俄罗斯用于管道焊缝热处理的感应加热设备ТВЧ具有良好的技术经济指标。它的主要优点是能够按照相应标准自动维持热处理规范、操作简单及可同时处理几根较小直径管的焊接接头 ,从而有较高的生产率。设备所需的功率 ,可以按公式计算 :P=Aδ( D- δ) n,k W式中　 A—综合系数 , Russia ТВЧ induction heating equipment for heat treatment of pipe welds has good technical and economic indicators. Its main advantage is the ability to automatically maintain heat treatment specifications according to the appropriate standards, simple operation and the ability to handle several smaller diameter pipe welded joints at the same time, resulting in higher productivity. The required power of the device can be calculated as: P = Aδ (D-δ) n, k W where A is the synthesis factor,
