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.   What 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 (us...

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...

H-shaped finned tube or square finned tube advantages

H-shaped finned tube or square finned tube advantages: H-shaped finned tube or square finned tube adopts a new welding process. A number of zigzag structures are used at the welding contact parts of the fins, so that the heating is uniform, the welding surface is uniform, and the surface is smooth. There is no slag inclusion, porosity and weld beading. The welding fusion rate is up to 97%. Due to the uniform heating, the compression plastic deformation generated in the welding process is reduced, the longitudinal residual tensile stress near the weld is reduced and the residual compressive stress borne by the fin far from the weld is greatly reduced, which can significantly reduce the wave deformation of the fin and make the welding quality of H-shaped fin tube meet the requirements of technical conditions. H Shape Finned Tube Typical Material and Size H Shape Finned Tube Base Tube Size φ 32*4 φ32*5 φ38*4 φ38*5 φ42*5 φ48*5 φ51*5 φ51*6 H Shape Finned Tube Fin Size 70mmX70mm 、 75mmX75mm...
