The difference between stainless steel tube heat exchanger and copper tube heat exchanger we can see literally, the two use different materials, one is stainless steel, the other is copper. That's the difference in material. When we choose these two kinds of tubes, we will consider the heat transfer performance and corrosion resistance.

We all know that copper pipe is less likely to scale than stainless steel pipe. Foreign commercial boilers are not water treatment equipment, but the life is as long as 15 years. The reason is that, although water can form scale on copper pipe walls, it only forms floccule scale, which can't settle as long as the water velocity is increased.

The next is to consider the heat transfer performance. The thermal conductivity of copper is higher than that of stainless steel, so the heat transfer coefficient of the same shape of copper tube is higher than that of stainless steel tube. So the heat exchanger tubes used on the evaporator condenser are basically made of copper.

Third, the strength of stainless steel is higher than copper, so now we see the plate of the plate heat exchanger is stainless steel, but the original plate is also copper. Of course, the price of copper is much higher than stainless steel.

We should take various factors into consideration when choosing heat exchanger. There are more stainless steel tube heat exchangers in the market now, which makes the stainless steel heat exchanger tube industry has achieved considerable development.
