Fretting Damage Analysis and Research on Pipe Thread

Abstract:

The connected pipe thread will be loosed under the pressure impact and vibration effects. Based on the analysis of the sealing mechanism of pipe thread, the essence of the pipe thread loosening is caused by fretting damage and fatigue. The following three methods are used to reduce the damage: the processing requirements of internal and external screw thread tooth type and size will be improved；the deformations which are made by a screwing torque to the external thread of the material itself will fill the gap in each part after internal and external screw thread are screwed together;plasticity sealing filler are put between internal and external screw thread.
