 First, the scope
This series is suitable for petroleum, chemical carbon steel, low alloy and stainless steel floating head heat exchanger, condenser, also applies to other industrial sectors like the heat exchanger and condenser.
Second, characteristics
Floating head heat exchanger one end of the tube sheet fixed between the shell and tube box, the other end of tube plate can move freely within the shell, this feature can be seen at the scene. The heat exchanger shell and tube bundle thermal expansion is free, bundles can be taken out for easy cleaning between tube and tube. Floating head heat exchanger for high temperature, high pressure, large temperature difference between the shell and tube bundle and shell condition of the media easy to scale.
Third, the basic parameters of devices
1, heat exchanger, nominal pressure: 1.0 ~ 6.4MPa;
2, condenser Nominal pressure: 1.0 ~ 4.0MPa;
3, the design temperature: heat exchanger, condenser design temperature is 200 ℃. Buck used to allow heating at different temperatures to allow the maximum working pressure listed in Table;
