ST 225

ST225 is a pipe compressing tool for the arrest of flow in Polyethylene pipes for gas and water with diameters up to 225 mm - 9”, the tool is of the latest generation and do not have the typical limits of the similar old type tools that use simple “bottle type jacks”. Thanks to its exclusive characteristics assures the best results and cannot miss today in the equipment of the modern utilities underground pipes maintenance crews.

Benefits of use

  • Robust hydraulic double effect cylinder with long rod guide designed to avoid deformation of the rod when in total extension (typical defect of the traditional tools with bottle type jacks)
  • High quality separate hydraulic pump, separated pump from tool means stability, tool remain firm on the pipe when pumping so there is not the typical rocking movement possible with the traditional tools , separated give also the possibility to work with tool in any position.
  • Supplied with two series of spacers for SDR 11 and SDR17 needed to avoid over compression of pipe.
  • The effort needed to pump is minimal thanks to the pump type and to the large cylinder.
  • The high power guarantees total compression also on larger pipe diameters and also in winter when the polymer is very hard.
  • Ideal compression quality as ST225 allows a slow re opening of the jaws after the compression, the pipe is more subject to damage in the reopening action then during compression, traditional tools can only allow a fast re opining that can cause the phenomenon called “entanglement” of the PE fibres, the molecules of the polymer when are rapidly released after compression do not return “in order” at their original position and this often can create a point of weakness in the PE structure with consequent probable rupture of the pipe, ST225 is free of this possibility.
  • Supplied in strong wood box with locks for the care and transport
