ABSTRACT:
In the on-site manufacture of nipples of relatively short length for joining pipe sections in a conduit system, spacer pins and spacers are selected to achieve a user-determined displacement between an end stop and cutting element of a pipe groover used for cutting external annular grooves along the pipe stock. The use of the spacer pins and spacers allows the grooving tool to be displaced at measured displacements from a selected end of the pipe stock while providing a visual gauge to the user of such displacement.
In the fabrication of these nipples, the end stop/yoke is positioned abutting a selected end of the pipe stock thereby positioning the cutting element where a first groove is cut. Upon selection of a combination of spacer pins and/or spacers the end stop is again positioned to abut the selected end of the pipe stock thereby positioning the cutting element where a second groove is cut. Finally upon the selection of a subsequent combination of spacer pins and/or spacers the end stop is positioned to abut the selected end of the pipe stock thereby positioning the cutting element where a third groove is cut. This third groove defines the length of the nipple once separated from the pipe stock.
