flow control technology

HD test bladder and HD flow control bladder for leak tests


By one inspection chamber section leak test or pipe sleeve test pressure is possible.

  • test bladder and flow control bladder in one work step
  • small cross-section
  • durable and solid, technology based on the HD Packer
  • equal operation pressure of test bladder and flow control bladder
  • quick and easy exchange of valves and seals

When using multidimensional block off bladders (small cross-section / large expand-volume as dimension 50-150) or our new HD test bladder together leak tests can now be realized,as easiliy as ever before. In addition, branched drainage systems can be implemented with multiple dimension jumps in the smallest dimension to verify the largest dimension in sections or at points for leaks.
