Cool. Yeah man, lots of work!! But worth it i think. For the tempering issue consider that the pipes will be under downward pressure and spinning. This will not be a smooth pressure and spin due to the bit chewing rock. Also when you get to the point of long depth/long pipe the piping is more vulnerable. A broken pipe 300-400 feet down is not fun. Have you guys opted for a new well as oppsed to going deeper with the existing well?
+JR MTG after talking to a few well drillers and doing some research we r going to dig a new well :) I don’t want to over harden the couplings and after talking to Steve I think we should be ok :)
You can check the welds around your pipes before you send them down the hole. ruclips.net/video/xEK-c1pkTUI/видео.html This video does a good job explaining. Amazon sells CRC WELD PENETRANT . Small cracks under stress and strain can grow into large cracks that fail. There are so many things that could of caused the cracks in the pipe. For example you started out welding the pipe with a MIG welder which can have inferior penetration. Was the original weld MIG welding that had poor weld penetration? But then you switched over Stick which has better weld penetration. But even with stick welding you have to be careful in which rod you use. Some rods are designed to give heavy penetration, while other rods are designed to fill in gaps between metal. The gap filling rods give less penetration so they don't melt away the edges of the metal of the gap you are trying to fill. Also I can see why multi million dollar rigs have heat treated pipes, the rig you have seems more on the simple side. Check the original welds with a file, if the file cuts into the weld easily they are not heat treated. If the file does not cut into them they are heat treated or possibly work hardened.
The pipes I welded like that have never disappointed me
Really interesting, thanks for taking the time to video it - Great Work!
What about taking and heating them back up to temp in the forge and rehardening the ends
+Nathan Tanner That’s plan B :) but thx for ideas:D
Had the same problem. I drilled four 7/16 holes in side of coupler then plug welded the holes. What thread diameter and pitch? I want to make new rod.

Were do you find those threads to weld on to regular black pipe?
How do you pick up work like this I been trying to get work on welding on rigs
Where can I get a water well drill
