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.

Heat exchanger unit comprehensive corrosion control is from the design, manufacturing, storage, transportation and installation, operation and operation, maintenance, and other five aspects of corrosion protection control, so as to reduce corrosion losses to a minimum level.

The refrigeration system with Freon as the refrigerant medium mainly consists of 4 major components, namely compressor, condenser, expansion valve, and evaporator. Condenser and evaporator in function, are different temperature fluid mediums to achieve mutual heat exchange equipment, so collectively referred to as heat exchangers. In the rail vehicle air conditioning industry, the more finned tube heat exchanger is used.

Finned tube heat exchanger is usually composed of a whole heat exchanger group by the partition, fins, seal, and guide piece, mainly heat is distributed to the air through the fin tube, and the equipment plays a role in controlling the temperature when the equipment temperature can not be effectively reduced to consider the finned tube heat exchanger problems.

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.

The finned tube heat exchanger is one of the most successful inventions in the process of improving tube heat exchange, and this method is one of the most widely used in various tube heat exchange enhanced heat transfer methods. It is widely used in various industries such as dehumidification, drying, heating, and ventilation systems for air heating or cooling air conditioning systems for air cooling, power, petroleum, and chemical industry.

Corrosion of heat exchanger units​ is a common phenomenon. The phenomenon and mechanism of metal corrosion are more complex, and the scope involved is very wide. According to the reaction mechanism, metal corrosion can be divided into two categories of chemical corrosion and electrochemical corrosion. According to the appearance of corrosion characteristics, metal corrosion can be divided into two categories of comprehensive corrosion and local corrosion. Below we introduce several common corrosion phenomena of heat exchanger units.

With the widespread use of heat exchangers, ordinary people are coming into contact with more and more heat exchangers. It is also important to acquire some knowledge about heat exchangers and to learn how to install them. Here we take the displacement heat exchanger as an example and explain its pe

The finned tube heat exchanger is an industrial heat exchange equipment for hot water or steam, which expands the heat exchange area by adding fins to the glossy base tube. Its structure is a joint unit consisting of a porous plate frame and a steel heat sink row tube, which is suitable for air heating, cooling, and waste heat recovery in large and medium-sized heat exchange systems.

The displacement heat exchanger is a very widely used heat exchanger, which is mainly composed of the body, steam coil assembly, steam import and export, hot and cold water import and export, etc., so how to choose a displacement heat exchanger, today to introduce you to the volumetric heat exchange
