How to tell if it is a refurbished radiator?

Nowadays, people advocate environmental protection and low-carbon life, and many waste and old things can be reused, but not all old items can be reused, such as refurbished radiators, which have great safety hazards when used. So, how to avoid buying refurbished radiators and buying *** radiators? Let's follow the golden flagship flag brother to find out.

What is a refurbished radiator.

Replace the two posts at both ends of the old radiator with a new one and repaint it to become a refurbished radiator. Refurbished radiators are difficult to see from the outside, but if you carefully identify the seams between the welds and the interface of the radiators, you can still see them. If the welds are not smooth and the seams of the joints are not sharp, then be careful, you may have bought a refurbished radiator!

Because the general manufacturer will polish the radiator very smooth before leaving the factory, the surface will be treated very smoothly and neatly, and there will be no sharp corners and deformations, and there will be no welding scars!

How to distinguish between good and bad radiators.

1.Radiator surface: First of all, see whether the surface of the radiator is painted to see whether it is shiny, whether the color is pure, whether the surface is smooth, and whether the solder joints are obvious. You can touch it directly with your hands to see if it feels smooth, and a smooth radiator is good.

2.Anti-corrosion in the radiator: you can look at the cross-section of the product, whether it is rough when touched by hand, and whether there is any paint peeling. If there is paint peeling or rough surface, it means that the corrosion resistance is not good.

3.The wall thickness of the radiator: China has strict requirements for the wall thickness of the radiator, if it is not convenient to measure, just lift it up and try it to see if the weight is moderate.

4.Heating heat dissipation problem: Compared with different brands, the same model and specification of products, the wider the radiator, the better the heat dissipation.

5.The material of the radiator: mainly divided into cast iron, steel, aluminum, copper-aluminum composite, etc., cast iron radiator is widely used, but now it is gradually eliminated because it is not easy to clean and consumes high energy.

Steel radiators are gradually accepted by users because of their functional requirements, but there are many kinds of steel, and it is still difficult to choose. If you are not very knowledgeable, it is recommended to use a well-known brand.

6.After-sales shelf life: shop around to understand how each merchant deals with the problems that arise during the product shelf life. If the after-sales is good, you can consider buying it.

The so-called "you get what you pay for", Jin Jin suggests that everyone should not be greedy for cheap and buy poor quality radiators. There are many kinds of radiators on the market, and all kinds of radiators are dazzling, but good radiators, their ** will not be too different, generally it is a matter of dozens of dollars, if the difference is too big, it is necessary to pay attention, you are likely to fall into the trap of the seller - buy a refurbished at a low price! So when buying, it's important to shop around.

If the refurbished paint surface will not be so uniform, it is recommended that you go to a specialty store or store to buy products from large manufacturers, which will be better. Rubens Heating hopes to help you.

To buy radiators, you have to go to the regular building materials city to buy.

Radiator is an important equipment for home heating in winter, but with the growth of use time, the appearance and internal structure of old radiators will age, corrosion and other problems, resulting in poor heat dissipation effect or water leakage and other problems. So, how to identify a refurbished radiator? What is the difference between a refurbished radiator and a new radiator?

If it is too long, you need to pay attention to its appearance and internal structure, especially whether the welds and surface are flat and smooth, and whether the internal structure is the same as the original radiator. The difference between a refurbished radiator and a new radiator shaker is in aspects such as service life and heat dissipation efficiency.

Refurbished radiators may have a shorter lifespan than new radiators, and they may not dissipate heat as efficiently as new radiators. False trust needs to be taken care of when buying to ensure that it can meet your own cooling needs.

What is a refurbished radiator.

Refurbished radiator refers to the repair and replacement of the appearance and internal structure of the old radiator after a series of technological treatments, so that it can regain the heat dissipation function of the radiator. Refurbished radiators are similar in appearance to new radiators, but differ in terms of longevity and heat dissipation efficiency.

The lifespan of a refurbished radiator may be shorter than that of a new radiator because its internal structure and materials may have some problems such as aging, wear and tear, etc. At the same time, the heat dissipation efficiency of a refurbished radiator may not be as good as that of a new radiator, as its internal structure and materials may be different from the original radiator, resulting in a decrease in heat dissipation efficiency.

How to distinguish refurbished radiators such as eggplant?

1. It is necessary to pay attention to the appearance of the refurbished radiator.

A refurbished radiator will look similar to a new radiator, but there may be some differences in the details. For example, there may be some marks in the welds of a refurbished radiator, and there may also be some imperfections in the surface. Therefore, when buying a refurbished radiator, you need to carefully observe its appearance, especially whether the welds and surfaces are flat and smooth.

2. It is necessary to pay attention to the internal structure of the refurbished radiator.

The internal structure of the refurbished radiator may be different, for example, the direction, size, shape, etc., of the pipe may be different from the original radiator. Therefore, when buying a refurbished radiator, you need to know whether its internal structure is the same as the original radiator and whether it can meet your own heat dissipation needs.

In the process of purchasing, you should choose the heating equipment that suits you according to the actual situation and needs of your family, comprehensively consider these factors; It is necessary to pay attention to the specifications and quality of radiators, and choose big brands compared with powerful manufacturers.

1. Radiator surface spraying: gloss, color, smoothness. First of all, when we buy a radiator, we should see whether the surface paint of the radiator is shiny and whether the color is pure and bright; Whether the surface solder joints are obvious or not, you can use your hands to touch the surface to judge whether it is smooth.

2. Anti-corrosion in the radiator: pay attention to the use environment of the radiator of various materials.

First, look at the appearance of the radiator.

The appearance of high-quality radiators, the gap of the radiator is uniform, the surface of the radiator is flat, if the radiator gap is uneven, the surface is uneven, such radiators are often of average quality, and may even be produced in small workshops.

Second, look at the radiator spraying.

The spraying effect of the radiator is good, the appearance can be good-looking, and the use can be longer. At present, the best process is to use imported, environmentally friendly professional plastic powder for electrostatic spraying, which can keep smooth and bright for a long time, durable, and easy to clean. The surface of the radiator that is not sprayed well is rough, not easy to clean, and it is easy to fall off, and the metal exposed inside is easy to rust.

Therefore, when we buy radiators, we must look at whether the surface paint of the radiator is shiny and whether the color is pure and delicate; Whether the surface solder joints are obvious or not, you can use your hands to touch the surface to judge whether it is smooth.

3. Look at the cross-section of the radiator.

Through the cross-section of the radiator to observe the worst, the general high-quality radiator cross-section is delicate, very tight, this radiator is strong and durable, will not expand and deform due to moisture. On the other hand, the cross-section of the radiator with poor material properties is very loose.

Fourth, look at the anti-corrosion in the radiator.

Different materials radiators use different environments, so the radiator anti-corrosion is more critical, here the user is best to see the cross-section sample product anti-corrosion, at the same time touch the inside is smooth, if rough means that the anti-corrosion is not done well, or some are painted will fall off the paint, you can pick off the nail to see if it is easy to fall.

Fifth, look at the installation and after-sales of radiators.

Many people think that everything will be fine when the radiator is bought, in fact, the correct installation of the radiator is also very critical, some families are not warm in winter, in fact, it is not that the radiator has a problem, but the early installation is not in place. When buying things, you have to shop around, especially for after-sales issues, compare the services of each merchant, and then see how to deal with after-sales.

Yicheng reminds you that it is best to go to a regular store and choose a well-known brand to buy. In addition to ensuring quality, there is also a complete installation and after-sales service guarantee system to avoid many problems such as unqualified products, non-standard installation, and inadequate service.

Take steel radiators, for example.

See how the details are handled.

The same type of product, the same performance, the same appearance, can not be distinguished, you can look at its details. You can see whether the corners of the heating are rounded, whether the radiator is smooth to the touch, whether there is unevenness, we often say that the details determine success or failure, a product, if the details are not done well, other places do not have to look.

Look at the heat dissipation fins.

The heat dissipation principle of the radiator is that the hot water flows into the sink, the heat conducts the heat dissipation fins, the hot air rises, and the cold air above the radiator is heated, so it circulates and heats the room temperature, so the heat dissipation fins are the key.

Look at the baking paintThe current radiator exterior paint is basically using the latest baking paint technology, which has heat resistance, moisture resistance, wear resistance and corrosion resistance. We all know that water quality has a certain corrosiveness, so the better the paint quality, the better the corrosion resistance and the longer the service life.

1. Heat dissipation.

High heating efficiency is an important indicator to measure the radiator material, a good radiator material has high transmission, fast heat dissipation, high stability, and can quickly increase the indoor temperature.

2. Corrosion resistance.

In a normal environment, any metal will suffer from oxidation corrosion, so the internal and external corrosion prevention of the radiator is more critical, with strong corrosion resistance, slow oxidation and corrosion speed, long service life, and is not prone to water leakage and bursting.

3. Material. Radiator radiators can be roughly divided into cast iron, steel, copper aluminum, aluminum, copper and other categories from the material, among which steel, copper and aluminum are more suitable for household use than other types, with a wide range of styles and affordable.

4. The heating is thick and thin.

There are relevant regulations on the thickness of the radiator, which affects the heat dissipation effect if it is thick, and it is easy to burst if it is thin, and if it is a place with complex water quality, the radiator will soon be corroded, which will make your radiator use less than a year.

5. After-sales. To choose a good brand, some people say that the warranty is 20 years, 30 years, 50 years, if it is a small company, can it really be opened for so many years, without your after-sales guarantee, you must choose a brand with a good reputation and strong strength to buy.

How to distinguish between good and bad radiator materials? What is a good material for radiators?

Qingdao Ruixue Zhao radiator is a focus on R & D and production: radiators, radiator brand radiator manufacturers, providing radiators and radiators, Ruihuate is a radiator brand manufacturer in China, radiator brand products are: steel radiators, copper-aluminum composite radiators, steel-aluminum composite radiators, new bathroom radiators, die-cast aluminum radiators, steam steel three-column radiators and other heating radiator products.

What brand of radiator is good? Please choose - Ruihuate radiator brand. As a radiator manufacturer with an annual production capacity of 4.6 million columns, Ruihuate radiator brand reputation has won the trust of the majority of users.

1. The efficient heat dissipation of radiators is indispensable: we live in a fast-paced era, high efficiency is the universal goal of modern people, and radiator heating is no exception, high heating efficiency is an important indicator to measure the radiator material, good radiator material has high thermal conductivity and large heat dissipation, so that the radiator has high heat dissipation, and quickly raises the indoor temperature in the fastest time to achieve multiple functional requirements of energy saving, economy and comfort.

2. The super ductility of the beautiful shape is indispensable: the traditional cast iron radiator is gray in color and often exposed with rust, which destroys the overall decoration style of the home, and no longer meets the aesthetic needs of modern home, and today's radiator has a fashionable and tidy appearance, which can be well integrated with home decoration, and even become a fashionable work of art, so that the production material must have good ductility, easy to design and shape, and the surface is smooth, and the paint adhesion is strong. It can well shape the fashionable and beautiful shape of the radiator, and then create an elegant home environment with the overall home decoration.

3. Fair and cost-effective: a good radiator in addition to comfort, efficiency and beauty, also needs a high cost performance, this is because most of the radiators are still ordinary small and medium-sized families, if the radiator is too high, many families will not be able to afford it, so the production of materials must be fair, the level is moderate, and the radiator manufactured can be accepted by most people.

4. Must have strong corrosion resistance: in ordinary environments, any metal will suffer from oxidation corrosion, but the degree of corrosion and strength are different. The corrosion-resistant metal is slower to be oxidized and corroded, and the radiator has a long service life and is not prone to water leakage and bursting.

Of course, with the development of modern science and technology, the process of anti-corrosion of metal is improving day by day, but this does not mean that the corrosion resistance of the metal material itself can be ignored.

5. To choose a good brand, some people often say that the warranty is 20 years, 30 years, 50 years, if it is a small company, can it really be opened for so many years, without your after-sales protection, you must choose a strong, reputable, first-class brand.
