Laser welding finned tube

Laser welding finned tube is one of the earliest and most successful inventions in the process of improving tube heat transfer. When used, this method is still all the various heat transfer methods of laser welding finned tube The most widely used one, not only suitable for single-fin tube heat exchangers, but also widely used in power, chemical, petrochemical, air conditioning and refrigeration engineering.
Laser welded finned tubes are widely used in chemical engineering, power engineering, air conditioning engineering, petrochemical engineering, and refrigeration engineering, such as surface air coolers, air heaters, and fan coils used in air conditioning engineering. The evaporator of the air cooler and the evaporator of the frost-free refrigerator used in the refrigeration project.
Laser welding finned tubes are not only suitable for the flow of single-phase fluids in the process of use, but their equipment is also of great value to the heat of phase transformation. Most of the finned tube heat exchangers used for clean gases use The new and efficient surface structure of the fins has achieved remarkable heat transfer enhancement effect.
Compared with other processes, the laser welding finned tube greatly saves the material cost to a high degree of penetration, and can effectively prevent the corrosion of its gaps during use, which will effectively extend it to a certain extent. The service life of the equipment reduces its heat transfer resistance.
In terms of quality control of laser welding finned tubes, its equipment mainly uses its CCD monitoring system during the production process to monitor the welding area throughout the process. The first piece is approved. The metallographic analysis system is used to obtain the welding status and ensure product quality Continue production after passing.

What is tube sheet layout?

What is tube sheet layout? A tube sheet is a component used in shell and tube heat exchangers and other types of heat transfer equipment. It is a flat plate with holes drilled in it, through which tubes are inserted and secured. The tube sheet serves as a barrier between the two fluids, allowing heat to be transferred from one to the other. The layout of the tube sheet depends on the design of the heat exchanger, which includes the number of tubes, the size of the tubes, and the spacing between the tubes. The layout is typically determined using computer-aided design (CAD) software, which can optimize the placement of the tubes to achieve the desired heat transfer performance. In general, the tubes are arranged in a triangular or square pattern on the tube sheet. The triangular pattern is often preferred because it provides better support for the tubes and reduces the risk of vibration and damage. The spacing between the tubes is also important, as it affects the flow rate and pressure...

What is aluminum finned tubes?

What is aluminum finned tubes? Aluminum finned tubes are a type of finned tube air heat exchanger that uses aluminum fins attached to a tube made of a different material, such as copper or steel. The aluminum fins are typically extruded or formed to increase the surface area of the tube, which in turn increases the efficiency of heat transfer. Aluminum finned tubes are commonly used in HVAC systems, as well as in industrial and power plant applications. They are preferred over other types of finned tubes in some applications because they are lightweight, corrosion-resistant, and have good thermal conductivity. Additionally, aluminum is relatively inexpensive compared to other metals commonly used in heat exchangers, such as copper and stainless steel. The specific properties of aluminum finned tubes can vary depending on the alloy used to make the fins. For example, aluminum fins made from alloys such as 6061 and 3003 have good corrosion resistance and thermal conductivity, while those...

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...
