  • Ridgid 300 machine

    I am having problems threading schedule 80 seamless pipe.
    The maching slips and cannot hold the pipe while threading, usually the 3/4 and one inch pipe. I also am having trouble with the threads. One would be perfect (2.5 turns by hand) then the next will only turn once. I tightened the handle so the die didnt slip, but the treads were still different.
    So my question is when threading schedule 80 do you need different dies than regular schedule 40 dies?
    Do you think the pipe is slipping because of the paint used on the schedule 80?
    Thanks for your advice.

    sounds like equipment needs a tune up or be replaced

      Either clean or replace the vice pads (they pop right out) and make sure the die set is new and installed properly. The 300 uses the same dies for sch 40 & 80

        Thanks for the reply. I think it needs a tune up, and I didn't know that the dies are the same. thanks again

          when i thread gal pipe, there is a tendency to slip if not tightend all the way down. the gal acts like a lube.

          either clean the paint or replace the jaws.

          the machine doesn't know the difference between sch. 40 or sch. 80. the cutting wheel and the reamer will notice. the dies thread to the same depth for both 40 and 80.

          clean your jaws, and change the old oil. adjust your dies on a factory nipple and try again.

            i suggest you replace the chuck jaw set. and try using universal high-speed dies 1/2 - 3/4" and 1 - 2"

              Thanks for the advice. I really am amazed on the responses i got.
              Does anyone think it might just be a bad run of pipe? Is that even possible?
              Because we would get a perfect thread then the very next one be wrong. It can be very frustrating.

                How can I tell if I am using high speed universal dies? Does it have any letters on them?

                    If you're talkin about the pic on the left of a persons response, you go to user cp at the top left of the page and then to edit avatar. Either upload a resized pic from your computer or load one from an online source.

                    As for the original post, sounds like your rig needs a tune up. Should'nt slip like that if the machine is in proper working order. I would also check my dies and look at the threads they are cutting on sched 40. If your starting threads are choppy or chunking out, its time to replace the dies.

                      had that problem with crappy and threads going from good to bad. I found the prob was when you close the die head handle down(threading position) not all of the chases would engauge to the "threading position" make sure your chases are in thrie corrisponding # slots and that the allen key screws that hold the 2 halves of the die head together are tight. Maybe take the allen key screws out and make sure the chases arent getting gummed up on the inside of the die head. good luck
