Our company has accumulated many years of experience in high-frequency welding Finned Tubes , square finned tubes, Inlaid Finned Tubes, and rolling composite steel and aluminum Finned Tubes.
Laser welded spiral Finned Tubes are used in civil wall-hung boilers, industrial boilers, etc., using German technology, which has a history of more than ten years in Europe. The advantage is that the contact thermal resistance is zero, and compared with high-frequency welding Light, small thermal resistance, High Penetration Rate, and the assembled Heat Exchanger has the characteristics of compact size, more Energy Saving and environmental protection, and meets the national emission requirements
Laser Welded Finned Tubes are processed by laser welding machines. Laser welding is a welding method that irradiates a high-intensity laser beam onto a metal surface. Through the interaction of laser light and metal, the metal absorbs the laser light and converts it into heat, melting the metal to form cooling crystals. Laser welding machine is the most advanced laser welding equipment for Finned Tubes. Since the welding process is fully automatic and mechanical, the technological content and quality of laser welded Finned Tubes are superior to traditional cooling Tubes.
Laser-welded Finned Tubes have a fully automatic welding process, which saves labor costs; secondly, the Laser Welded Fins are Firm , sturdy, and pass the test with high tensile strength. Laser welding is more efficient.
Advantages of laser welding finned tubes
Laser welding Finned Tube (Finned Tube) fin machine has a high degree of automation, the welding of fins and tubes is synchronized with the winding of tubes
The welding rate is 100%, and the laser welded Finned Tubes and fins are firm, and the welding strength exceeds 600MPa.
The precision of the laser welding pipe finishing machine can reach 0.05mm
The advantages are of decisive importance compared to conventional MAG/HF welding. The complete connection of the Fins to the base tube leads to excellent heat transfer, and the thermal performance of the finned tubes is increased by 2.5 times. Continuous welding prevents the notch effect, thereby avoiding V-corrosion and crack formation under conditions where Finned Tubes can swing. The heating degree of the base metal is low during the welding process, and the traveling speed is as high as 20m/min. Minimize the heat-affected zone in the substrate pipe.

As a heat exchange element, finned tubes work in high temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in a corrosive atmosphere. This requires finned tubes to have High performance. index.
What is a finned tube?
Finned tubes are a family of tubes used in applications involving the transfer of heat from a hot fluid to a cold fluid through the tube walls. In other words, a finned tube uses its "fins" to increase the surface area for external fluid contact. The tubes then exchange heat between the fluid inside the tube and the fluid outside the tube. These tubes are usually made of Stainless steel, especially the 300 and 400 series, because the specialty metal has some key properties.
1), anti-corrosion performance
2), wear resistance
3), low contact thermal resistance
4), high stability
5), anti-fouling ability
Inspection method and process of Finned Tube
During operation, before on-site detection, the delay time from the sound detector to the receiving system is measured, and the sound time correction value is calculated. During the measurement, the transmitting and receiving probes should rise and fall synchronously at the same height or maintain a fixed height difference. The distance between the measurement points is 40cm, and it will be dense to 20cm when abnormal
The Finned Tube selects the proper launch voltage and amplifier gain, which remain constant during retesting. Display and record the time history curve of the received signal in real time. Two finned tubes are used as a detection section for complete assembly, and multiple sections are tested separately.
