Stainless steel heat exchange tubes and copper tube heat exchange tubes we can see the difference in material at first glance. So apart from the different materials, do you know the difference between them?
1. Generally, copper tube heat exchange tubes are less likely to scale than stainless steel heat exchange tubes. Foreign commercial boilers do not need water treatment equipment, but their lifespan can reach more than 15 years. This is because water forms scale on the copper tube wall, but because it generates flocculent scale, it is usually only necessary to increase the water flow rate when selecting, so that the scale cannot be deposited.
2. In terms of heat transfer performance: the thermal conductivity of copper tube heat exchange tubes is higher than that of stainless steel heat exchange tubes. Therefore, under the same conditions, the heat transfer coefficient of copper tube heat exchange tubes is better than that of stainless steel heat exchange tubes. The heat exchange tubes used on evaporators generally use copper tubes.
3. The strength of stainless steel heat exchange tubes is higher than that of copper tube heat exchange tubes. Generally, the plates of plate heat exchangers are made of stainless steel, but initially the plates are also made of copper.
4. In terms of price, copper tube heat exchange tubes are more expensive.
If long-term use is considered, stainless steel heat exchange tubes will be more suitable, because with the increase of use time, scale inhibition will be formed in the copper tube heat exchange tubes, thereby shortening the service life, while stainless steel heat exchange tubes will not, so the cost performance is higher.
