In which aspects are the superior performance of steel finned tubes more mature

With the development of industry in our country, steel finned tube radiators for heating and heat exchange have gradually emerged and stood out. Its standard model structure consists of a steel frame and a heat dissipation pipe. The heat dissipation pipe is made of steel pipe spiral wound fins, which are then processed by integral hot-dip galvanizing technology to form an integral finned pipe with good air tightness, compact structure, and convenient installation. Its advantages are as follows.

The integral steel finned tube radiator has stable performance and long service life. After thermal testing, the heat transfer performance is stable, suitable for various drying rooms, large and medium-sized heating systems, and has high heat exchange efficiency. The overall hot-dip galvanizing is used to improve corrosion resistance and extend service life.

The integral steel finned tube radiator is not prone to dust accumulation. The reason for ash accumulation is often caused by the Karman vortex gap, and excessive ash accumulation can affect the steam flow rate inside the base pipe, thereby affecting the heat transfer efficiency of the steam. After the overall hot-dip galvanizing, the gaps in the heat dissipation pipes are reduced, which makes it less likely to form dead corners and affect the heat transfer efficiency.

The overall steel finned tube radiator has more uniform heat transfer. After hot-dip galvanizing, the base tube and fins are formed as a whole, with consistent structural stress and stable performance. The fins are in a sand dune shape, which is consistent with the temperature gradient shape when heated. When heated, the outer surface temperature of the fins is consistent, and the thermal stress is uniform, without concentration or weak points, making the heat transfer effect more ideal.

Finned tube radiators - advantages of steel finned tube radiators

The steel finned tube convection radiator is composed of a heat dissipation inner core convection cover, mainly for convection heat dissipation. It has high heat dissipation efficiency, rapid temperature sensing of the room, good decoration, easy harmony with the indoor environment, light weight, active convection cover, easy installation and maintenance, economic and energy-saving, and environmental protection characteristics.

The wall thickness of the base tube of the finned tube is close to that of the heating pipeline (over 2.5mm), which greatly improves the corrosion resistance of the radiator; The surface of the convection hood is treated with electrostatic spraying, which has strong adhesion and a smooth and beautiful surface. The high corrosion resistance of the heat dissipation core and the special treatment of the convection hood make the service life of the radiator reach more than 20 years.

Steel finned tube radiators - Product characteristics of steel finned tube radiators

1. Metal has high heat and heat dissipation efficiency, with a wide range of applications. The heat medium can be hot water, steam, thermal oil, etc.

2. The pressure bearing capacity is high, 4-5 times that of traditional cast iron radiators.

3. The appearance is novel and beautiful, with a small volume and light load-bearing capacity, which is 1/6 of that of cast iron radiators.

4. Easy to install, the inlet and outlet can be designed as needed without the need for auxiliary structural components, saving installation time by 90%.

5. Good comfort. Due to the predominance of convective heat transfer, the temperature throughout the room is uniform.

6. Long service life. The base tube of the finned tube has a thick wall and similar material to the heating pipeline, so it has the same lifespan as the heating pipeline.

7. It has the characteristics of water conservation (90%), energy conservation, and environmental protection.
