WPB reducer

WPB reducer is also called reducer, which is divided into concentric reducer and eccentric reducer

WPB reducer is a kind of reducer widely used. It can be divided into low carbon steel reducer and medium carbon steel reducer according to material

WPB reducer can also be divided into ordinary low carbon steel, excellent low carbon steel, low carbon boiler steel and low carbon vessel steel. Due to the low carbon content and good weldability of such reducers, excellent welding joints can be obtained without special process measures. Not only that, the low carbon steel reducer has good plasticity, small quenching tendency, and it is not easy to produce cold cracks near the weld seam. Generally, preheating is not required before welding, but it is required to preheat to about 150 ℃ for welding with large thickness or at low temperature

As the carbon content of medium carbon steel reducer is mainly based on the clinical effect, its welding performance is better than that of low carbon steel reducer
