Upon examination of a fracture burst, it was found out that the main reason for this is the fatigue of the material in the annular section of the pipes. Analysis was made of the stress state and its impact on the nature of the destruction. In a working conditions, especially in rotor drilling, a direct correlation between the loss of stability of the column in the compression zone and the destruction of drill piping due to fatigue failures in material is established. Object of study is the nature of the destruction of defective drill pipe


Keywords – drilling pipes, fatigue demolition, defects
