Floated type shell&tube heat exchanger is mostly used for large temperature fluctuations and temperature differences, compared with Fixed Tube Heat Exchanger, its structure is more complex and more expensive.
One end of the tube is fixed on an immobile Tube Sheet, which is clamped between the shell Flange and the tube flange, and is connected by bolts; the other end of the tube is fixed on a floating head tube sheet, which is clamped between the floating cover and the hook ring connected by studs, forming a floating head that can move freely in the shell.
If the tube bundle and the shell are heated and elongated, they do not affect each other, so there is no temperature difference stress. The floating part is a detachable connection consisting of the floating tube sheet, hook ring and floating cover. It is easier to take the tube bundle out, and the tube can be cleaned both inside and outside and is easy access.
