Pipe Welding, Pipe Production Line, Tube Mill manufacturer / supplier in China, offering Carbon Steel Automatic High Frequency Tube Making Machine, T89b T90b Steel Profile Production Line Elevator Guide Rail Machinery, High Speed Motorcycle Rim Steel Profile Roll Forming Machine Iron Ring Making Machine and so on. China High Frequency Welded Fin Tube Suppliers The fin is continuously welded to the tube by a high frequency electrical resistance welding process which leaves the tube essentially unchanged metallurgically. The width of the weld is always greater than 90 percent of the thickness of the fin, assuring a strong bond between the fin and the tube for efficient heat transfer and long life. Electric resistance welded (ERW) pipe ASTM A234 butt Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.Initially this manufacturing process used low frequency A.C. current to heat the edges.
The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces an homogeneous, clean and continuous fin-totube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion. High Frequency Induction (HFI) Welded Pipe - Sunny SteelIn High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.

Jan 17, 2018 · Date:2018-03-14 View:1718 Tag:High frequency welding effect on steel pipe In the process of high-frequency welding of steel pipes, the control of the welding process and process parameters, the position of the induction coil and the location of the resistance have a great influence on the welding quality of the steel pipe welding. Manufacturing process of high frequency welding finned tubeJun 17, 2021 · The manufacturing process of high frequency welding finned tube. The welding of high frequency welding finned tube is roughly divided into the following processes:(1) Purchasing and re-inspection of steel pipes:The steel pipes should be purchased in accordance with the standards and technical terms required by the drawings; re-inspection must be carried out carefully after returning to Selecting a welding frequency - The FabricatorDec 11, 2003 · High-frequency welding is a very forgiving process when used on low-carbon steel; good welds can be achieved over a range of frequencies. However, better weld quality can be achieved by carefully researching the results achieved with different weld frequencies.
Ferrite for high-frequency tube welding. We offer a full range of consumables including coils, ferrite, impeders and tube scarfing equipment. This new Compact Weldac measures less than 1300 mm in height, 1500 mm in length and 500 mm in width. The worlds most compact one-cabinet 300 kw Welded Finned Tube - Air Cooled Heat ExchangersHigh-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. Welded Metal Tube Basics, Value and Weld Types Wasatch A high-frequency welding power source will be obtained and activated. Leads from the power source will be placed very near the formed, but unwelded tube. The leads placed near the tube will begin to emit high-frequency energy, controlled by the manufacturer.
