The plate heat exchanger is a new type of high-efficiency heat exchanger made of metal sheets with certain corrugated shapes stacked on top of each other. A thin rectangular channel is formed between the various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-to-liquid and liquid-to-vapor heat exchange.

Heat exchangers, as common chemical equipment, also have many problems in the process of use. Take the shell and tube heat exchanger as an example, the leakage of the tube itself is a very serious problem. In the following, we will talk about the reasons why leaks occur and hopefully help with solutions later on.

Any corrosion problem must be investigated through the field, through the daily monitoring and regular testing of equipment, in order to understand the shape of corrosion and grasp the specific circumstances of corrosion, in order to take effective measures to solve it. Heat exchanger unit corrosion investigation can be in the heat exchanger unit shutdown maintenance to take the regular corrosion inspection. Here we introduce some inspection methods and prevention strategies.

A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers occupy an important position in chemical, petroleum, power, food, and many other industrial products. Its heat exchangers in chemical production can be used as heaters, coolers, condensers, evaporators, reboilers, etc. But how to choose a good heat exchanger becomes a problem. Here we will introduce how to choose a heat exchanger unit from different aspects.
