Hydraulic Upsetting Machine

A hydraulic upsetting machine is a specialized forging or forming machine used to increase the diameter (upset) of the end of a pipe, tube, rod, or bar through axial compression, typically by applying high-pressure hydraulic force. It's commonly used in industries such as oil & gas, construction, and mechanical manufacturing—especially in drill pipe production, tool joints, and high-pressure pipe ends.

What it Does:

The hydraulic upsetting machine enlarges the diameter of the end of a tube or rod by applying axial hydraulic force while holding the workpiece in a fixed die. This process is known as "upsetting" and is used to:

Prepare pipe ends for threading or connection (e.g., API tool joints)

Strengthen the joint section for higher mechanical load resistance

Ensure dimensional precision before further machining

• Hydraulic Clamping & Centering: Ensures firm, automatic grip of the pipe or rod during upsetting

• Servo-Controlled Upsetting Stroke: Precise control of upsetting distance and force

• Induction or Gas Heating System: Optional preheating of the pipe end before upsetting

• Interchangeable Die Sets: For handling multiple pipe diameters and lengths

• PLC Control System: Allows preset of stroke, force, timing, and production records

Pipe Applications:

• Oil & Gas: Drill pipes, casing pipes, API tool joints

• Mechanical Engineering: Forged shafts, rods, connecting components

• Pressure Pipe Manufacturing: Ends for couplings or flanges

• Pipeline Fabrication: High-strength end forming for heavy-duty pipes
