Fixed Tube Heat Exchanger

Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall. Advantages: simple and compact structure, high pressure resistance
