How to install a shell and tube heat exchanger?
1) The shell and tube heat exchanger should be 1.5 times the maximum working pressure hydrostatic test, the steam part should not be less than the supply steam pressure plus 0.3MPa; hot water part should not be less than 0.4MPa. Under the test pressure, the pressure will not drop for 10min.
2) The space between the front of the shell and tube heat exchanger should be left with a tube bundle, that is, the distance between its head and the wall or roof should not be less than the length of the heat exchanger. The net width of the equipment operation and operation channel should not be less than 0.8m.
3) All kinds of valves and instruments should be easy to operate and observe.
4) The vertical clearance between the highest point of the upper part of the heater (usually safety valve) and the lowest point of the building structure shall meet the requirements for installation and testing and shall not be less than 0.2m.
