High Pressure Water Cooling Evaporative
Condenser Heat Exchanger
Heat exchanger tube plate selection is more complex. The tube sheet is an important compression
element that separates the pipe from the shell process fluid and is fixed to the heat transfer tube.
It is the most demanding operating conditions, it is subject to the tube and the shell side of any one of the
highest pressure and maximum temperature, so its timber is generally not less than the pipe and shell
side of the higher side of the timber.
For example: a heat exchanger tube selection of the substrate 2.25Cr-1Mo steel, shell selection of
1.25Cr-0.5Mo steel, then its tube plate substrate should not be less than 2.25Cr-1Mo steel.
In addition to the choice of tube sheet substrate, the tube board on the coating is also very important.
Because the tube board to be processed many heat exchanger hole.
And the individual defects in the composite steel sheet for the tube sheet will be enlarged or unable to be
repaired by the pipe hole machining. Therefore, the corrosion on the tube board is generally in the form
of surfacing, surfacing layer is generally double-layer, that is, the transition layer (E309L type) and the
surface (E347 type).
