Why is there no reinforcement ring at the heat exchanger tube box interface?
Thread Content
Is it because the tube box is relatively thick?
This requires calculations for reinforcement through openings; if the effective reinforcement area is large, there is no need to add reinforcement rings
If the reinforcement calculation for the opening after takeover is approved, there is no need to install a reinforcement ring.
The series of floating-head heat exchangers have relatively thick tube boxes, so no reinforcement is required.
Since the tube box stubs are relatively short and do not provide sufficient effective reinforcement area, the tube box is usually reinforced as a whole
Whether reinforcement rings are needed depends on calculations for reinforcement after making the opening; if the thickness of the tube box shell is sufficient, no reinforcement rings are required for the opening.
The cylinder and nozzles are relatively thick; if the calculations show it’s sufficient, there’s no need to add reinforcing rings
