How to Deal With Scaling in Steel Finned Tube Radiators

When scaling occurs on steel finned tube radiators, first analyze the structural reasons, and then use physical or chemical methods to remove scale according to the situation. You also need to pay attention to maintenance in the future.

1. Analysis of scaling causes

The main reasons for scaling in steel finned tube radiators are as follows:

Water quality problems: Water is too hard or contains a lot of impurities, which easily forms scale on the surface of the radiator.

Long-term use: Over time, minerals in the water will gradually deposit on the surface of the radiator to form scaling.

Temperature changes: Frequent changes in water temperature will cause dissolved substances in the water to precipitate, accelerating the formation of scaling.

Air humidity: A high humidity environment is conducive to the formation and adhesion of scale.

Cangzhou Datang Steel Pipe Co., المحدوده. has set a new industry benchmark for the HVAC and heat exchange fields with a more open concept, a more stable pace, a sense of urgency and a sense of mission that time is running out.

2. The impact of scaling on steel finned tube radiators

The impact of scaling on steel finned tube radiators is mainly reflected in the following aspects:

Reduced heat dissipation efficiency: The scaling layer will hinder the transfer of heat, resulting in a decrease in the heat dissipation efficiency of the radiator.

Increase energy consumption: In order to achieve the same heat dissipation effect, more energy is needed.

Shorten service life: Scaling will accelerate the corrosion of the radiator and shorten its service life.

Affect the appearance: Scaling will make the surface of the radiator rough and affect the appearance.

3. Treatment methods

For the problem of scaling of steel finned tube radiators, the following treatment methods can be adopted:

— Chemical cleaning method

The chemical cleaning method uses chemical solvents to dissolve the scale on the surface of the radiator. The specific steps are as follows:

Prepare cleaning agent: Select a suitable cleaning agent, such as phosphate, citric acid, etc.

Soaking cleaning: After diluting the cleaning agent in proportion, inject it into the radiator and soak it for a period of time.

Rinse clean: Rinse the radiator with water to ensure that the cleaning agent and scale are completely washed away.

Neutralization treatment: Use alkaline solution to neutralize the residual acidic substances to prevent corrosion to the radiator.

— Physical cleaning method

The physical cleaning method removes the scale on the surface of the radiator by mechanical means. Common physical cleaning methods include:

High-pressure water gun cleaning: Use a high-pressure water gun to spray the surface of the radiator and use the impact of the water flow to remove scale.

Brushing method: Use a soft brush or a special cleaning brush to gently brush the surface of the radiator to remove stubborn scale.

Ultrasonic cleaning: Use the vibration and cavitation effect generated by ultrasound to decompose and remove scale.

— Preventive measures

In addition to regular cleaning, some preventive measures can also be taken to reduce the formation of scale:

Soften water quality: Install water treatment equipment to soften the incoming water quality and reduce the mineral content in the water.

Regular sewage discharge: Regularly discharge the sewage at the bottom of the radiator to reduce the deposition of impurities.

Control water temperature: Avoid frequent changes in water temperature and keep the water temperature stable.

Keep dry: In a high humidity environment, try to keep the radiator surface dry to reduce the formation of scale.

4. Precautions

When cleaning steel finned tube radiators, pay attention to the following points:

Safety first: Pay attention to personal safety during operation and avoid using dangerous chemicals such as strong acids and alkalis.

Professional operation: For complex scaling problems, it is recommended to ask professionals to clean and maintain.

Protect the environment: The waste liquid generated during the cleaning process should be properly handled to avoid environmental pollution.
