In response to all, I appreciate all the input. To further clarify what i am dealing with, the line is 6" schedule 40 pipe, it is located between the compressor and 3 wells that tie into it, the leak is right about half way between the compressor and the first well tie in, which is approximately 1/4 of a mile either way, the only valves they have for blow down purposes and isolation, is at the compressor and the wells. The company man indicated to us that there was usually about 30lbs of pressure on the line under normal conditions, at times as much as 150lbs. we do have all the monitoring devices required, the last repair i made on the line we had approx. 2 to 5 lbs. flowing through the line throughout the repair with a man for fire watch, and one with a weed burner to make sure that the fire did not go out. the cutting and prepping was done with a torch beveler, and 4 1/2" grinder, i did use 5p and did leave the top open until i got the root and hot pass in then sealed off the top, however the reason i asked about the rod in my original question is because, the closer to the bottom of the pipe i got the harder it was to keep the arc going, the flame was burning the flux off faster than i could move, so when i got to that point i switched to 3/32 7018 and went from the bottom up and tied into where i left off with the 5p, i don't know what an inspector might think of that, but it worked well,experience has taught me that there are times and applications where bending the rules on welding procedures, is almost a necessity, thats where common sense and experience pay off, you can't teach that in a classroom, unfortunately, anyway there's the long and short of it. Thanks Steve.
Steve,
"i don't know what an inspector might think of that, but it worked well,experience has taught me that there are times and applications where bending the rules on welding procedures, is almost a necessity, thats where common sense and experience pay off, you can't teach that in a classroom"
No matter what you may think bending the rules on welding procedures is not common sense - most jobs I work on it would have you run off the site quick smart.
Why even bother having welding procedures if every welder who thought he knew better just decided to do their own thing ???

C'mon now Shane, that advise in in clear violation of the Farm Code (FC-2002) which clearly states when in doubt to ask the welder. Get with the program!
Yeah, isn't the latest Edition/Addenda due on that document.
Where does the committee meet for this?
I'm hoping Hawaii or Vegas.
I had sent in a request to be appointed to the bamboo scaffolding and umbrella strut filler metals sub-committees but as yet have not had a response.
To you guys that do this type of work- solid brass ones
