• 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.

• Normal unbend tangent for PBM 6-20 is 5′
• Normal unbend tangent for PBM 16-30 is 6′
• Normal unbend tangent for PBM 22-36 is 6′
• Normal unbend tangent for PBM 32-42 is 7′
• Normal unbend tangent for PBM 48-60 is:

  • 11′ for Stiffback end with pipe support
  • 13′ for Stiffback end with NO pipe support
  • 8′ for Pinup end with pipe support
  • 9′ for Pinup end with NO pipe support
