Hydraulic Tube Expanding Machine (Hydex)

Drive communicates with the pump via 9v DC remote control. This ensures safety and eliminates the need of electrical cord between pump and drive that other manufacturers provide.

Silent during use. In comparison electric and pneumatic tube expansion systems are noisy.

Compact, therfore easy to use inside boiler drums.

Compatibility - Same powerpack for all the 4 drives to expand 5/8" o.d. to 4" o.d. tube.

Very High Torque Developed - can expand large diameter, thick wall tubes in thick tube sheets easily.

Long life + low maintenance.

Boiler erections get completed in record time.

Can be use for long working hours because drive is unaffected by heat.

Dual drive powerpack is available to connect 2 drives to a single powerpack to cut down tube expansion time cycle by a further 50%.

Microprocessor controls on the pump automate the expansion cycle. Trip, pause and reverse times for the drive are adjustable. No need for repeated manual STOP / START of the drive during the expansion cycle - completely automatic.

The Hydraulic pump supplied with hydraulic drive incorporates the latest state of the art trechnology 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 on pump. Once required amount of wall thinning is achieved the drive trips automatically.
