This was never meant to be an instructional video. It was a local 38 plumber doing 1 joint with an owner's rep for kicks and giggles (comradery). But for what it's worth, this is an 8" domestic water line in an underground garage, brazed with nitrogen purge. If I remember correctly the newer code year permitted flanged ductile iron but we were between code years and had to stick w/ copper vs. ductile iron.
I have a few questions. But first, dope video. Not alot of videos online on what we do in the field. Is that a MT-610 torch tip? I can’t imagine it NOT being and if it is…did you have to twin (2) acetylene tanks together ??
I could tell by the size of that flame they only got at most 50 percent penetration. YOU ARE supposed to get a hundred percent penetration ! For 8 inch you use a combination of 2 rose bud torches or a 32 size tip turbo torch with a rose bud combination and work it in the first time because trying a second time is going to be tough. I'm just saying.....
@@1989Chrisc If you do not purge nitrogen while brazing you will get oxidation,looks like black soot that will plug your metering devices and filter drier. Just cut open a piece of pipe without using nitrogen and one where you used nitrogen the one with nitrogen will be nice and clean
@@billyflanagan3329 I will bet $1000 fake dollars that this is NOT ABOLUTELY NOT a refrigeration pipe. It is most likely med gas (oxygen) or a vacuum line of some sorts. Could be a chiller relief vent. Nitro purge doesnt change outer oxidization.
@@billyflanagan3329 Yeah, med gas requires a nitrogen purge, but this is probably a domestic water line. It was likely brazed rather than sweated due to it's size. The following chlorination will take care of any contaminant concerns for domestic water. Are you open shop?

She gonna bring that attitude home because she treated right in person and outside of weird gimmicks.
Ua all the way

I been brazing 21/8 pipe and man it sucks can’t imagine 8”
Looks like 6 inch pipe

By the way my name is Oz, and I learned this while I worked for RK mechanical out in Colorado.
Not true. A joint that has 2/3 braze penetration is just as strong as a braze joint that has 100 % penetration
I agree doing a lot of 6 inch type L lately.
@@ozcard2778 RK!? Worked for them many times in the past and always quit because of their ridiculous ideas. No you do not need 100% penetration.
A size 32 wouldn't come even close to being enough.
What a mess no nitrogen purge look at all the oxidation 😳
Do you have x-ray vision? How can you possibly know if there is oxidation on the inside of the pipe?
