The  high-frequency induction welding  process is currently a commonly used welding process in the field of pipelines. Its high efficiency and environmental protection characteristics have attracted the favor of many pipe welding producers and have been widely used. In practical applications, high-frequency straight-seam induction welding was originally applied to the welding of ordinary carbon steel, that is, the welding application of ordinary materials. With the maturity of high-frequency induction welding technology and the technological advancement of high-frequency welding machine power supply, the current high-frequency straight-seam induction welding technology has been applied to the welding of some special materials, including aluminum alloy, copper, stainless steel and other metals The pipeline welding of materials provides pipeline manufacturers with a new way to manufacture products and innovates the traditional production technology of some products.

Compared with other technologies, laser-welded stainless steel finned tube can greatly save material cost and achieve high penetration rate, effectively prevent the corrosion of its gap during use, thus effectively extend the service life of its equipment to a certain extent, and reduce the thermal resistance of its heat transfer. In terms of quality control of laser-welded stainless steel finned tube, its equipment mainly adopts its CCD monitoring system in the production process, monitors the welding area in the whole process, approves the first piece, USES the metallographic analysis system, obtains the welding status, and ensures the product quality qualified before continuous production. www.murphyfinnedtubes.com Laser-welded stainless steel finned tubes are widely used in chemical engineering, power engineering, air conditioning engineering, petrochemical engineering and refrigeration engineering, such as surface air cooler, air heater, fan coil used in air conditioning engi...

Finned tube heat exchanger still belongs to shoulder-arm heat exchanger to a certain extent. The main feature of the finned tube heat exchanger is that it has an extended heat transfer surface. Therefore, in the process of heat transfer, it is not only carried out on the primary heat transfer surface, but also on the secondary heat transfer surface. The heat of the medium on the high temperature side is not only poured into the medium on the low temperature side once on the surface, but also transfers part of the heat along the fin surface height direction, that is, along the fin height direction, there is a partition poured into the heat, and then pass the heat to the medium on the low temperature side. www.murphyfinnedtubes.com Finned tube heat exchanger in the production of the material will have a certain degree of thermal resistance, in the use of the direct and heat dissipation is inversely proportional, that is to say, the higher the thermal resistance, the lower the h...

The amount of heat dissipated in the finned tube is virtua l amount, that cannot be touched. If it is not measured, calculated or installed improperly, it will easily affect the heating. Therefore, Murphy  can take some measures in a targeted manner, such as increasing the number of finned tubes of the radiator, because the flow of water flowing through the radiator per unit time is constant, then the finned tube is added to the outer wall of the radiator. C an achieve the effect of increasing heat dissipation. https://szmurphy.en.alibaba.com/product/62419157392-811592052/Murphy_Copper_boiler_laser_welding_heat_exchanger_Laser_Welded_Finned_Tubes_heat_exchange_for_Solar_Water_Heating.html?spm=a2700.icbuShop.41413.31.298c6a21Pr1iAi Now the finned tube heat sink material has a certain thermal resistivity, which is inversely proportional to the heat dissipation, that means , the higher the thermal resistivity, the lower the heat dissipation. Therefore, if you want to increas...

As flat fin heat exchanger is simple and convenient in structure and manufacture, durable in use and good in applicability, so far, the heat exchanger widely used in Refrigeration Engineering (such as evaporator of ammonia cooling fan, surface air cooler, etc.) still widely uses rectangular flat fin as expansion surface. Rectangular flat fin has the advantages of simple and compact structure, convenient defrosting, easy manufacturing and so on. At the same time, because it only depends on increasing the heat transfer area to enhance the heat transfer, the heat transfer effect is poor, especially in the heat exchanger with phase change heat transfer of fluid in the tube and forced flow heat transfer of air outside the tube, the heat resistance of the air side is still the main heat resistance in the whole heat transfer process despite the addition of fins. https://szmurphy.en.alibaba.com/product/62414426747-811592052/Murphy_Stainless_steel_finned_tubes_laser_welded_cooling_Delivery...

Finned tube is a heat exchange element. In order to improve the heat exchange efficiency, usually on the surface of the heat exchange tube by adding fins, increase the surface area of the heat exchange tube (or internal surface area), so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange tube. A manual suit is called a manual suit. It is by means of tools, relying on human power to press the fins into one by one. This method because of the limited pressure of the fin, the interference of the suit is small, the fin is easy to produce loose phenomenon. https://szmurphy.en.alibaba.com/product/62413143114-811592052/Murphy_Carbon_steel_finned_tubes_laser_heat_exchanger_Laser_Welded_Finned_Tubes_heat_exchange.html?spm=a2700.icbuShop.41413.29.2a116a21a3Zp9a The helical finned tube of integral hot-dip galvanizing is adopted, because it is limited by the thickness of galvanizing layer (when the galvanizing layer is thick, the zinc layer is weak in...
