HIGH FREQUENCY WELDED TP347H HFW SOLID FIN TUBE HEAT EXCHANGER PART

Overview

Helical Solid Finned Tubes are manufacturer by helically wrapping continuous fin strip on tube. HF Resistance Welding Usually Employs Frequency Of 400 kHz. The fin wound around the tube And Continuous weld. The fin strip is wounded spirally onto the tube and welded continuously with a high frequency electrical process to the base tube along the spiral root. The fin strip held under tension and confined laterally as it is formed around the tube, thereby ensuring that the strip is in forceful contact with the base tube surface. A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter, using the gas metal arc welding process. For a given tube or pipe size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height, fin thickness or number of fins per meter of length.

This welded steel finned tube configuration can be used for any practically heat exchanger application, and is particularly suited to high temperature and high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin-side temperatures. A continuous helical fin is attached to the base tube by high frequency electric resistance welding in order to give an efficient and thermally reliable bond.

HFW Solid Finned Tube's Function

• High frequency welded finned tube is a type of finned tube, which is mainly welded by high frequency welding and is a new type of excellent heat dissipation element. The high frequency welding finned tube is welded with high frequency current, the welding method is reliable and excellent, the welding seam is small, and the surface of the radiator is more solid as well as beautiful.
• High frequency welded finned tube is a heat sink element often used in finned tube radiators. Welding high-frequency welded finned tube on the base tube of the radiator improves the heat transfer coefficient of the heat exchanger side of the radiator and enhances the heat dissipation effect of the radiator, and the excellent heat dissipation effect makes the finned tube more and more popular.
• The high frequency welding finned tube is welded with high frequency current, which can increase the compactness of the radiator and improve the safety of the high frequency welding finned tube radiator in the operation process. The high-frequency welding process is an improved and upgraded process on the basic welding process, which is also a more excellent welding process.
• The more excellent welding process adopted for high-frequency welded finned tubes, the faster the welding speed and the narrower the weld seam, the more beautiful the appearance of the radiator. High-frequency welded finned tube has a simple and generous appearance, mainly in silver and gray, and can be suitable for a variety of styles of decoration, which is widely used in the field.
