high frequency welding of spiral finned tube finned tube
High Frequency Welded Spiral Fin Tubes. The high frequency welded spiral finned tube is one kind of tubular type efficient heat transfer element having spiral fins. The extended surfaces (fins) could be either solid or serrated create several to dozens of times of the heat transfer area than bare tube.
The high frequency welded spiral finned tube is one kind of tubular type efficient heat transfer element having spiral fins. The extended surfaces (fins) could be either solid or serrated create several to dozens of times of the heat transfer area than bare tube. China Spiral Steel Fin Tube Manufacturers, Suppliers The advantages of Spiral Steel Fin Tube:1. High production efficiency, continuous winding process. 2. Low cost, it relies on the characteristics of high-frequency welding itself - skin effect to heat the surface of the fin. tube to achieve the purpose of welding, no any filler metal material is required in the welding
Abstract:High-frequency welding spiral finned tube forming process and basic principles. Analysis of the high-frequency welding spiral finning reasons for the low pass rate. Through analysis and testing to prove, to improve the pass rate spiral finning following aspects should be: reasonably determine the platen width and groove depth to minimize diversion effect platen; adjust the Finning - Tulsa Fin TubeTulsa Fin Tube has chosen to continue making investments in the latest technology. We concentrate on what we do best, producing a full line of continuous, high frequency welded, helical or helically wound, spiral finned tube and finned pipe products using both solid and serrated fins.
HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes. Helical serrated finned tubse, serrated fins cut from metal strip and then helically wound around the tubes. Others are same as high frequency welded solid finned Tubes Pipes. Heat Exchanger High Frequency Welded Spiral Integral Fin High frequency welding spiral finned tube is a new type, wear-resistant and efficient heat exchange material, which is an efficient and energy-saving heat exchange element. It uses the national patent technology to use the high frequency welding production process, and uses the high frequency power supply as the heat source to heat the steel
The advantages of high frequency welding spiral fin tube:1. The simple and economic installation The maximum length of high frequency welding spiral finned tube can reach 6 meters, that reduces the join points, making the installation more economic, efficient, and also reduces the leakage probability of joints. 2. Easy maintenance High frequency finned tube - Murphy Fined Tubes & Fin Product description High-frequency finned tube works with high-frequency power source as a heat source, the steel strip, steel pipe heating at the same time, so that they melt into one.
9 rows · High frequency welded finned tube is one of the most widely used spiral finned tubes. High frequency welding fin tube-High Frequency Welded High frequency welded spiral finned tube is one of the most widely used finned tubes. It is a plain type fin, made by helically winding the fin strip on edge around the tube. The fin is continuously welded to the tube by a high frequency electrical resistance welding process which leaves the tube essentially unchanged metallurgically.
High-frequency welding spiral finned tube is wrapped in steel pipe, while the use of high-frequency current skin effect and proximity effect, on the outer surface of the pipe steel and heated until melted plastic state or, in certain pressure wound strip By the completion of welding. Such high-frequency welding solid as a solid phase soldering. Laser Welding Finned Tube - sunnysteelIn traditional the spiral fin tubes are using high frequency welding, resistance welding and other technology to make the stainless steel fin attached on the steel pipe. Laser Welding Finned Tube, the welding process has its shortcomings that cannot be overcome. Stainless
H-type tube, has a high rate of fusion welds and weld tensile strength. There is little contact resistance, and heat transfer performance and scalability are additional advantages. The H-fin tube is assembled with the H economizer, which has high efficiency, low resistance, and light weight. Compared to the traditional fin tube or spiral tube Spiral Serrated Fin Tube Welding Machine / Production Line Spiral Finned Tubes. High Frequency Welded Spiral Finned Tubes , Serrated Fin Tube For Heat Exchanger. Seamless Helical Spiral Wound Finned Tubes For Heat Recovery Steam Generator. Fired Heaters / Boiler Spiral Wound Finned Tubes SA 335 Gr.P91 Carbon Steel Material. Square Fin Tube
High-frequency resistance welding usually employs a current of 450,000 Hz. With this technique, the fin is edge wound encircling the tube to give a continuous weld. The forming of the fin around the tube and the heat of welding causes some upsetting or widening of the base of the fin, resulting in a contact area wider than the fin itself. Welding Spiral Finned Tube Boiler Economizer Savings Characteristics of Boiler H Finned Tube Economizer. 1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion. 2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row. 3).
Jun 17, 2020 · The high-frequency welding finned tube use the skin effect and proximity effect of the high-frequency current to heat the outer surface of the steel strip and the steel tube while the steel strip is wound around the steel pipe, until the plastic state or melting, a certain pressure on the wound steel strip Complete welding next.
