Heat exchanger tube sheet
Thread Content
Dear experts, could you please tell me what the purpose of the groove on local view I on the tube sheet is? Thank you~
It’s best to have a master diagram. Because these devices vary, it is difficult to determine their location only based on partial features. When raising an issue, the more information available, the more comprehensive and detailed it is, and the more helpful it is for solving the problem. For reference.
It may be a structure that reduces local stress at the weld joint of the cylinder
Facilitates full penetration welding, enables seamless patching, and helps with the release of welding stresses{:9001:}
First, it reduces stress concentration; second, it facilitates full penetration; third, this structure can meet the requirements of ultrasonic testing
You are very professional; I would like to ask you for advice! Is this groove on the side of the heat exchanger tube sheet that is close to the shell side? It’s not clear which weld is being welded for convenience: handshake
For further clarification, it is one of the connection structures between the tube sheet and the tube box or shell as specified in Appendix I of the GB151 heat exchanger standard. Select according to the design requirements.
