Seven Key Points of Finned Tube Radiator Purchase

Release time:

Jul 04,2023

How to choose a finned tube radiator is indeed a problem that consumers need to think about. Some customers pay attention to thermal efficiency and care about whether they can obtain obvious results in a short period of time; some focus on corrosion resistance due to environmental factors; and care about whether the appearance is beautiful, so on.

How to choose a finned tube radiator is indeed a problem that consumers need to think about. Some customers pay attention to thermal efficiency and care about whether they can obtain obvious results in a short period of time; some focus on corrosion resistance due to environmental factors; and care about whether the appearance is beautiful, so on.

So what are the most basic, can not be ignored? Finned tube radiator for you to sum up the following seven points:

First: the working pressure of the finned tube radiator should meet the working pressure of the system and comply with the current national product standards;

Second: civil buildings should use beautiful appearance, easy to clean the finned tube radiator;

Third: industrial buildings with high dust or dust-proof requirements should adopt finned tube radiators that are easy to clean;

Fourth: industrial buildings with corrosive gases or rooms with high relative humidity should use corrosion-resistant finned tube radiators;

Fifth: When using steel finned tube radiator, a closed system should be used to meet the requirements of the product for water quality. The heating system should be filled with water for maintenance in the non-heating season;

Sixth: the use of aluminum finned tube radiator, should be selected within the anti-corrosion type aluminum finned tube radiator, and meet the requirements of the product for water quality;

Seventh: choose a regular finned tube radiator manufacturer, with better after-sales guidance and installation, technical support, easy heating, and peace of mind.

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.
