HF Welded Helical Finned Tubes is one of the most widely used spiral finned tubes, and is now widely used in power, metallurgy, waste heat recovery in the cement industry and petrochemical industries.

HF Welded Helical Finned Tubes is to use the skin effect and proximity effect of high-frequency current to heat the outer surface of the steel strip and the steel tube until the plastic state or melting, while the steel strip is wound around the steel tube, under a certain pressure of the winding steel strip. Finish welding. This high-frequency welding is actually a solid-phase welding. Compared with methods such as inlay, brazing (or integral hot-dip galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity and automation.

Helical Finned Tube

Features of high frequency welding fins

1. Due to the fast welding speed and strong self-cooling effect of the weldment, not only the heat affected zone is small, but also oxidation is not easy to occur, so the structure and performance of the weld are very good.

2. Anti-corrosion performance, wear-resistant performance, low contact thermal resistance, high stability, and anti-fouling ability.

3. Large heat exchange area.

HF Welded Finned Tube

HF Welded Helical Finned Tubes is a heat dissipation element often used in finned-tube radiators. Welding HF Welded Helical Finned Tubes on the base tube of the radiator improves the heat transfer coefficient of the heat transfer side of the radiator and improves the The heat dissipation effect of the radiator and the excellent heat dissipation effect make the finned tube more and more popular.

HF Welded Helical Finned Tubes is welded with high-frequency current, which can increase the compactness of the radiator and improve the safety of HF Welded Helical Finned Tubes radiator during operation. The high-frequency welding process is an improved and upgraded process on the basic welding process, and it is also a relatively good welding process.

The better the welding process adopted by HF Welded Helical Finned Tubes, the faster the welding speed and the narrower the welding seam, which improves the appearance of the radiator. The shape of HF Welded Helical Finned Tubes is simple and elegant, mainly in silver and gray, which can be suitable for various styles of decoration, and is applicable to a wide range of fields.

HF Welded Helical Finned Tubes

The welding speed of HF Welded Helical Finned Tubes is fast, which greatly improves the speed of processing and production. The finned tube has strong self-cooling property, which can cool down and cool down in a short time after welding, and prolong the service life of the radiator. The use of HF Welded Helical Finned Tubes in high temperature, high pressure, and highly corrosive environments can improve the heat dissipation efficiency of the radiator. It is used and welcomed by many people, such as boiler heat exchangers, economizers, waste heat recovery and other equipment have been widely used in a wide range of applications. It can be widely used in economizers, waste heat recovery equipment, boilers in power plants, greenhouse farming, greenhouses, petrochemicals, wood drying and other industrial fields.

HF Welded Helical Finned Tubes have strong adaptability and a wide range of applications, and have been widely used in various fields such as industry and agriculture. The operation method of HF Welded Helical Finned Tubes is simple, and the user can operate flexibly and simply to achieve the basic purpose of increasing the indoor temperature and providing indoor people’s comfort.
