ABSTRACT:
A ring member having an opening extending radially therethrough to provide access between the inside and outside of said ring member. The ring member is disposed between the ends of two adjacent pipe sections, and is in sealing engagement therewith.
The opening in the ring member provides mounting means for a pressure gage, or an access fitting to the pipeline to add dye materials or other reagents. The adjacent pipe sections may be rotated to equalize wear without rotating the ring member so that the pressure gage may be maintained on the top of the pipeline for ready access.
