Shell and tube heat exchanger
1. Features&Performance
1.adopting superior external thread copper tube to ensure high heat exchange efficiency,compact volume and light weight.
2.gas tightness testing under air pressure 2.4Pa before delivery to ensure quality.
3.equiped with safe fusible plug to ensure safe through automatical melt and depressurization when liquid reach specific temperature in shell.
4.condenser end cap equiped water discharge device to avoid tube damage caused by water into ice at cold weather.
2. Usage & Applications
The shell and tube exchanger is a kind of heat exchanger that widely applied for chemical and alcohol production. It is mainly composed of the shell, tube sheet, heat exchanging tube, sealing head, baffle plate, ect. It can be made of or dinary carbon steel, red copper or stainless steel. During the heat exchanger, a king of fluid enters from the tube connection of the sealing head, flows in the tube and exits from the other tube connection of the shell and exits from the other tube connection of the shell, which is called shell pass.
