2. A aluminum cooling tube finned is formed by high frequency welding, the base tube and fin rotating on the official surface by a high-frequency welding process.
3. High-frequency resistance welding spiral finned tube is to introduce high-power high-frequency current into the welded part, and use the resistance heat generated by the current passing through the contact surface of the welded part joint and the adjacent area to make the welding contact surface reach melting or semi-melting plasticity State, and then apply appropriate pressure to the welding contact surface to complete the welding work of the finned tube.
4. Advantage: High production efficiency, good heat transfer performance
5. Package: The aluminum finned tubes are packed in wooden cases.
6. QUALITY CONTROL:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking.
