Is the heat exchanger good with copper pipe? Or is stainless steel better?

I believe that you are more confused, want to know about the knowledge of heat exchanger. Today let Shuangxing stainless steel Xiaobian, detailed analysis for you.

Comparison of the performance of stainless steel heat exchanger tube and copper tube

1, stainless steel heat exchanger has the following advantages:

The heat transfer pipe adopts 0.5-0.8mm thin-walled pipe, which improves the overall heat transfer performance. Under the same heat transfer area, the overall heat transfer coefficient is increased by 2.121-8.408% compared with copper pipe.

Because the material is made of SUS304 high-quality stainless alloy steel, it has a higher hardness, the steel of the pipe is also significantly improved, therefore, it has strong impact resistance and vibration resistance.

Because the inner wall of the pipe is smooth, the thickness of the boundary laminar flow bottom layer is thinned, which not only strengthens the heat transfer, but also improves the anti-scaling performance.

Ø In order to eliminate welding stress, heat treatment is carried out at 1050℃ in protective gas.

Ø Steel pipe is used for leakage check by differential pressure, pressure test to 10MPa, 5 minutes without pressure drop.
