Skids & Centralizers



Skids & Centralizers play a critical role in maintaining nozzle position within a pipe. As pipe diameters increase, skids elevate and position nozzlde closer to the center of the pipe for more even pipe wall cleaning. Skids are designed and manufactured  to be smaller thsan the pipe to be used in.  This equalizes the distances from the nozzle orifices to all parts of the pipe wall, more effectively cleaning the crown of the pipe.

Skids combined with the use of Rotary Chain Flail nozzles maintains the chain flail close to the center of the pipe and reduces drag on the bearing of the Rotary Chain Flail. Skids help to reduce the wobbling effects created when debris becomes entangeled within the chain to cause an unbalanced (wobbling) spinning effect. on the nozzle. 

Skids passing through or if prevented from passing through a pipeline can indicate the presence of collapsed pipe or some other type of obstruction. 

All skids require the use of an appropriate length Drain Jet Exension to be used correctly. When properly installed through the center of the skid, the Drain Jet Extension allows for a minimal amount of sliding slack movement. This small amount of slack will allow for a hammering action to free a wedged or stuck skid in a pipe.
