Floating Head Heat Exchanger, Carbon Steel Seamless Tube ASTM A179 , and Tubesheet ASTM A266 Gr.2N
One end of the tube plate at each end of the floating head heat exchanger is fixedly connected to the shell by a flange, called the fixed end. The other end tube sheet is not connected to the shell, but can slide relative to the shell, this end is called floating head end. Since the floating head is located inside the shell, it is also called an internal floating head heat exchanger.

Hydraulic Test
Specific steps are: remove the tube box outer head cover floating
head cover → replace the equipment gasket → installation of
floating head cover tube box → open the shell side opening flange →
from the side of the tube box water injection for the pipe
hydrostatic test → qualified after the installation of the outer
head cover → open the side of the tube box opening flange → from
the side of the shell process of water injection for the Shell
hydraulic test.
Test pressure are observed pressure gauge pressure drop, the flange
sealing surface and the corresponding equipment opening flange
leakage phenomenon, no leakage and no abnormal deformation is
qualified.
