Lord Fin Tube-High frequency welding of spiral fined tube

What is high frequency welding spiral fined tube?

High frequency welding spiral fined tube is a new type of heat transfer material with wear resistance and high efficiency. It is also a type of high efficiency, energy-saving heat transfer element.

High frequency welding spiral fined tube uses high frequency welding spiral technology, a national patent technology that uses high frequency power supplies as the heat source to simultaneously heat the steel strip and steel pipe, allowing it to be welded together as a whole. This technology has properties such as high thermal efficiency, large heat dissipation area, long service life, temperature range adaptation, high pressure, and so on.

Waste heat recovery, petrochemical industry, power plant boiler, economizer, civil building heating, refrigerating, drying, wood drying, food drying system, and other industries make extensive use of it.

The benefits of high frequency welding spiral fined tube :

1. High frequency welding spiral Fined tube is easy and inexpensive installation

The maximum length of a high frequency welding spiral finned tube is 6 meters, which reduces join points, making the installation more economical and efficient, as well as lowering the likelihood of joint leakage.

2. High frequency welding spiral Fined tube is simple upkeep

High frequency welding spiral fin tube does not need to be maintained after installation.

3. High frequency welding spiral Fined tube has high effectiveness

The heat dissipation area of a high frequency welding spiral fin tube is more than eight times greater than that of a light tube. Because the internal is smooth, the internal flow resistance is low.

4. High frequency welding spiral Fined tube can extended service life

Fins and pipes with high mechanical strength, with tensile strengths exceeding 200 mpa. Hot dip galvanized processing is used on both the inside and outside of the tube.

Carbon steel, stainless steel, alloy steel, and corrosion resistant steel are all weldable fin materials.

High frequency welding spiral fined tube is a kind of heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the external surface area (or internal surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency.

High frequency welding spiral Fined tube is one of the most widely used spiral Fined tubes. It is widely used in power, metallurgy, cement industry waste heat recovery and petrochemical industry. High frequency welding of spiral Fined tube is carried out when the steel strip is wound around the steel pipe.

High frequency welding of spiral Fined tube is by using skin effect and proximity effect of high frequency current, the steel strip and steel pipe outer surface are heated until plastic state or melting, and welding is completed under certain pressure of winding steel strip. This kind of high frequency welding is a kind of solid phase welding. Compared with inlay, brazing (or integral hot galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity and automation.
