How Professional Plumbers BRAZE COPPER LINES

[@RogerWakefield]

Do you think you're ready to braze copper now?

[@Cruiser052]

Hey Roger, I've been a plumber for about a decade. We typically don't do a lot of silver soldering on the plumbing side of the company I'm at. HVACR is constant. Every now and then we will do a 90 under slab if a print calls for a rigid copper main, we usually end up doing roll copper or a pvc main. I have ran across some soft copper silver soldered into a galv nipple on a service call. That was amusing. Got any tips on keeping roll copper round without fighting with it? I'm talking 2 to 4 inch here.

[@SuperDave-vj9en]

@Cruiser052 Use a swag for the right size copper tubing. Some are stepped for varying sizes, but round out the pipe for great soldering joints. Most plumbing supply houses carry them. 52 years in business this year!

[@Cruiser052]

@@SuperDave-vj9en lol. My locals don't carry 2-4 inch swage tools.

[@SuperDave-vj9en]

@Cruiser052 Order them! Time saved for trying to get large copper tubing round is well worth it. Better yet, have a machinist make you one for probably say a hundred bucks. You do know what kind of tool I’m talking about, right?

[@Cruiser052]

@@SuperDave-vj9en I do. I've swaged couplings into soft before but the only ones I was able to get were small sizes. I don't know why it never occurred to me to get big ones.

[@scottkanehl4524]

As a newly licensed residential plumber, I took a job with an independent engine testing facility as the plumbing department. This facility had never had a plumber, even through a lot of expansion, yet the plumbing demands have been pretty enormous. My first year I had to renovate a 250,000 square ft. facility to accommodate 10 engine test cells, as well as change multiple bathrooms, and kitchens. I've had to figure out, on my own, everything from brazing giant heat exchanger coils, to 3" high pressure gas lines, to industrial RO systems, to 12" underground cpvc drainage systems, to multi-million dollar home builds, to 1000' 8" insulated, chilled water lines, hung 25' above the floor. All of this almost totally by myself. I wish I had access to this channel 10 years ago. My stress level would have been much lower. I still learn something every time I watch.

[@BridgeWater94]

Your story kind of reminds me of what I’m going through right now. Except I’m a total noob/apprentice. A company hired me as a hvac tech fresh out of trade school. I’m the only tech there and have no one to teach me questions I have in the field. Just resorting to figuring everything out on my own. It can be daunting at times but I told them I’m very new to all this. Been working 4 months so far.

If this was for a refrigeration system of an air conditioning system, they would use a special flow regulator to have nitrogen flowing at about 3 cfm through the copper tubing to prevent flakes from building up on the inside due to the high temperature.

Nice video Roger, but I would like to go over some things not mentioned.#1 brazing is a technique acquired from practice and constant use ( brazing everyday). No offense Roger but it is hard going back and forth from soft solder ( the main bread-and-butter for plumbers) to brazing ( infrequently used by plumbers) and I could tell by your brazing technique this is something you probably rarely do anymore ( no offense, it just means you're out of practice). I can guarantee you, if you made this video after coming off a one month Med gas project, your technique, comfort level at brazing and the joints themselves would be night and day.#2 let's mention some things copper brazing is used for ( Med gas lines, gas lines=natural gas and propane, refrigerant lines , chemical lines & underground water lines) can anyone list some more? #3 this is the 21st century, we should be introducing nitrogen to these lines anytime cleanliness & inside corrosion may become an issue ( so let's say 90% of the time) . The introduction of nitrogen when brazing Med gas lines and refrigeration lines should be mandatory. I like to hear the thoughts of other plumbers and pipefitters out there on this subject.Roger keep the videos coming, you provide a great platform for conversation & education ( we can all learn from one another & Lord knows none of us are perfect).

Problem is the US is behind the times. Using a flange pipe tool and making thread connection is the only real way to prevent impurities from getting in the line.

[@SEaudiofan]

I silver brazed copper, brass and stainless steel for 30 years. The 1st job was radiation therapy equipment, the 2nd was for aircraft sunvisor mounts. I used a t-drill a lot in the 1st job. In both applications we used Harris, white paste flux and 45-55% silver rod, 1/32-1/16" diameter. I used a bit cooler flame, heating the socket primarily, in order that capillary action would fill the joint 1st. When I knew (by experience) the joint was full, I would stop and let it cool, quite a bit before moving it. We used jigs and fixtures whenever possible. If it was desired to have a nice fillet visible, I would clean the joint well then reflux and heat primarily the tube then let it flow around it. We dressed the joints down with files, sandpaper and polishing wheels til they looked really nice. Getting the t-drill lube cleaned thoroughly out of the socket was usually a bit of a challenge.

[@SEaudiofan]

Another thing I recall, a "cap" could hide a socket that wasn't filled, to the point of leaking under pressure. A small fillet, or none, would show a full circumference filled. Also, I believe I tended to avoid applying flame to the actual area where the rod would enter the joint, as it's possible to burn the flux, and then it will fail to flow the filler in that spot

[@Stuart68505]

If this was done on an air conditioning system or on refrigeration tubing it would require having a small flow of nitrogen in the line to keep from creating black flakes inside the tubing where the brazing is being done. Helpful concepts thank you. You could have specified what you trick is but it seemed to be creating a “cap” all around the tubing. I like the reamers that have a cone internally and an outward cone. In refrigeration it would be important not to leave the chips from reaming in the tubing as they could cause problems in the system & plug up filters at an expansion valve for example.

Everyone I’ve talked to says to use silver solder to do the repair since I’m dealing with brass. I have a Benzomatic propane torch. Am I on the right track here? Any tips?

[@shineperishingrepublic]

The technique in the middle of brazing the right side where you stuck the solder up and melted a new stick to it instead of just grabbing another stick..... amazing. To me that was where your experience and wisdom were doubly apparent. I love learning from this channel. Thank you Roger.

[@evanbowser6571]

Me personally, as an HVAC/R technician, I feel that is a lot of braze. Usually, when I braze, it's for refrigeration lines. So time on the pipe, amount of braze, and heat is critical. (Flowing nitrogen helps as well.) I typically don't "paint" the joint. I will have the heat pull it in at a 45 degree angle. Once it has filled my gap, pull the heat off as you round the fitting to make a crown. Still a great video! Even though I am a HVAC guy, I love your videos. Some of your pipe techniques have helped me make some radiant heat jobs look superb!

You should never wear latex or nitrile gloves when dealing with extreme heats or extreme colds.

Man did that in 14 minutes I’ve seen 30 min videos on this. TRUE PRO

[@jalenmcgee2901]

I’m actually a certified brazer in a manufacturer. I braze Hair Pens on Condenser coils for 25Ton commercial units. I use a Y tip and it’s the best this to use when brazing. Heats both sides of the pipe and can have beautiful professional looking brazes. I could braze what you did in the matter of 20 seconds. But very educational video

[@GD-qu9hr]

Ive been a plumber here in the uk for many years and i think that is the worst joint ive ever seen, wow

[@pingpong9656]

Do they have a Y tip for a acetylene air turbo torch?

[@justinparker3791]

As residential plumbing service technician what reasons would I ever have to braze instead just soldering

[@dougslawson4804]

Under ground copper service line to the house at 2:30 in the morning and no mechanical couplings? I'd hope you would have a torch.

[@prophetoftears]

I don't know about the solder, but I do know that rapidly cooling copper actually makes it softer and less brittle. Letting it cool slowly is how you harden copper. That's why it took so long between the Copper Age and the Iron age, even though iron is more abundant, working the two materials was basically the opposite. Learned that from black smithing.

[@hotbam37]

good to know, thanks

[@elainerussell924]

Wow this video showed me how not to braze thanks roger

[@alexjackson1270]

That's why people tend to stay away from shocking it right after u burn. But in some cases I will.

[@mikemorgan5015]

Not really. Copper won't harden when quenched or air cooled. Copper "work hardens", like by bending, hammering, drop forging, etc. Try it. Heat up some copper and quench some and air cool some. Both will be dead soft. Now bend it back and forth. The original bend area will harden and a new bend area will be created. The same area won't keep bending until it breaks like iron or mild steel. Now heat the hardened area and it's annealed dead soft again and ready to bend once more. You can heat, pound, heat, pound repeat over and over and make copper foil if you like. But if you pound too much without annealing again, it'll crack.

[@birdshitsmallchange9840]

These hands on videos are GOLD thank you

I have learned so much from your videos and I've been plumbing for almost 5 years. Just absolutely amazed by your skill and knowledge that's forsure. I'd love to chat with you and learn more off you because you are the man! Love your videos, you're truly my inspiration Roger!!!

Thank you so much. Greatly appreciated!!!

@RogerWakefield I actually started my own KZbin account because of you. You're such an inspiration and have been do detrimental to me career it's unbelievable! Thank you so much for everything you do and if you were need a video to feature, I got a few gross ones lol.

[@Restrictted]

Can you do a video on whole home water cooling for my PC? I want a long loop of cold water to circulate around my house so my PC always has cold water available and the hot water will travel around the loop turning into cold water again.

[@DGTelevsionNetwork]

Why can't you just use regular water cooler? Running that kind of system in city water would drive your water bill through the roof I would assume

[@Ddabig40mac]

@@DGTelevsionNetwork , I think he is talking about a closed loop water cooling system, just one that relies on tubing length to replace both reservoir and heat exchange manifold.

[@nickgalaini4152]

Honestly, I think ear protection is pretty important. I install HVAC systems and don’t recommend gloves that could melt onto your skin(I don’t wear gloves when brazing). I also thought this took quite a bit longer than needed. I’d have had the pipes cooled and ready to pop the schrader valves back in.

[@a.howardsmith3243]

Give him a break. Training videos always make you squirm.

[@Chilldil86]

[@RSole9999]

As someone else mentioned, quenching hot copper with water makes it soft, nice if you need a slight bend in hard pipe. But as Roger said, quenching a joint may cause a crack in the joint.

[@mattlent1741]

Cool vid Roger, always been wondering about silv soldering, haven’t got that far in my career yet to learn and do it but a few years and I will be going for my med gas ticket here in Canada, good job this far on the channel to brother let the haters hate at the end of the day there just jealous you can do what they can’t!!

What type of cloth is that green one you used second? What is the name of that silver solder used. Good i instruction.

Can you clean the soldering rods with the abrasive pad if it is oxidized, or should you scrap the rod with out trying to clean it?

[@RogerWakefield]

You can brush off the oxidation if its not too bad, I have done it before. If the rod is really oxidized however, I would recommend just replacing it...

Hi I’m a third generation in plumbing. I’m 25 years of age my father and grandfather were master plumbers. I grew up calling this sweating. “Go sweat that coupling in”

15 minute video & you spent about 11 minutes reaming 🤣 (there's no pleasing some people)!

[@DoesTheNetWork]

Im learning from my brother who is a Plumber in NYC and needs a specific Med-Gas certification and from what he has told me is that the cleaning before you braze shouldnt go to far passed the end of the pipe because there is a protective coating on the outside of the pipe that helps prevent oxidation. In that case cleaning the coupling (on the outside) after would also remove that oxidation prevention layer.

[@JurassicJolts]

That stick combining tip is so awesome

[@wargamingsupernoob]

Same thing works if you are oxyfuel welding. heat both tips up and they fuse together. Overlapping is the best so you don't burn through one rod and have to push them together and get a big glob where they joined.
