Three Mistakes in Maintenance of Finned Tube Radiator

The good maintenance of the finned tube radiator can guarantee the heating effect of the radiator and increase the service life of the radiator. However, if the repair method is improper, it will also bring adverse effects. There are three errors in the maintenance of the finned tube radiator:

Mistake 1: Wrong the radiator.

After the radiator is wrapped, there will be a sanitary dead corner on the cover, which is easy to breed bacteria and dust. When heating next year, the accumulated dust and bacteria will fly all over the house with air convection, affecting the indoor environment and causing harm to family health.

Mistake 2: Aluminum radiators are not afraid of corrosion.

This view is wrong. Aluminum radiator has strong oxidation resistance and corrosion resistance, but it is prone to alkali corrosion and chloride ion corrosion. Therefore, it is necessary to avoid contact of the aluminum radiator with alkaline (pH> 7) or high chloride ion content to avoid corrosion and water leakage.

Mistake 3: If the water in the radiator is poured out and kept dry, the radiator can be better maintained.

This view is wrong. Because the water in the radiator has been treated with anti-corrosion, anti-mold, anti-rust, and anti-fouling, the oxygen content in the water is very low, and the radiator is not easy to rust. If the water is released, the oxygen content in the air is higher than the oxygen content in the water. If the heat sink contacts the oxygen in the air in a large area, the oxidation reaction is more likely to occur and the oxidation is faster. Therefore, if the water is poured out, the radiator will be more rusty and dirty, which will seriously affect the service life.

The maintenance of the finned tube radiator is necessary, but the above errors should be avoided, so as not to affect the service life of the finned tube radiator due to improper maintenance.

Focus on hot spots

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.
