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.

Hydraulic Upsetting Machine – Product Description

 

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

  •  
Key Features of Equipment
 
  • 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

  • Servo-Controlled Upsetting Stroke

Hydraulic upsetter machine FAQs

Do I need heating before upsetting?

For thick-wall pipes or large diameters, yes. Heating reduces forming force and improves material plasticity.

Can one machine handle multiple pipe sizes?

Yes, by changing die sets and adjusting stroke/pressure settings.

Is upset forging better than welding joints?

Yes, upsetting strengthens the material without introducing welding heat-affected zones or metallurgical defects.
