Copper tube heat exchange effect is good:

1, the thermal conductivity of copper tube is 100W/m℃, the thermal conductivity of stainless steel tube is 13W/m℃, if other conditions are the same, the heat exchange effect of copper tube is better,

2, copper tube for strength and wear reason, wall thickness not less than 1.2 mm, wall thickness of the stainless steel pipe can be thin to about 0.5 0.8 mm, according to the law of thermal resistance of thermal conductivity, thermal conductivity constant, the smaller the thickness of the wall tube, the smaller the thermal resistance of thermal conductivity, heat transfer coefficient is larger, so can reduce the wall thickness of stainless steel pipe to reduce and copper pipe, the overall heat transfer coefficient between the

3. Although the overall heat transfer coefficient between the stainless steel tube and the copper tube is shortened by reducing the wall thickness, it is only shortened. Generally speaking, the heat transfer effect of the copper tube is better.

4, as the growth of the time, there will be more thick copper oxide, internal dirt will also more and more, the heat transfer effect will be more and more bad, basic no oxidation and stainless steel, calculate oxidation also slowly, therefore, copper tube heat in effect from the beginning is better than stainless steel tube, with the passage of time, the heat in the effect will be worse and worse, The heat transfer effect of copper tubes used for a long time is worse than that of stainless steel tubes.

Advantages of stainless steel heat exchange tube:

1, stainless steel heat eunuch generally adopts 0.5-0.8mm thin-wall pipe, improve the overall heat transfer performance, under the same heat transfer area, the overall heat transfer coefficient is improved 2-8% than copper tube,

2, stainless steel heat exchange tube is made of high quality stainless steel alloy steel, with strong hardness, so that the hardness of stainless steel heat exchange tube is improved, with impact resistance and vibration resistance,

3. The inner wall of the stainless steel heat exchanger is smooth, so that the thickness of the bottom layer of the boundary layer flow is reduced, and it is not easy to form dirt in the inner wall.

4, stainless steel heat exchanger adopts pressure difference for leakage inspection, no pressure drop in 5 minutes.

Conclusion: in general, copper tube heat in effect than stainless steel tube heat exchange effect is good, but because the stainless steel material is more special, can reduce the wall thickness to shorten and the gap between the brass, and stainless steel tube is not easy to be oxidized, internal won't accumulate dirt, so if it is used for a long time of brass and stainless steel, stainless steel pipe heat for better effect.
