Quality that meets even the most demanding requirements

This is probably the most unconventional way to lay ductile iron pipes.

A pipe with VRS®-T joints and ZMU-Austria coating is drawn into the water, which automatically stretches and seals the joints. The cement lining withstands all attacks from the water bed, which consists mainly of mud.

Depending on weight and volume, ductile iron pipes can float independently and sink when fully filled.

  • Up to and including DN 200, depending on the wall thickness, additional floating bodies may be required to keep the pipe above water. From DN 250 and above, the pipe can float independently.
  • Due to unforeseeable loads resulting from wave motion, lowering, subsurface conditions and subsequent subsurface movements, only pipes with VRS®-T restrained joints should be used for floating.
  • It is not necessary to fix the pipe to the water bed.
