The Brazed Radiator purchases two stages of attention
In fact, when the Brazed Radiator is bought, there are two stages, the first stage is before the purchase. The second stage is to purchase, when the two stages are mastered, you can buy the high-quality Brazed Radiator. Let's explain it to the Brazed Radiator factory below.
The Brazed Radiator purchases two stages of attention
Three notices of Brazed Radiators:
1. For the separation heating system, the Brazed Radiator can be replaced now. For central heating system, it is not suitable to replace. Blind pursuit of beauty is likely to have an impact on home and neighborhood heating, or even personal safety. If must be replaced, must be operated by formal professional personnel.
2. Replace Brazed Radiators before and during decoration: it is best to change the Brazed Radiators before the heating period. According to gold flagship Brazed Radiator relevant experts, the current Beijing most of the village still use central heating, as a result, once in the heating period, the replacement of Brazed Radiator heating is bound to affect other users. There are also some unsafe factors, such as heating, and there is pressure in the heating pipes, which can be dangerous if not handled properly.
3. In addition, the replacement of the Brazed Radiator should be finished before the decoration, because the Brazed Radiator is a custom product, depending on the brand, the order period is 30 days to 40 days. Also, before the metope is decorated should turn the heater to take down, and according to the new heating dimension set good corresponding position.
When choosing Brazed Radiators, please pay attention to the following points:
1. Understand the district heating system
Gold flagship Brazed Radiator engineers, shijiazhuang, the heating system of water quality is not very good, urban central heating way is multifarious also, have a centralized computer, has the domestic hot water center, such as power plant waste heat heating, with an open non-pressure boiler heating, make the city heating hot water water quality difference is very big, some high oxygen content, some water more acidic, alkaline water quality. So before buying the Brazed Radiator, to the heating unit or community content canal to understand what is the heating system of this area form, according to the water quality characteristics of deciding what to buy the material of Brazed Radiator.
Generally speaking, the steel Brazed Radiator can not be used in open, pressure-free boiler or steam heating system; Aluminum alloy Brazed Radiator can not be used in heating system or steam heating system with high PH value; Copper tube aluminum foil (copper and aluminum composite) Brazed Radiator has no special requirement for water quality, but it is necessary to avoid the excessive torque of the coupling of the copper pipe and the copper tube of the header.
Secondly, the size of the original Brazed Radiator is recorded, and the size of the Brazed Radiator is selected according to the heat of the original Brazed Radiator. If you cannot obtain the original heat, you will need to estimate the size, orientation, floor and window size of your home.
2. Distinguish material characteristics from different materials according to water quality
The new Brazed Radiator, according to the material divided into soldering heat sink, aluminum alloy brazing steel radiator, copper Brazed Radiator, copper aluminum composite aluminum composite brazing Brazed Radiator, steel radiator, brazing stainless steel radiator, etc.; According to the characteristics of product shape is divided into pillar type Brazed Radiator column column (two, three, four pillars), exhaust pipe Brazed Radiator (single row, double row tube), blade Brazed Radiator (double blade, blade), finned Brazed Radiator (annular fin, rectangular fin), the cooling way is divided into radiation brazing Brazed Radiator, convection radiator, etc. The commonly used new-type Brazed Radiator is steel column Brazed Radiator, steel tube Brazed Radiator, aluminum alloy column wing Brazed Radiator, copper aluminum composite column wing Brazed Radiator.
Due to the properties of the material itself, aluminum alloy is resistant to acid and oxidation, but it is prone to alkaline corrosion. The strength of steel is high, capable of certain basic, but prone to oxidation corrosion; Copper corrosion resistance and other comprehensive properties are better, but the water sulphide or mixed copper in the water will also corrode, and the mechanical strength of copper is low. Countries for aluminum alloy Brazed Radiator and wall thickness below 2.5 mm steel Brazed Radiator, must be embalmed, coating anticorrosive coating, and aluminum alloy Brazed Radiator must adopt special non-metallic or double metal composite pipe, may not be directly connected to the steel tube aluminum threaded, to prevent electrochemical corrosion.
