Mandrels

wedge bending mandrels - specification

MANDREL SPECS

  • Mandrels – sizes 6″ thru 60″
  • Pneumatic or Hydraulic
  • are used in conjunction with a hydraulic pipe bending machine to prevent pipe buckling and eliminating ‘out of round’ during the pipe bending process

pneumatic wedge bending mandrels 10-20"

10-20″ Mandrels

10 -20″ PNEUMATIC WEDGE BENDING MANDRELS

  • Prevents buckling and eliminates out of round in the bend
  • Adjustable for any wall thickness within specified mandrel range
  • Self propelled in and out of pipe on models 16” and above
  • Pneumatic wedge mandrels are available in pipe sizes from 10”-20” diameter
  • For efficient operation, the compressed air pressure should be 160-200 PSI (11.0 to 13.8 Bar)
  • Maximum safe working pressure is 225 PSI (15.5 Bar)
  • One man operated for expansion and contracting and for traveling in and out of the pipe on self propelled models
