Tube sheet calculation
Thread Content
The SW6 software provides two options for calculating tube sheets: one is based on GB/151 standards, and the other is based on JB4732 standards. If the calculation using GB151 standards does not yield a successful result, but the calculation using JB4732 standards does, is it feasible to design the tube sheet using the methods specified in GB151?
The use of local stress analysis is permitted
Actually, using 4732 for the calculation is more reliable than using GB151. The prerequisites for calculating tube sheets in GB151 are too strict. It is required that the pipes be arranged evenly and have consistent diameters, etc.
There should be no problem, but be sure to check whether JB4732 has any special requirements regarding manufacturing...
There is an example: if calculated according to GB151, the thickness needs to be 100 mm, but if JB4732 is used, 50 mm is sufficient.
It is feasible; 4.1.6 in GB/T151 refers to 4.1.6 in GB150.
It can be calculated locally as 4732.
It is certainly permissible to perform local calculations in accordance with JB4732; the tube sheet should be calculated based on the analysis and design standards. Are there any special requirements regarding its structure? For example, if the connection between the tube sheet and the tube box or shell is of type b as specified in GB151, are there any regulations regarding such connection structures?
I agree with you; the issue needs to be considered comprehensively, and it must meet the requirements specified in JB4732.
