Hydraulic Tube Expansion Machine

  • Drive communicates with the pump via 9v DC remote control. This ensures safety & Eliminates the need of electrical.
  • Compatibility- Same power pack for all 4 drives to expand 5/8" OD to 4" OD tube.
  • Very high Torque developed- can expand large diameter, thick wall tubes in thick tube sheets easily.
  • Boiler erections get completed in record time.
  • Can be use for long working hours because drive is unaffected by heat.
  • Dual drive power pack is available to connect 2 drives to single power pack to cut down tube expansion time by further 50%.
  • Drive speed remains constant during the expansion cycle unlike electric or pneumatic drives.
  • Microprocessor controls on the pump automate the expansion cycle. Trip, pause & reverse times For the drive are adjustable.
  • No need for repeated manual STOP/ START of the drive during Expansion cycle- Complete automatic.
  • The hydraulic pump supplied with hydraulic drive incorporates the latest state of the technology resulting in a subcompact pump developing 100 bar pressure.
  • The system is mounted on four wheels for on site manevourability.
  • Expansion of tubes is regulated by adjusting pressure setting pump Once required amount of wall thinning is achieved the drive trips automatically.
