Drill Pipe Upsetting Production Line

The drill pipe upsetting production line is engineered for the end-upsetting (thickening) of oil and gas drilling pipe bodies, combining induction heating with hydraulic upsetting forging to locally heat each pipe end and apply controlled axial compression, producing plastic deformation that increases the wall thickness in the upset zone — meeting the stringent high-strength and fatigue-life requirements of drill pipe tool joint connections under demanding downhole conditions.
The core heating unit employs medium-frequency induction technology for fast, precisely targeted localized heating of the pipe ends. Rapid temperature ramp-up, uniform heat distribution, and a heat-affected zone strictly confined to the upset area prevent performance degradation in the pipe body beyond the forming zone, ensuring the workpiece undergoes upsetting within the optimal temperature window.
The hydraulic upsetting mechanism delivers high-tonnage, smooth, and precisely controlled axial force in conjunction with high-rigidity forming dies, completing the full upset profile in a single stroke. The resulting thickened zone exhibits accurate wall thickness dimensions, regular geometry, and good inner and outer surface quality — meeting API and other petroleum industry standards for drill pipe end upset dimensions and tolerances.
A closed-loop temperature detection and control system monitors the heating temperature of the upset zone in real time, precisely preventing overheating and overburning, and ensuring consistent upsetting process parameters for every pipe — guaranteeing uniform forming quality and microstructure across the entire production batch.
With a high degree of overall automation, the line integrates loading, induction heating, hydraulic upsetting, and unloading in a smoothly sequenced workflow with stable cycle times. It supports internal upset, external upset, and internal-external combined upset process modes, with flexible accommodation of different pipe outer diameters, wall thicknesses, and steel grades, and convenient specification changeover.
