• A cell marked with a (-) represents the ability to bend up to 2.00″ thick. For wall thickness greater than that, contact DMI.
• Figures above represent empirical data and are recommendation only. They do not constitute a warranty.
• All bends are based on the use of DMI mandrels and approved Die Sets.
• For heavy wall pipe special Die Sets may be required.
• Figures shown above are provided as “Average” and will vary depending on the following:

  • Actual wall thickness of the pipe.
  • Actual Yield Stress of the pipe.
  • Skill of the Operators handling the Bending Machine and Mandrel.
  • Origin and Quality of the pipe.
  • Type of Die and Bending Set being used.
