  • Grooving 4 inch 316L Stainless Schd 10 pipes

    WE have a project coming up that will require us to Groove approx 73 Kilometers of 4 inch 316 SS shcd 10 pipes . What would be the best machine and are there any know issues with Grooving these types of pipes. We think with the Higher Nickel content of the pipes that there may be issues with roundness and surface cracking can you assist please

    All current RIDGID groovers can groove 4" sch 10 stainless. In our testing, the machines are capable of grooving stainless without any issues. Do keep in mind that if you are going back and forth between stainless and regular steel, you should maintain separate grooving rolls or thoroughly clean the rolls when switching materials.

    For the high volume and thin wall of the pipe, a model 916 seems like a logical choice. Models are available for use with many of our threading machines. The groove is driven into the pipe with a long lever that is manually operated. It is very quick and repeatable.
    A 918 groover would be another good choice. It is a much more substantial machine with a hydraulic pump and is well suited for a production environment.

        We used a Victaulic head on a Ridgid 300 for miles of the stuff, never a problem.

          just for clarification. the term grooving use to mean cutting a grove into the wall thickness.

          now we can no longer cut a grove. but we have to roll a grove. meaning force the pipe wall into itself and displace the wall without actually cutting a grove into the wall thickness.

          hopefully that's what it's like in your country too.

            We can cut a groove into sch. 40 or better piping and roll groove in piping that is less than sch. 40. Cut grooving provides a smooth ID with out the "bump" of the roll groove. Cut grooving is just about a thing of the past though, not many people have cut groovers or know how to use them, plus the oil mess you have to contend with.

            A 300 machine with a hydraulic groover would be the way to go, two guys can really make a dent in a pile of plain end pipe by the end of the day.

              Are you hiring? I'll bring my 300 and roll groover!!!

              That's 45.360097 miles of pipe.

                  one more question if we use ERW Welded pipe instead of seamless is there any issue with Roll Grooving on 4 inch Schdule 10 316L Stainless Pipes? Have heard from our opperations manager that the roll grooving causes problems at the weld joint in the pipe and causes leakes. Anyone know of this issue???

                    anyone know if there is an issue with ERW Welded pipe schdule 10 316L or 304 ERW 4 inch???? Have heard that the weld cracks and causes leaks. Do Rigid have any test data at all on 316L ERW Sch 10 Roll Grooving that they could share with us here in Singapore

                      Cut grooves are still used on large bore pipe, unless they've done away with it in the past 10 years.
                      Did some 18 and 24" Std wall chilled water and heating water lines with cut grooves.
                      From 8" down we rolled the grooves. 2" and under was all screwed.

                        You would be better off asking this question of Victaulic or Gruvlok.

                          Thank you for the Reply Bob D we are proposing to use Roll Groove not cut groove but our concern is the welded joint in the Seamed pipe, so does anyone know if there is an issue with ERW Welded pipe schdule 10 316L or 304 ERW 4 inch???? Have heard that the weld cracks and causes leaks. Do Rigid have any test data at all on 316L ERW Sch 10 Roll Grooving that they could share with us here in Singapore

                            As I work for Tyco Fire Contracting we also have grooved couplings (Grinnell) but the issue is the pressure from the Grooving process which one of our team has had some experience causes cracks in the pipe so we are concerned. Was looking for any test data that Rigid might have or others.

                              The country of origin on the pipe may have something to do with that, I have gotten cheapo 316SS fittings that were magnetic. We use all USA made pipe and never have a problem.
