radiator is already an indispensable heating equipment for winter heating in our northern region. However, do you still remember the excellent characteristics of the radiator you mentioned? Today, Consprite radiator takes us to the factory for on-site evaluation! Whether the quality is good or not will be given to you during the heating season!
Detection 1: Spraying process of the surface of the radiator
When choosing a radiator, we can see if the surface paint of the radiator is glossy enough and whether the solder joints on the surface are obvious, and then touch the surface of the radiator with your hands to see if it is smooth.
Detection 2: The wall thickness of the radiator
When many people buy radiators, some businesses will claim that their radiator has solid and durable wall thickness, but this is not the case. The wall thickness of the radiator should not be too thick. If it is too thick, not only will the radiator be bulky and the heat dissipation effect be good, but the radiator that is too thin will not have enough pressure resistance. Of course, the thickness standards of different materials are also different, and our country also has standards and specifications for the wall thickness of radiators.
National standards for the wall thickness of radiators of each material are as follows:
Steel radiator wall thickness is generally above 1.2mm. 1.2mm-1.6mm is thin steel radiators, and those above 1.8mm are thick steel radiators;
Copper-aluminum composite radiator wall thickness, copper: horizontal pipe is 0.8mm, vertical pipe is 0.6mm, aluminum: 0.6mm;
Detection 3: The internal anti-corrosion layer of the radiator
Due to the material reasons, steel and aluminum radiators have anti-corrosion layers, which is a key technology that determines that the radiator is not prone to leakage and bursting. The quality of anti-corrosion performance is also the key to the quality of steel and aluminum radiators.
On the market, in order to save costs, many manufacturers have saved some treatment links of the internal anticorrosion layer. The surface treatment of the radiator does not meet the requirements, the coating thickness does not meet the standards, and it is easy to swell and fall off. Some of them only have internally coated radiators. After soaking in hot water for a few days, large-area bubbles occur, radiator coating peels off, and substrate rust... It can be imagined that this internal anticorrosion is simply useless.
Therefore, consumers should carefully choose when purchasing anti-corrosion radiators. Do not trust the merchant’s publicity. It is best to check their cross-sectional samples and touch with your hands whether the inside of the radiator is smooth. If it is rough, it means that the anti-corrosion is not done well, or some are painted and painted. You can use your nails to check whether it is easy to lose paint.
The internal anticorrosion materials of regular brand radiators are shot in high pressure, without dead corners or bubbles, and have good corrosion resistance; the industry-leading fully automatic vacuum filling internal anticorrosion process can be used to spray the anticorrosion coating on the inner wall of the radiator under a vacuum negative pressure environment. The coating has strong adhesion and is not easy to fall off. The anticorrosion layer can last for a long time, avoiding corrosion of the radiator.
Detection 4: Welding quality of radiators
As we all know, radiators are welded by different parts, so the welding quality has a great impact on the quality and service life of the radiator. When purchasing radiators, you can pay more attention to the welding parts of the radiator. Generally speaking, the welding parts of good radiators are uniform and smooth. Some businesses do not have good welding processes, and the welding parts of the radiator are rough and uneven, and the welding is not flat and has disadvantages such as welds, which can easily lead to water leakage and other accidents.
Detection 5: After-sales guarantee of radiators
When purchasing radiators, we have to compare prices, especially after-sales issues. Compare the services of each radiator merchant and the services of radiator manufacturers, and then check the corresponding warranty period of radiator, and how to deal with after-sales issues.
