Why choose equipment flanges for pressure vessels
Thread Content
RT: 1. Why are equipment flanges chosen for some storage tanks? 2. The heat exchanger must use equipment flanges, because of the tube sheet
I’m not sure what the original poster means; pipe flanges can be used, as well as other sealing devices
Depending on the requirements, heat exchanger tube sheets can also be available without a flange structure.
Whether it is a storage tank or a heat exchanger, equipment flanges are chosen for the purpose of disassembly, either to replace the tube bundle, for maintenance and repair, or due to transportation requirements.
The device flange is chosen mainly for ease of maintenance...
For a certain tower with dimensions of φ600×14800×12, there are three sections of packing inside the cylinder; it’s even impossible to install manholes. In such cases, the cylinder has to be split open and container flanges used instead
Pipe flanges are designed based on the dimensions of steel pipes. Equipment flanges are designed according to the dimensions of the equipment flanges. Therefore, the pipe flanges are aligned according to the standard outer diameter of the pipe fittings. The equipment flanges are aligned with the integer inner diameter of the equipment. If you use a steel pipe for the heat exchanger. Pipe flanges for the flanges can also be used.
