Guangdong Metal Corporation is a professional manufacturer and supplier of Stainless Steel Fin Tube with high quality and reasonable price.
Stainless steel fin tubes are manufactured from a range of seamless and welded plain tubes, utilizing different grades of stainless steel.
Stainless steel fin tube is a heat exchange element. In order to improve the heat exchange efficiency, the outer surface area (or inner surface area) of the heat exchange tube is generally increased by adding fins on the surface of the heat exchange tube, thereby achieving the purpose of improving heat exchange efficiency.Stainless steel fin tube are capable of increasing the output of heat and they also supply uniform heat. Stainless steel fin tubes are used in tube type heat exchange, as they can augment the heat transfer that takes place inside the heat exchange tubing and the outside.

Manufacturing Process of Stainless Steel Pipes/Tubes:
1. Raw Material Selection: The process begins with the careful selection of high-quality stainless steel raw materials. Various grades of stainless steel, such as 304, 316, or duplex stainless steel, are chosen based on the specific requirements of the application.
2. Tube Formation: The selected stainless steel material is initially formed into a tube shape through a primary manufacturing process. This can be achieved through different methods, including hot extrusion, cold drawing, or welding. The choice of method depends on factors like tube dimensions, wall thickness, and desired mechanical properties.
3. Cold Rolling/Cold Drawing: In this stage, the tube undergoes cold rolling or cold drawing processes to refine its dimensions, improve surface finish, and enhance mechanical properties. Cold rolling involves passing the tube through a set of rollers to reduce its diameter and wall thickness, while cold drawing involves pulling the tube through a die to achieve the desired dimensions and surface finish.
4. Heat Treatment: After cold rolling or cold drawing, the stainless steel tube may undergo heat treatment processes to enhance its mechanical properties. This typically involves annealing, where the tube is heated to a specific temperature and then slowly cooled to relieve stresses and improve ductility.
5. Finishing Operations: The tube may undergo various finishing operations, such as polishing, grinding, or buffing, to achieve the desired surface finish. This helps to remove any surface imperfections and improve the aesthetic appearance of the stainless steel tube.
6. Testing and Quality Control: Throughout the manufacturing process, the stainless steel tubes undergo rigorous testing and quality control measures. This includes non-destructive testing methods like ultrasonic testing, eddy current testing, or visual inspection to detect any defects or irregularities.
7. Cutting and Final Inspection: Once the tubes are manufactured and have passed all quality checks, they are cut into desired lengths according to customer specifications. The final inspection ensures that the tubes meet the required standards and specifications before they are ready for packaging and shipment.
Packaging of Stainless Steel Tubes/Pipes:
Please don’t worry that our products are packed, stored, transported according to the international regulation. We do care about the quality of our products; even some little details are paid attention to.
We wrap the stainless steel products with anti-rust paper and steel rings to prevent damage. Identification labels are tagged according to standard specification or customer's instructions. Special packing is available as per customer's requirement.
Plus, our storage racks are made of wood. Other kinds of metals are settled in other places, far from the stainless steel. Any unwanted chemical reaction can be prevented.
