fine copper heat exchanger

Misunderstanding 3: No welding seam or smooth inner wall is not afraid of corrosion? 　　No welding seam or smooth inner wall does not mean that there is no corrosion. I hope our introduction can be helpful to you.. In recent years, due to the continuous improvement of the heat exchanger manufacturing process, the industry requirements have become higher and higher. This kind of coating mainly achieves anti-corrosion by isolating and preventing water from directly contacting the substrate.　　

The coating and the substrate are chemically bonded at high temperature, with strong adhesion and not easy to peel off. Therefore, many heat exchangers with internal coating on the market fine copper heat exchanger have large areas of blistering after being soaked in hot water for about 5 days, the coating begins to peel off, and the substrate rusts. And anti-corrosion is the highlight of the heat exchanger market this year. However, the coating and the body are glued together (physical bonding), which requires high surface treatment of the substrate, otherwise the coating is likely to peel off, which is a defect of organic coatings. For example, if there is silt, excessive sulfur content in the system, or the copper surface is selected with carbon Etc.

Consumers should be cautious when choosing anti-corrosion heat exchangers. In addition, experts remind consumers: Because aluminum alloy heat exchangers have different water quality requirements from steel, avoid mixing aluminum alloy heat exchangers with other materials. The above is the introduction of our plate heat exchanger manufacturer's customer service about the five major mistakes in the purchase of spiral plate heat exchangers.

Generally speaking, copper has better corrosion resistance than steel, but under certain circumstances, copper heat exchangers will also corrode. When the heating is stopped, they must be filled with water and sealed to prevent air from entering; while aluminum ones are afraid of alkaline water corrosion.　　 Misunderstanding 1: Is the wall thickness afraid of corrosion? 　　 Cast iron heat exchangers are not easily damaged by corrosion because the cast iron itself has good oxidation and corrosion resistance, not because of the wall thickness. will cause corrosion of the copper heat exchanger
