cutting a clamped pipe off of it's threaded pin

admin

One of the operators handed me another one of his roll-on pins for me to cut out. It's a threaded attachment used to attach certain tools to their coiled tubing going down hole to drill, clean and whatever else they do.. Before they attach the tool, they clamp the pipe onto the pin the same way you clamp a fitting onto a high pressure hose. Every so often they're forced to cut part of their coiled tubing and start a new lead, so they come to me to rescue the attachment for continued use. Here is the before and after pics of one I did on friday. Each of those grooves sits an o-ring which needs to seal high pressure nitrogen they use through the coiled tubing, so any nick in those shoulders and the attachment is junk.I used oxy/acyt to cut the tubing from the attachment.

Reply:No welding involved here. Just torch work. Since the steel is clamped on with a press, there's little to no clearance from the shell to the pin, which makes cutting it off a bit tricky.
Reply:yea i guess it would be a bit tricky, but that why they got you to do it insted of just some fool with a hammer. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.
Reply:Alberta Fabricator, that takes a very steady hand. I have split things like that in the past and it is far different than your run of the mill torch cuts. Very nice work on a tricky job!
