PGNM Gouging Nozzle
PGNM nozzles employ the nozzle mix principle for gouging, in application the nozzle cuts a “U” shaped groove in the plate or weld material. Designed to be used with NM type cutters or heavy duty cutting attachments.
The use of oxy- propane allows for high speed cost effective production.
The most common use is to “back gouge” butt welds to remove any defects prior to laying the final sealing run.
They also find application in the removal of defective welds or flaws in steel plates.
There are 4 models in the range each providing a “U” groove of different dimensions.
