Carbon Steel HF serrated Finned Tube
HF welded spiral finned tube is the most widely used of the spiral finned tube, widely used in electric power, metallurgy, cement industry preheating collection and petrochemical industries. High-frequency spiral finned tube is welded steel strip coil pipe at the same time, using high-frequency currents of the skin effect andproximity effect of steel tube, and surface heat until melted in the plastic state or steel strip coil, the complete welding under certain pressure. This kind of high frequency welding as a solidphase welding. It with Mosaic, brazing (or whole galvanized) method, whether in product quality (fin of weld rate is high, of 95%), or the productivity and automation degree, are more advanced.
