HW6 Hand expander machine

The hand expander machine HW6 serves to expand the ends of thin-walled metal pipes. Thus it is possible to provide chimney pipes, ventilation or rainfall pipes etc. with sleeves for a joint connection, stationary or at the building site.

The special advantages are as follows:

  • the fact that in case of using high-grade steel flexible pipes, it is easily possible to widen standard connecting pieces afterwards,
  • the fact that remaining parts of pipes can be used as fit parts by means of expanding a sleeve,
  • the fact that connecting pieces can be manufactured by yourself for various diameters,
  • the fact that pipes can be adapted for heating connections,
  • the fact that a further visit to the building site can be omitted in most cases,
  • that we supply each expansion tool that you can imagine at short notice, at reasonable prices, according to your requirements,
  • low cost ensures quick time of machine.
  • that the tools are compatible to our hydraulic production machines,
  • that the machine incorporates a scale with a diameter related mm-divisions (the sleeve diameter can be reproduced exactly),
  • that the machine – running with trapezium thread spindle / bronze nut drive and bronze segments on hardened and precisely polished spreading bolt - is designed for a long life,
  • that due to the divisible rack the machine can be transported in any car.
