Study on the Relationship between Fatigue Break of Hydraulic Pipe and Hydraulic Pressure

Based on the analysis of hydraulic pipe break style,the relationship between fatigue break of hydraulic pipe and hydraulic pressure was studied.The result is that,fatigue break is one of the patterns of hydraulic pipe break.The load plumbed with the axes of crooked pipe,the crooked load and draw load along circumference acted on pipe elliptic section is produced by the hydraulic pressure.The load plumbed with the axes of crooked pipe,the crooked load and draw load raise with the hydraulic pressure.The variational load engendered by hydraulic pressure undulation is one of the main factors of hydraulic pipe fatigue break.
