Pipe end calibration: Precision for perfect weld seams.

At AWS Schäfer, we focus on individual solutions. If standard machines are not sufficient, we offer custom-made products and retrofit solutions that are precisely tailored to your requirements.

One example: Our pipe end calibration technology ensures that ovality on pipe bends, T-pieces or straight pipes is eliminated by precise round calibration to guarantee perfect weld seams - reliably, efficiently and tailor-made.

AWS pipe end expander:

  • Hydraulically operated machine
  • Calibrates the pipe end from the inside over the entire circumference of the pipe end
  • Circular calibration of the pipe end

Combined AWS pipe end calibration machine:

  • Hydraulically operated machine
  • Pipe end is first expanded from the inside
  • Then calibrated to the required outside diameter
  • High roundness tolerances
