What are the corners that appear on the heat exchanger shell?
Thread Content
Experts, could you please analyze what these edges and corners on the heat exchanger shell are? Are they related to the baffle plates, and what causes them?
The corners that appear on the heat exchanger shell may be caused by internal components such as baffle plates. The function of baffle plates is usually to change the direction of fluid flow and increase the velocity of the fluid as it passes through the heat exchange surface, thereby improving the efficiency of heat exchange. This structural design results in the cylinder having angular features in its appearance. Furthermore, the reasons for this situation may also be related to welding, assembly, or material selection. Generally, it is necessary to analyze the specific reasons based on the particular design and usage conditions. .
Honestly, I really didn’t notice something like this. Is there any good way to handle heat-induced salt instability in the amine solution used for solvent regeneration? https://bbs.hcbbs.com/thread-5668900-1-1.html (Source: Haichuan Chemical Industry Forum)
The outer diameter of the baffle must be smaller than the inner diameter of the cylinder; otherwise, it cannot fit inside. Therefore, such corners have nothing to do with the baffle. Is the cylinder made of steel pipe? If it is a steel pipe, the sharp edges may be caused by the processing of the steel pipe.
Is it possible that the wall thickness of the cylinder has thinned? Traces of support plates and baffle plates. Is there negative pressure under the equipment, or does people often stand on it?
This kind of issue should not occur in the welding of cylinders made from rolled sheet metal
It’s possible, but why corners and not bulges?
