Here I will tell you the installation of floating heat exchanger.
Provide valves and bypasses in the piping system so that both the shell-side and the tube-side may be bypassed to permit isolation of the unit for inspection and repairs. Long radius elbows should be used in lieu of standard elbows wherever possible, because of their superior flow characteristics.
When not integral with the exchanger nozzles, thermometer well and pressure gauge connections should be provided in all piping to and from the unit, and located as close to the unit as possible. Vent valves should be provided so units can be purged to prevent vapor or gas binding. Special consideration must be given to discharge of hazardous or toxic fluids. Drain connections should not be piped to a common closed manifold.
In all installations, care should be taken to eliminate or minimize transmissions of fluid pulsations and mechanical vibrations of the heat exchanger. Quick-opening and closing valves controlling fluids to or from the heat exchanger may cause water or steam hammer, which can cause serious damage to the heat exchanger.
