First, cold rolled steel and aluminum finned tubes Overview: cold rolled steel and aluminum finned tube before it is processed by processing aluminum and steel double metal composite pipe water heating finned radiator, and then by mechanical rolling, the use of aluminum physical characteristics, made with a core of steel tube and cold rolled aluminum fins closely integrated as one of the finned tube. Second, cold rolled steel and aluminum finned tube Features: 1. High performance finned heat sink, the thermal contact resistance is small; 2. fins and tubes large contact area, tight fitting, solid; 3. Good corrosion resistance Long-term use of stable performance; 4. maximum use temperature ≤300 ° C; 5. Maximum operating pressure ≤3.2MPa; one piece of steel and aluminum winding finned tubes Overview: steel sheet aluminum finned tube around the use of advanced automation and control equipment The tightly wound aluminum outer steel wall, an L-shaped finned radiator factory equipment to ensure clean air supply air. Widely used in petroleum, chemical industry, cold water heat exchanger, hot water radiator. Second, steel and aluminum winding sheet finned tube Features: 1. base tube is not in direct contact with the air, no rust, corrosion; 2. Efficient thermal performance, enabling rapid and uniform heat transfer into the air; 3. Aluminum Pipe Operating temperature around the chip finned tube: 230 ℃.
