What are the components of finned tube bundle?

The heat exchange unit composed of multiple finned tubes arranged according to certain rules is called finned tube bundle. A finned tube heat exchanger can be composed of one or more finned tube bundles. Understanding the finned tube bundles is helpful to the application of finned tube heat exchangers.

 
finned tube bundleWhat are the components of finned tube bundle?
 
1. Multiple finned tubes: basic elements of heat transfer;
 
2. Tube box header or tube plate: connect the box, elbow or steel plate at both ends of the finned tube. When the finned tube is connected with the box or tube plate, the spacing between the finned tubes is fixed, and the tube box makes the fluid in the tube form a continuous flow channel;
 
3. Frame: support and fix the whole finned tube bundle.
 
The finned tube bundle is the main part of the air cooler, which is composed of finned tubes, tube boxes and frames. It is an independent structural whole. Its basic parameters include the tube bundle type (usually horizontal type, inclined top type, etc.); Working pressure and temperature, fin tube type and specification; Type of tube box, length and width of tube bundle, number of tube rows, number of tube passes, etc.
 
Finned tubes are also called extended surface tubes, which can have shells or not. Finned tubes are processed with many fins on the original tube surface, both on the outer surface and the inner surface, so that the original surface can be expanded to form a unique heat transfer element.
 
Finned tubes are widely used in power, chemical, refrigeration and other industries. They are mainly used in air coolers, which can reduce industrial water shortage and environmental pollution of industrial water. In terms of heat transfer enhancement, low ribbed screw tubes and micro ribbed tubes are widely used for phase change heat transfer in evaporation and condensation.

ASTM A213 T22 extruded finned tube?

  What is ASTM A213 T22 extruded finned tube? ASTM A213 T22 extruded finned tube is a heat exchanger tube with extruded aluminum fins on the outside surface, made from T22 grade steel, which is an alloy steel per ASTM A213 standard. The fins are extruded from the base tube, which increases the surface area and enhances heat transfer efficiency. These finned tubes are typically used in high-temperature and high-pressure applications, such as boilers, superheaters, and heat exchangers in power plants or industrial settings. The T22 grade steel has good high-temperature strength and resistance to corrosion and oxidation. Why use ASTM A213 T22 extruded finned tube? ASTM A213 T22  extruded finned tubes  are used in applications where high-temperature and high-pressure resistance is required, such as in boilers and heat exchangers. The use of an extruded finned tube made of this material can improve the heat transfer rate by increasing the surface area of the tube, which enhanc...

What are carbon steel finned pipes?

What are carbon steel finned pipes? Carbon steel finned pipes are pipes that have fins attached to them, typically for the purpose of increasing the surface area of the pipe. The fins can be either integral or attached separately, and they are typically made from a different material than the pipe itself, such as aluminum or copper. The use of  carbon steel finned pipes  are common in applications where heat transfer is important, such as in heat exchangers, boilers, and air conditioning systems. By increasing the surface area of the pipe, the fins allow for more efficient transfer of heat between the fluid flowing through the pipe and the surrounding air or other fluid. Carbon steel is a popular material for finned pipes due to its high strength and durability, as well as its relatively low cost compared to other materials. However, carbon steel is also susceptible to corrosion, so it may not be the best choice for certain applications where corrosion resistance is critical. ...
