Equivalent Stress Analysis of Processing Tube Tension-Reducing of the New Steel 33Mn2V for Oil Well Tubes

Finite element method (FEM) is used for simulation of two-pass processing tube tension-reducing of the new steel 33Mn2V for oil well tubes. The simulated results visualise dynamic evolution of equivalent stress, especially inside the work-piece. It is shown that the non-uniform distribution of equivalent stress on the longitudinal and transverse sections is a distinct characteristic of the processing tube tension-reducing, which can be used as basic data for improving tool and technics design, predicting and controlling the micro-structural evolution for manufacturing oil well tubes.
