Spiral heat exchanger - high efficiency stainless steel

304/316L stainless steel can resist corrosion from sulfides in sulfur-containing crude oil, preventing equipment damage; at the same time, the spiral flow channel can reduce the deposition of impurities in crude oil, lower the risk of blockage, and ensure a continuous and stable refining process.

efficiency is improved by 20%-30% because the spiral flow channel prolongs the medium contact time and can form turbulence, reducing the heat transfer temperature difference and lowering the energy consumption cost in the crude oil refining process.

Its compact structure is suitable for the limited engine room space of ships, saving installation space; at the same time, it has good vibration resistance and can adapt to the turbulent environment during ship navigation, ensuring the stable operation of the heat exchange system.

It boasts high heat transfer efficiency, enabling rapid absorption and release of heat and timely response to temperature fluctuations during fermentation; furthermore, its uniform flow channels prevent localized temperature deviations, providing a stable environment for microbial growth.​

Stainless steel's high-temperature resistance can handle the high-temperature processes of silicon purification (some steps exceed 500℃), while its precise temperature control can ensure the purity of silicon and reduce the generation of impurities, meeting the high-purity requirements of the photovoltaic industry.​

Its small size allows it to fit into the limited installation space of a computer room, reducing site occupancy costs; it also has strong resistance to scale buildup, minimizing the decrease in heat exchange efficiency caused by scale buildup and extending equipment maintenance cycles.

It could also be due to blockage of the internal flow channels of the heat exchanger (such as accumulation of impurities), aging of seals leading to media leakage, or an imbalance in the flow ratio of hot and cold media. Specific inspection and maintenance are required.

In the routine maintenance of heat exchangers, besides regularly cleaning the scale, what simple methods can be used to check the corrosion resistance of the material?​
