Among the two tube sheets at both ends, only one end is fixed to the shell, while the other end can move freely relative to the shell, which is defined as the floating head. The floating head consists of a floating tube sheet, a backing ring and a floating head cover, featuring a detachable connection structure that allows the tube bundle to be pulled out from the shell. The thermal deformation of the tube bundle and the shell are not restricted by each other, so no thermal stress will be generated. Its advantages include easy cleaning of both the tube side and shell side, and zero thermal stress buildup.
It is suitable for working conditions with a large temperature difference between the shell and tube bundle, or where the shell-side medium is prone to scaling.
