by our company
The pitch of the half-tube jacket is usually determined based on the diameter of the equipment, the heat exchange requirements, and the flow rate of the fluid. Generally, the pitch should be such that there is sufficient space between the half-tubes for adequate heat exchange, while also ensuring the compactness of the structure. The calculation of the heat exchange area can be carried out using the following formula: \ Where: – \( A \) is the heat exchange area ； - \(n) is the number of half-tubes ； - \(d) is the diameter of the half-tube ； - \(L) is the length of the half-tube. Please adjust the parameters according to the specific situation to meet your particular needs. .
