A question regarding the installation of the hot oil pipeline at the bottom of the tower

I believe that the pipelines passing through the skirt of a small tower do not need support; since the tower is small, the diameter of the corresponding pipelines is also small, so no support is necessary. For large towers, I usually install three support plates; these plates are welded to the pipelines and also pass through the rings in the skirt. A gap of around 3 mm is left between the support plates and these rings, as the vertical distance of the pipelines extending from the bottom of the tower isn’t very large, and 3 mm of clearance is sufficient. I don’t dare to say anything about how the pipes further out are supported; I’m only responsible for designing the containers, not the pipes. I have designed few tower systems; please feel free to point out any mistakes.

I believe that as long as the distance between the pipe outlet and the spring bracket meets the requirements for the pipe span, there is no need to install supports when the pipe passes through the tower base. This allows the pipeline in front of the support to maintain a certain degree of flexibility. This was something that the instructor mentioned during the stress analysis training session I attended last time; he used as an example the piping at the side outlets at the bottom of large storage tanks. The first option is to use spring supports like those shown in your picture, with a certain distance maintained from the outlet to ensure flexibility, while the second option involves using flexible metal hoses at the connection points of the outlets. The explanation given at the time was that the foundation at the bottom of large storage tanks would experience some settlement. Also, am I showing off my skills in front of an expert, haha

No, thank you for sharing. These are the detailed aspects of the design that I haven’t quite understood yet; if these details aren’t handled properly, it can lead to various problems during the production of the device. Metal flexible hoses are generally not used at the bottom of the tower, as settlement needs to be taken into account. Metal flexible hoses are more commonly used for the inlet and outlet pipes of storage tanks

I really like such professional answers; it’s great to see people who are eager to help. More people are welcome to join in the discussions. I also saw this title and thought of the triangular support you mentioned; I didn’t understand it, which is why I have this question.

Metal hoses pose a risk of leakage; different storage tanks and different media have specific requirements, and some applications do not allow the use of hoses
