The application advantages of 316L stainless steel heat exchange tubes are attributed to the addition of Mo element, which provides corrosion resistance, atmospheric corrosion resistance, and high-temperature strength. This allows for use under harsh conditions.
Additionally, 316 stainless steel exhibits work hardening (non-magnetic), good high-temperature strength, non-magnetism in a solid solution state, and cold rolled products with a pleasing appearance gloss. As a result of these properties, it is widely utilized in heat exchangers within petrochemical, pharmaceutical, food, and other industries.
Based on production process characteristics and appearance attributes, 316 welded stainless steel heat exchange tubes can be categorized into five types.
1. The straight tube heat exchange tube is a commonly used type, known for its simple structure and easy production, making it suitable for all types of heat exchangers.
2. The bellows heat exchange tube features a corrugated surface to increase fluid turbulence and enhance heat exchange efficiency, making it ideal for gas-based shell-side fluid in heat exchangers.
3. Spiral heat exchange tubes have a spiral outer surface to boost fluid turbulence and improve heat exchange efficiency, making them suitable for gas-based shell-side fluid in heat exchangers.
4. Welded heat exchange tubes are connected by welding, offering high strength, sealing performance, and cost advantages. They are suitable for high-temperature and high-pressure heat exchangers.
5. Expansion heat exchange tubes are connected by expansion, providing good sealing performance and easy disassembly. They are suitable for low-temperature and low-pressure heat exchangers.
When choosing the 316L stainless steel heat exchange tube, it is important to consider the following factors:
1. Fluid properties: Select a heat exchange tube with appropriate corrosion and oxidation resistance based on the fluid's characteristics.
2. Working temperature and pressure: Choose a heat exchange tube with suitable strength and stability according to the required working temperature and pressure.
3. Equipment structure and installation requirements: Select the appropriate connection method and manufacturing process of the heat exchange tube type based on equipment structure and installation needs.
In summary, the various types of 316 stainless steel heat exchange tubes include straight, corrugated, spiral, welded, and expansion tubes. When choosing the appropriate type of 316 stainless steel heat exchange tube, it is important to consider factors such as fluid properties, operating temperature and pressure, equipment structure, and installation requirements in order to ensure reliable operation and equipment safety.
