ive groved 5 and 6" in place. Works good but you need the space to spin the roll grover. It takes longer and does require proper adjustments. 1 advantage is the pipe and fittings can be disassembled like no hub.
~~What a luck! Talking about future repairs and I found a small drip on a 4” copper pipe leaking at the elbow. It is very complicated because it involves a lot of work because the system has not isolation valves, so can I use something called Roll Grove in this joint –pipe to elbow? Or is there another alternative besides that? If this joint need to be taking apart to solder, can I go soldering using Mapp or Brazing. Being new in this commercial thing I need help and thanks for everyone
i doubt you will unsolder a 4'' elbow without actually cutting it in 1/2 and then trying to unsolder it. there should be trapped water and there's probably no play in the line to spread it. plus mapp gas is not going to cut it unless you have a hell of a torch tip.
roll grooving will work if there is enough clearance around the line to spin the tool, but you will still need to cut back the copper and or un-sweet the fitting.
Well, they don't want to spend money and I have to repair it with things I have. I will cut the the pipe on two sides and install new 90, coupling and 2 pieces of pipe (L) I only have Mapp, flux and the solder. Can I do this job with those or I will need brazing and the equipment for. Any help is appreciated
all gases get hot enough to melt solder. the issue is the size of your torch tip and i doubt a 16oz. bottle of mapp gas will have a large enough tip to properly solder 4'' copper. i've done 2'' plenty of times with a mapp turbo torch, but 4'' is 4x the mass of 2''.
