H-Expander
H-Expander is an innovative hydraulic rerounding device. It is used in partially collapsed pipes when more than 10% deformation would have required replacement before relining. This tool pushes collapsing sections back to full roundness. It leaves behind a stainless steel sleeve to support the pipe pieces until relining takes place.
  • One tool covers 8, 10 and 12 in. pipes
  • More than 70,000 lb. lift capacity
  • Separate nose cone circuit opens the way for the main tool
  • Can enter sections collapsed more than 25%
  • Installs a 2 ft. ratchet locked sleeve
  • Extra sleeves can be added together
  • Controlled expansion ensures circular result
  • 250 ft. reach from point of entry
