消磁钢管经过加工和探伤后会残留磁场，直接影响加工和使用，所以必须要进行退磁。消磁钢管表面的磁场性质和消磁钢管特定的环境有很大关系，不是所有的磁场都是一个特性，分直流磁场、交流磁场、不规则磁场等，必须要针对磁场特性选择不同退磁方法，直流一般要选用直流专用退磁，交流选择交流退磁方法，我们为您提供各种不同的退磁设备。

Parts will remain magnetic field after processing and flaw detection, directly affecting processing and use, so demagnetization is necessary. The nature of the magnetic field on the surface of the workpiece has a great relationship with the specific environment of the workpiece. Not all magnetic fields are a characteristic. They are divided into direct current magnetic field, alternating current magnetic field and irregular magnetic field. Different demagnetization methods must be selected according to the characteristics of the magnetic field. Direct current usually uses direct current special demagnetization method, alternating current demagnetization method. We provide you with various demagnetization equipment.
