In a heat exchanger composed of ordinary steel pipes (smooth tubes), in many cases, the heat transfer coefficient of the fluid outside the tube and the fluid inside the tube to the tube wall is different. The so-called heat transfer coefficient refers to the heat transfer amount per unit heat transfer area and unit temperature difference (the temperature difference between the fluid and the wall). It represents the heat transfer capacity between the fluid and the wall. For example: The heat transfer coefficient when water condenses on the wall is: 10000-20000w/(m2. ℃) The heat transfer coefficient when water is boiling on the wall is: 5000----10000---- when the water flows through the wall The heat transfer coefficient is approximately: 2000----10000---- The heat transfer coefficient when air or flue gas flows through the wall is: 20----80---- The heat transfer coefficient when air is naturally convective is only: 5----10---- It can be seen that the difference in heat transfer capacity...

Why we choose stainless steel finned tube Sophisticated processing technology for stainless steel finned tubes In the production process, the laser welding stainless steel finned tube is mainly made of 304 stainless steel. It is mainly used for the heat exchange of two media when it is used. The 304 stainless steel finned tube has excellent technology. It is an alternative product for heat exchange and waste heat recovery in boiler, power generation, petrochemical, HVAC, refrigeration, air conditioning and other industries. Laser welded stainless steel finned tube can effectively improve the efficiency of its heat exchanger during use, to a certain extent, effectively extend its life, reduce volume and save materials, the whole rolled finned tube has no contact thermal resistance, heat transfer Good performance, high strength, heat resistance vibration and mechanical vibration, good thermal expansion performance. Laser welded stainless steel finned tube has the characteristics of high ...

Laser welding finned tube is processed by laser welding machine. Laser welding is a welding method that irradiates a high-intensity laser beam onto the metal surface. Through the interaction of the laser and the metal, the metal absorbs the laser light and converts it into heat, melting the metal to form a cooling crystal. Laser welding machine is the most advanced laser welding equipment for finned tubes. Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welding finned tubes are superior to traditional cooling tubes. The laser welding finned tube has a fully automatic welding process, saving manpower costs; secondly, the laser welding fin is firm, strong, and the test with high tensile strength is qualified. Laser welding is more efficient. Advantages of laser welding finned tube The laser welding finned tube (finned tube) fin machine has a high degree of automation, and the welding of the fin to the tube and ...

High efficiency pitted tube refers to make enhancement to the ordinary inside and outside smooth surface of the heat exchange tube, so that the overall heat exchange effect can be significantly improved. High efficiency pitted tube Application Mainly used in lithium bromide air conditioning (non-electric air conditioning) and other industries High efficiency pitted pipe refers to make enhancement to the ordinary inside and outside smooth surface of the heat exchange tube, so that the overall heat exchange effect can be significantly improved. Strengthening form : to the internal and external surfaces of the heat exchange tube, through extrusion and rolling, processing a variety of shapes (spiral squamous tooth, bump and groove, etc.), to change the constant liquid flow field distribution, formation of turbulent flow, or to improve the effect of convection. Meantime through the physical form processing, extending internal and external surface to increase the heat transfer area of the i...

The high-frequency welding finned tube is to use the skin effect and proximity effect of the high-frequency current to heat the steel strip and the outer surface of the steel tube while the steel strip is wound around the steel pipe, until the plastic state or melting, under a certain pressure of the wound steel strip Complete welding. This high-frequency welding is actually a solid-phase welding. Compared with inlaying, brazing (or integral hot-dip galvanizing) and other methods, it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity, and degree of automation . Adopt high-frequency current, welding while winding, so the base tube and the fin are basically integrated, and the welding rate is an important indicator to judge the quality of the fin tube. (1) Marking method of high-frequency welding finned tube and fin structure First, use CPG to represent the abbreviation of CHIPIAN GUAN. The structural characteristics, materials, and proces...
