Stainless steel heat exchange tubes have the following advantages:
1. The heat exchange tube adopts 0.5-0.8mm thin-walled pipe to improve the overall heat transfer performance. Under the same heat exchange area, the overall heat transfer coefficient is 2.121-8.408% higher than that of the copper pipe.
2. Because the material is made of SUS304 high-quality stainless alloy steel, it has high hardness and the steel of the pipe is also obviously improved. Therefore, it has strong impact resistance and vibration resistance.
3. Due to the smooth inner wall of the pipe, the thickness of the bottom layer of the boundary laminar flow is reduced, which not only enhances heat exchange but also improves anti-fouling performance. In order to eliminate the welding stress, heat treatment is performed at a high temperature of 1050 ° C in the shielding gas. The steel pipes are all subjected to leakage inspection using a pressure difference, and the air pressure test is 10 MPa, and there is no pressure drop for 5 minutes.
