Analysis of the causes of remanence caused by directional drill pipes The reasons for remanence caused by directional drill pipes are as follows:(1) metal melting or pipeline manufacturing process;(2) The pipeline is stopped in a strong magnetic field;(3) Non-destructive testing by magnetization method;(4) Preheating the weld joint by electromagnetic induction method and heat treatment to produce remanence;(5) Cutting lathe grinding wheel grinding groove;(6) The axis is consistent with the direction of the geomagnetic field and is magnetized by the geomagnetic field due to impact or vibration.

Causes of Remanence of Directional Drill PipeAnalysis
The reasons for the remanence of the directional drill pipe are as follows:
(1) metal smelting or pipeline manufacturing process;
(2) The pipeline is stopped in a strong magnetic field;
(3) Nondestructive testing by magnetization method;
(4) the use of electromagnetic induction method to preheat the weld, heat treatment generated by the residual magnetic;
(5) Lathe cutting cargo grinding wheel grinding groove;
(6) The axis is consistent with the direction of the geomagnetic field and is magnetized by the geomagnetic field due to impact or vibration.
