The major emphasis of this paper will concern itself with copper piping because of its universal application and copper vessels have carried water since the time of the Egyptian dynasties. Hard drawn domestic copper pipe is manufactured in 3 types (based on wall thickness ) that is #R-88 Ring Joint CouplingThe ring joint coupling can be installed 3 - 4 times faster than a comparable welded or flanged joint . The processing of a roll groove on pipe becomes more difficult as the pipe O.D. and wall thickness increases. Roll grooving pipe larger than 14 (350mm) requires proper tools and equipment. Pipe having a wall thickness greater than

As compared to grooving or welding pipe , the pipe wall thickness must be thicker to accommodate the cut-in threads (ASME B1.20.1) for threaded pipe . NFPA 13 220.127.116.11 (2002-2016 Editions) addresses minimum pipe thicknesses for threaded pipe up to 300 psi, unless the pipe is separately listed for fire sprinkler use: PE FABRICATED FITTINGS FOR PRESSURE mechanical coupling , butt welding, or electrofusion jointing without sub-welded sections. The spigot ends, to be fusion welded, must be cut square and be of the same SDR as the mating pipe or fitting. Unmatched wall thickness will require machining or chamfering for SDR (fitting) to SDR (pipe ) jointing compatibility.
