High-frequency welding spiral finned tube, is the use of high-frequency current characteristics, the product of the metal strip on the metal pipe weld formation. Because of finned tube heat transfer area has a large, high efficiency heat transfer, so the gas furnace, oil furnace and radiator mix, its overall heat transfer performance was significantly better than the same size, the same material ordinary tubes, Studded tube. With finned tubes as the core element of a variety of heat transfer equipment, electricity, chemicals, shipbuilding, civil building, oil refining unit has been more widely used L-type (square) finned tubes (fin tube) Specifications : φ32 * 4 φ32 * 5 φ38 * 4 φ38 * 5 φ42 * 5 φ48 * 5 φ51 * 5 φ51 * 6, etc. We can produce diameter: φ25 ~ φ65, wall thickness greater than 3mm; L-type (square) wings Tube (fin tube) material: carbon steel, stainless steel, ND steel, alloy steel. Spiral finned tubes (fin tube) Specifications: φ16 ~ φ106, wall thickness greater than 2mm; spiral finned tubes (fin tube) material: carbon steel, stainless steel, ND steel, alloy steel. Can be customized according to user specific requirements, we can also help customers design.
