The heat exchanger plate of welded plate heat exchanger is made of special stainless steel and pressed by a special mold. The surface is smooth and not easily scaled. Its unique corrugated design allows the fluid to produce turbulence even at low flow rates, resulting in high heat transfer efficiency.

The advantages and uses of different types of plate heat exchangers are different. So, do you know what are the advantages of welded plate heat exchangers? And, what are the daily maintenance precautions for heat exchangers? Here is a brief introduction to the relevant content.

​In actual use, fouling will gradually increase on the circulating water side of the heat exchanger, so the heat exchanger should be treated for fouling after a period of use. The formation of fouling has a lot to do with water quality. Water quality varies greatly from place to place, welded plate heat exchanger applications are different in the water quality requirements are not the same, so it is difficult to determine the minimum requirements of water quality.

Heat exchangers are widely used in various fields of industry and agriculture, and heat transfer equipment can be found everywhere in daily life, and is one of the indispensable process equipment.

As the application areas of heat exchangers become more and more widespread, the possibility of coming into contact with heat exchangers in our daily life has increased greatly. It is also very beneficial for us to know a little about heat exchangers.

Shell and tube heat exchangers​ are currently the most widely used type of heat transfer equipment. Compared with several other inter-wall heat exchangers, the unit volume of equipment can provide a much larger heat transfer area, and the heat transfer effect is also better. Due to the compact structure of the equipment, the solid, and can choose a variety of materials to manufacture, it is more adaptable, especially in large devices, and high-temperature, high pressure is widely used.

Shell and tube heat exchangers consist of a shell, heat transfer tube bundle, tube plate, tube box, and other components. The shell is mostly cylindrical, the internal tube bundle, tube bundle ends fixed in the tube plate. Heat transfer of hot and cold two kinds of fluid: one in the tube flow, called the tube process fluid; the other outside the tube flow, called the shell process fluid.

Shell and tube heat exchanger due to the difference in temperature of the fluid inside and outside the tube, because of which the shell of the heat exchanger and the temperature of the tube bundle is also different. If the difference between the two temperatures is large, the heat exchanger will generate a lot of thermal stress, resulting in the tube bending, fracture, or pulling off from the tube plate.

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.

Leaks occur when they cause a reduction in feedwater pressure and a reduction in the amount of feedwater sent to the boiler. Therefore, the discovery of shell and tube heat exchanger tube system leaks immediately stop the heat exchanger to reduce the number of damaged tubes and reduce the degree of
