Abstract:
The physical simulation results on Gleeble-3800 of the individual stages production of large diameter pipes are presented and the effect of these stages on the final properties of the pipe material was investigated. Using «tension-compression» method for the physical simulation on Gleeble-3800 the stretching temperature effect on mechanical properties formation of large diameter pipes was investigated at each stage pipes redivision: molding, expansion and polymer coating thermal cycle.
