We have an engineer who wants to require bead removal from the inside of pipes ranging from 8 inch through 44 inch.
I can find machines for this, but really don't think that it is easy. It seems to me you have to stop everything in your welding operation while you remove a bead, before you can go on to the next one.
How much production time is lost doing this?
Who out there has done this, and what are the headaches?

The downtime you have is very minimal. If you are fusing a 40' length of pipe, you would install the bead removal tool as soon as you bring the pipe ends together in the fusion process. Then you would wait until the cool time is completed, push the tool over the bead and rotate the handle 360 degrees to remove the bead. Then pull the bead tool mechanism from the pipe and would lose no more than 5 minutes per joint.

Hope this helps. We don't make tools as large as you are discussing yet but we have made tools up to 18".

How does bead removal affect the joint?

The removal of the bead does not affect the joint strength. Many companies in the UK remove each bead to determine if they have a good joint by looking for voids in the bead.
