ERW steel pipe/tube making machine
The steel plates in certain width after slitting and stripping are unfolded and leveled and then sent into a forming machine. By using the roller, the steel pipe is processed into pipe state. The edge of the steel plate is melted by the proximity effect and skin effect of high frequency current. Then the plate is extruded and welded into pipes by using extruding roller. High Frequency steel Pipe Mill is also called ERW (electric resistance welding) pipe mill. Application 1.High Frequency steel Pipe Mill is suitable for all kinds of round pipe, square pipe and rectangular pipe. 2. According to the product functions, welded pipe making machine is divided into API model and national standard model. API model mainly produces high level steel pipes such as delivery pipe of petroleum, natural gas and oil well casing. National standard model mainly produces the steel pipe, such as water-gas pipe and structure pipe.
Advantages 1. In the preparation process, High Frequency steel Pipe Mill mainly developed the volume type loop hoppers. 2. In the aspect of forming unit, this welded pipe making machine developed double wire forming. 3. The structure of forming unit developed part of the vertical roll group, the small row roller straight shape and vertical roll shape.
