By the process, output power is reduced; welding speed is increased; the weld joint quality of the steel pipe can be guaranteed better; the energy-saving and emission-reducing policy advocated at present is followed; and finally the pipeline can be adapted to normal operation under the low-...
一、“HFW”含义 “HFW”是“High Frequency Welding”的缩写,即高频直缝电阻焊钢管。 高频直缝电阻焊是一种焊接工艺,利用高频电流的集肤效应和邻近效应,使待焊接的边缘迅速加热至熔化状态,然后在挤压辊的作用下实现焊接。这种焊接方法具有焊接速度快、生产效率高、焊缝质量稳定等优点。主要用于生产中小口径的钢管,广泛...
一样的产品，一样的制造工艺，只是缩写不一样，英文全称：High Frequency （高频）Electric Resistance （电阻）Welding（焊接），中文全称：高频电阻焊管，因为只有直缝才能焊接出这种类型，所以也叫（直缝高频电阻焊钢管、高频直缝钢管、高频直缝焊管、高频焊直缝钢管 、高频直缝电阻焊钢管等等），只是英文缩...
