Bellows are the most commonly used heat exchangers in thermal equipment. Because of the performance characteristics of Stainless Steel Flexible Hose, stainless steel corrugated pipes are used more and more.

1. The stainless steel corrugated pipe has high thermal conductivity.

The heat transfer enhancement of the bellows heat exchanger is based on its unique ultra-thick-wall bellows, continuous laser cutting of large oblique lines and small arcs, and the internal structure of the thick-walled tube looks like a bellows. The slope of the bellows and the middle of the bellows will significantly affect the liquid. The influence of the internal structure of the bellows comes from the harm of the fluid fitness movement inside and outside the pipeline, so the level of influence is stronger and more complete. Even if the liquid velocity is low, low, it can go into a neutral condition. The temperature field of the thick wall of the bellows heat exchanger is small, which can reduce the heat transfer coefficient of the wall thickness, improve the thermal conductivity inside and outside the pipeline, and improve the overall thermal conductivity.

2. The stainless steel corrugated pipe can bear excessive temperature difference.

The wall thickness of the bellows is only 0.5-0.8mm, which can be said to be very thin. Because of the distinctive arc shape and forming production process of the bellows, the working capacity under pressure is further improved. The unilateral rupture working pressure of the bellows measured by the laboratory is generally around 20mpa. In specific applications, it is reliable to adjust the working pressure below 6.4mpa. The commonly used bellows heat exchangers are made of stainless steel sheet, which can be integrated into higher operating temperatures (up to 450°C). In addition, the bellows is a soft component with a certain thermal compensation ability, and has a good adaptability to industrial equipment with relatively large temperature differences and low internal stress during operation. Compared with the general pipeline, it has obvious advantages.

3. Stainless steel bellows, complete scale cleaning function.

The stainless steel bellows of the bellows heat exchanger is made of high-quality stainless steel, which is resistant to corrosion. More importantly, the distinctive inner and outer wave patterns of the bellows are continuously washed by the neutral substance. The outer layer is not easy to deposit dust. The refractive index of each part of the bellows is constantly changing, so the linear telescopic index of the metal bellows and the stains is quite different. When pollutants are formed, the stains and the surface of the bellows will cause supporting force, and the stains can be reduced, so as to ensure fully automatic Cleaning, automatic scale cleaning. These are all unmatched by other heat exchangers.

4. The stain has strong corrosion resistance.

Because there is no forced deformation in the whole forming process, it is not easy to cause stress in the whole forming process, and the internal stress distribution is uniform without intergranular problems, so it is not easy to cause stress in the whole forming process, and the internal stress distribution is uniform and there will be no crystals. Therefore, it has a strong ability to resist intergranular corrosion.
