Bellows are commonly used heat exchange tubes in thermal equipment. Due to the performance characteristics of non embroidered steel corrugated pipes, they are increasingly being used. Let's take a look at the characteristics of non embroidered steel corrugated pipes, which are widely used!
1. Non embroidered steel corrugated pipes have high thermal conductivity.
The heat conduction enhancement of corrugated tube heat exchangers is based on their unique ultra thick walled corrugated tubes, which are continuously laser cut with large diagonal and small curved lines. The internal structure of the thick walled tubes looks like corrugated tubes. The slope between the corrugated pipes will significantly affect the liquid. The influence of the internal structure of the corrugated tube comes from the hazards of liquid exercise inside and outside the pipeline, so the level of impact is stronger and more complete. Even if the liquid velocity is very low, it can still enter a neutral state. The temperature field of the thick wall of the corrugated tube heat exchanger is relatively small, which can reduce the heat transfer coefficient of the wall thickness, improve the thermal conductivity inside and outside the pipeline, and enhance the overall thermal conductivity.
2. Non embroidered steel corrugated pipes can withstand excessive temperature differences.
The wall thickness of the corrugated pipe is only 0.5-0.8mm, which can be said to be very thin because of its unique arc shape and forming production process, which further improves its ability to withstand pressure work. The single-sided rupture working pressure of the corrugated tube measured in the laboratory is generally around 20mpa. In specific applications, adjusting the working pressure below 6.4mpa is reliable. The corrugated tube heat exchanger commonly used by people is made of stainless steel plate, which can be integrated into high operating temperatures (up to 450 ° C). In addition, corrugated tube is a flexible component with certain thermal compensation capabilities, and has good adaptability to industrial equipment with large temperature differences and low internal stress during operation. Compared with general pipelines, it has obvious advantages.
3. Non embroidered steel corrugated pipe with complete scale cleaning function.
The stainless steel corrugated tubes of the corrugated tube heat exchanger are made of high-quality stainless steel, which is corrosion-resistant. More importantly, the unique inner and outer wave patterns of the corrugated tubes are continuously washed away by intermediate substances, and the inner and outer layers of the heat exchanger tubes are not prone to dust deposition. The refractive index of each part of the corrugated pipe constantly changes, so the linear expansion index difference between metal corrugated pipes and stains is quite large. When pollutants are caused, the stains and the surface of the corrugated pipe provide support, reducing the amount of stains and ensuring fully automatic cleaning and scale cleaning. This type is unparalleled by other heat pipe replacements.
4. Stains have strong corrosion resistance.
Because there is no forced deformation during the entire forming process, it is not easy to cause stress, and the internal stress distribution is uniform without intergranular problems. Therefore, it is not easy to cause stress during the entire forming process, and the internal stress distribution is uniform without intergranular problems. Therefore, it has strong resistance to intergranular corrosion.
