The main advantages of high frequency welding finned tube

Release time:

Jul 04,2023

The main advantages of high-frequency welded finned tubes are: high production efficiency, continuous winding production; low cost, it relies on the characteristics of high-frequency welding itself-skin effect to heat the surface of the workpiece to achieve the purpose of welding, welding process does not need to add any filler metal material; Since the high-frequency current only passes through the shallow surface of the steel pipe and the welding heat affected zone is small, it is not necessary to consider the additional wall thickness caused by the design calculation; the workpiece does not require heat treatment after welding.

High-frequency welded finned tube radiators have not only been greatly recognized and promoted in industrial heating and drying systems. In civil heating systems, the special status of finned tube radiators cannot be replaced by other specifications of products. For example, the use of medium and low pressure steam for civil heating operations, that is, as heat sink radiators, then heat sink radiators processed and manufactured by fin heat sink tubes are more worthy of recommend, the internal selection of the fin heat pipe seamless steel pipe as the base pipe. External matching steel or aluminum heat dissipation fins, the heat dissipation plate produced in the pressure performance and heat dissipation performance are very good.

Characteristics and application fields of high frequency welding finned tube radiator

The base tube and the fin are firmly welded, the contact thermal resistance is small, the sheet distance is uniform, the wrinkle is small, it is not easy to accumulate dust, and the heat exchange efficiency is greatly improved. It is widely used in the waste heat recovery of heating furnaces, boilers, kilns, hot air furnaces and drying towers. Compared with traditional wound-tube air coolers, the outstanding advantages of high-frequency welded finned tube radiators are large heat dissipation area and cooling capacity. High, low air resistance, and its performance remains basically unchanged with the increase of service life.

How to buy SRZ finned tube radiator

The base tube of the traditional SRZ finned tube radiator is generally Φ 21*2 stainless steel or carbon steel tube, the height of the strip steel used for winding the sheet is 15mm, and the sheet distance is 5-8mm. The thickness of the sheet is generally 0.23-0.38mm.

Advantages of spiral high frequency welding finned tube

As a commonly used heat exchange element, high frequency welding finned tube needs to work for a long time under high temperature flue gas environment. For example, finned tubes used in boiler heat exchangers are used in harsh environments, high temperature and pressure, and corrosive environments. High-frequency welded finned tubes should have high-performance indicators, mainly including: corrosion resistance, wear resistance, low contact thermal resistance, high stability and anti-fouling ability.

Advantages of finned tube radiators

The finned tube radiator is not easy to ash. The cause of dust accumulation is the Karman vortex gap. Ash deposition will affect the flow of steam in the pipeline, and then affect the heat transfer efficiency of steam. After hot-dip galvanizing, the gap of the heat pipe is reduced, and it is not easy to form a dust accumulation angle, which affects the heat transfer efficiency. The integral finned tube radiator has stable performance and long service life. The thermal test has stable heat transfer performance and is suitable for various drying chambers and large and medium heating systems. The heat transfer efficiency is high, the corrosion resistance of the entire hot-dip galvanized layer is improved, and the service life is extended.

How to choose the material of finned tube radiator

The choice of finned tube radiator material determines the life of the heat exchanger and the cost of the equipment. When we choose the material according to the working conditions, we can choose the radiator with high cost performance, thereby reducing the production cost of the enterprise.
