I. What are Stainless Steel Finned Tubes?
Stainless steel finned tubes are primarily manufactured using 304 or 316 stainless steel tubing. They possess numerous significant advantages: aesthetic appeal, high strength, low flow loss, strong corrosion resistance, resistance to deformation under prolonged hot and cold conditions, and a long service life.
Stainless steel finned tubes utilize water, steam, or heat transfer oil for heating, employing a low-temperature heating method that can maintain a constant indoor temperature for extended periods. This has made them a popular and superior heat dissipation device for large-area applications in recent years.
For example, in the manufacturing process, 304 or 316 stainless steel tubing is primarily used. Not only is it aesthetically pleasing, but it also possesses strong corrosion resistance, ensuring stable operation even in complex environments.
Its high strength and low flow loss effectively guarantee heating performance. Furthermore, its resistance to deformation under prolonged hot and cold conditions significantly extends its service life.
Stainless steel finned tubes require regular maintenance and upkeep after a period of use. Check for coking, deposits, and rust layers inside the equipment; regular cleaning can extend their service life.
There are different types of stainless steel finned tubes. For example, stainless steel high-frequency welded finned tubes typically use stainless steel tubes with a diameter of 10-219mm, then weld steel strips to the surface of the tube using high-frequency welding. These have a high heat transfer coefficient, thicker fins, and are more robust than other finned tubes, resulting in a longer service life and better performance.
Stainless steel aluminum finned tubes use a stainless steel base tube encased in an aluminum tube, which is extruded to form fins. The fin base is tightly fitted to the outer wall of the tube, resulting in a high heat transfer coefficient, excellent heat transfer performance, and strong corrosion resistance.
Stainless steel finned tubes also include stainless steel wound finned tubes, made of high-quality stainless steel, which have excellent corrosion resistance and high-temperature resistance. Their unique wound fin design significantly increases the heat transfer area and improves heat exchange efficiency.
Because the outer surface of the finned tubes is smooth, it is not prone to scaling, making it easy to clean and maintain, thus extending the service life of the equipment. Stainless steel finned tubes, as a heat exchange element, have fins added to their surface to increase heat exchange efficiency, thus increasing the external surface area and improving efficiency. This product is made from seamless steel using a special welding process and uses water, steam, or thermal oil for heating.
Stainless steel finned tubes are aesthetically pleasing and possess superior corrosion resistance. Compared to other finned tubes, stainless steel finned tubes have a service life at least three times longer.
