To reduce the installation space, it is necessary to optimize and improve the pipes of the detachable plate heat exchanger. The design of the detachable plate heat exchanger adopts stud connection or flange connection. The flange connection needs to extend part of the length of the detachable plate heat exchanger to ensure that the connecting bolts can be installed and removed on both sides of the flange. Therefore, the use of flange connection will increase the volume of the detachable plate heat exchanger. The stud connection requires an alloy-lined pipe. The alloy lining is in direct contact with the medium of the detachable plate heat exchanger, and the minimum thickness of the lining should not be less than the thickness of the plate. When using stud connection, the alloy lining generally uses TI metal material to meet the strong corrosiveness of the medium, which is costly.
