Tube sheet, also known as plate and shell heat exchanger, is a common type of heat exchange equipment, which is composed of a number of parallel-arranged tubes alternating with corrugated plates. Inside the tube plate, fluids are exchanged between the plates and inside the tubes for cooling or heating purposes.
The Types of Tube Sheet
According to different forms and materials, the tube plate can be divided into a variety of types, the following are a few of the common ones:
1. U-shaped tube plate: its tube is U-shaped, and the tubes are connected by corrugated plates.
2. Fixed plate tube sheet: the tubes are fixed on the corrugated sheet by flanges.
3. Submerged tube sheet: the tubes are inserted into the corrugated sheet and riveted.
4. Spiral tube plate: its tube is spiral, strengthening the heat exchange effect of the tube plate.
The Use of the Tube Plate
Tube plate is suitable for many industries, such as metallurgy, chemical industry, petroleum, air conditioning and so on. Its main uses include: cooling, heating, evaporation, condensation, reboiling and gas exchange.
The Application of the Pipe Sheet
Tube plate is widely used in many fields because of its unique structure and function:
1. Chemical industry: In chemical production, heat exchanger is one of the indispensable equipment. As a key component of the heat exchanger, the tube plate undertakes the important tasks of support, fixation and heat transfer.
2. Petroleum industry: in the process of oil extraction and processing, a large number of heat exchangers need to be used for heat transfer and recovery. Tube plate with its excellent performance and reliability, has been widely used in the petroleum industry. 3.
3.Electric power industry: in electric power production, boilers and condensers and other equipment need to use the tube plate to support and fix the tubes, to ensure the normal operation of the equipment and efficient heat transfer.
4.Food and pharmaceutical industry: in the food and pharmaceutical industry, the purity and safety of the product has very high requirements. Sanitary double tube and plate heat exchanger ensures the quality and safety of the products with its unique structure and material selection.
5. Other industries: In addition, the tube plate is also widely used in pressure vessels, steam turbines, large central air conditioning and other industry sectors, providing a strong guarantee for the normal operation of various equipment and efficient heat transfer.
The Advantages and Disadvantages of the Tube Sheet
The advantages of tube plate are its high heat transfer efficiency, small footprint, compact structure, easy maintenance.
However, it also has the following shortcomings: due to the presence of many contact points within the tube plate, which can easily lead to cleaning and maintenance difficulties; in addition, the use of the tube plate needs to be cleaned and maintained, otherwise it is prone to scaling and fouling, which leads to a decline in the use of the effect.
Tube plate is a very commonly used heat transfer equipment, its variety, wide range of uses, in many industries and fields play an important role.
