Flange connection requirements for high-pressure tower equipment
Thread Content
For a packing tower with a pressure of 6.4MPA, a diameter of 600MM, and a height of 20M, transportation constraints require it to be divided into two sections connected by flanges; no framework is considered in this design. What issues need to be taken into account?
With a design pressure of 6.4 MPa, it is difficult to choose the appropriate flanges for the equipment. Secondly, if the flange is positioned too low, the calculated pressure on the flange may be very high; I once did some calculations and found that the calculated pressure on the flange was around twice the design pressure. It is recommended to avoid using flanges as much as possible and carry out on-site welding. But with your tower of such a small diameter, how are the internal components installed?
Use PV to calculate the non-standard flanges; since it’s a packed tower, it’s normal to use flange connections. First select based on standard pressure vessels, and then adjust the dimensions
Flange connections are rarely used in towers, and the tower you’re referring to isn’t in a situation of excessive load or stress. It is recommended to use a crowbar to complete it!
