The quality of heating water directly affects the service life of steel radiators. What are the requirements for water quality of steel radiators? This article focuses on the PH value, oxygen content, and minerals in water quality. illustrate. Let’s learn more about it with Brother Jinqiaqi.
As people have higher and higher requirements for home decoration, steel radiators have quickly occupied a place because of their beauty, toughness and lightness. Friends who have used radiators know that water quality has very high requirements on the material of radiators, especially steel radiators. The quality of heating water directly affects the service life of steel radiators. What are the water quality requirements for steel radiators?
Steel radiator requirements for the pH value of water: Steel radiators require that the system water pH value be greater than 7 and less than 12, and attention should be paid to matching the heating system of the community.
Requirements for the oxygen content of steel radiators in water: Because steel radiators are prone to oxidation and corrosion when exposed to oxygen, consumers who use open heating systems for heating should be careful when choosing steel radiators. After the heating season, fill the main system with water for maintenance, otherwise the radiator will be corroded and cause leakage problems.
Steel radiator requirements for minerals in the water: Chloride ions in the water are the main corrosive elements because they easily react chemically with steel, and then other metal ions in the water, in acidic or alkaline conditions Electrochemical corrosion is prone to occur under such conditions.
The service life of steel radiators: usually more than 5 years.
1. Product quality
There are many types of steel radiators on the market, and the quality varies. It is difficult to distinguish the quality from the appearance. Owners often want the price to be cheap, but they I don’t know if I have chosen a product of poor quality. The service life of such substandard products is about three to five years. The steel radiators of big brands generally use high-quality low-carbon steel as raw materials, which have excellent corrosion resistance. Through internal anti-corrosion treatment technology, their service life is more than ten years. Therefore, owners must choose big brand insurance when purchasing steel radiators.
2. Heating water quality
Water quality is always a factor that affects the service life of radiators. Radiators are more likely to be corroded in complex water quality. Consumers must make sure this before purchasing the product. To understand. If the heating water quality in the community is relatively messy, it is recommended that you choose a radiator with strong internal anti-corrosion, which can ensure the service life of the radiator to the maximum extent. If you are a self-heating user and can control the water quality yourself, then you can choose a medium-sized radiator with internal anti-corrosion, which can save a lot of money.
3. Factor 2 that affects the service life of steel radiators: correct maintenance
How to maintain also determines the service life of the radiator. In addition to its own quality and water quality, the service life of steel radiators is also an important factor affected by the correct maintenance by consumers. Some owners' wrong methods during use directly lead to the corrosion and aging of the radiator.
Knowledge expansion:
Let’s take a brief look at the water quality requirements for radiators made of other materials.
There is a saying in the radiator industry: "Aluminum is afraid of alkali, steel is afraid of oxidation corrosion, and copper is afraid of electrolyte." This means that aluminum radiators are afraid of corrosion by alkaline water and are not suitable for central heating. system, so aluminum radiators are not suitable in the north.
As for steel radiators, copper-aluminum composite radiators, and cast iron radiators, they are generally suitable for almost all north and south. However, steel radiators are usually said to be prone to corrosion, mainly because of the presence of oxygen in the heating system. As long as the water quality can be controlled to ensure that no fresh oxygen is added to the system, corrosion will naturally stop.
Of course, anti-corrosion diamond is also a good choice. The anti-corrosion diamond is jointly developed by the company and well-known science and technology universities in Beijing. It uses the principle of sacrificial anode to protect the cathode and uses magnesium-aluminum alloy which is more active than iron. The magnesium-aluminum alloy replaces the iron element and is gradually oxidized, effectively protecting the safety of steel pipes. The consumption time of a piece of magnesium-aluminum alloy is more than 15 years, which greatly extends the life of the radiator. No need to fill the water for maintenance, and the warranty is 15 years. It is a patented product that has the cost-effectiveness of steel and higher anti-corrosion performance than ordinary steel radiators.
If the community you live in has household heating, basically any radiator on the market can be used. If it is central heating, the choice needs to be made based on the water quality of the community. For example, if the oxygen content in the water is high, ordinary steel should not be used. Instead, anti-corrosion diamond or copper-aluminum composite radiators should be used.
Generally, copper-aluminum composite radiators do not have strict water quality requirements.
In addition, it is best for the radiator materials used in each room to be the same or similar to avoid corrosion due to electrochemical reactions between different materials.
