Thank you for showing me your incredible simple effective way to coil copper pipe.

The waterfilling is a good tip, thank you for that. I have a tip for you too. You should make the coil in such manner that it does not touch the stainless steel pipe (inner) wall to avoid contact corrosion. I suspect the coil leaks are caused by this. Copper in contact with stainless steel in a slightly acidic medium and slightly elevated temperatures will gradually dissolve. If technically possible isolate the copper coil from the ss pipe wall by means of an insulator of some sort and shape. this could be a thin wall plastic pipe with a tight fit into the ss pipe. A secondary corrosion protection could be to establish an earthing connection wire between the coil and the ss pipe. Best regards from Bert in Spain

"galvanic corrosion"
@hvacstudent9672 жыл бұрын
I have a stainless steel tank I'm turning into a rocket mass hot water heater, I have 1/2" copper I'm going to bend into a coil, was going to use copper connectors going through the wall of the tank. I see there is a problem long term with so called galvanic corrosion? If so you recommend several work arounds, because this will be in a wood heated / gaseous environment, the through fittings I mean, I don't think plastic pipe is a good option, can you explain earthing connection wire?

If you don't have the strength you can use a small pipe about 6" the inside diameter just a little larger than the tubing and slide it over the tubing it will give you leverage to coil the tubing as it feeds out the end of the pipe.

@janemorong49702 жыл бұрын
@@emmett117 Yep, sure did. Here's the basics.... take a metal trash can and drill four 2 inch holes. 2 of them a little above the bottom, 2 of them about midway up. Then take a coil of copper (3/8 or 1/2) and put it on top, then cover that with a lid, letting the copper lines stick out. Now get a cheap $20 pump off Dr. Evil's Lair (Amazon) and an old hot water heater, remove the drain valve and bottom element, and connect the lines to these ports - the pump should be pulling water from the drain valve and returning it to the bottom element port. Now start a fire in the trash can. The more turns of copper coil, you have on top of the fire, the more efficient it will be (up to a point of diminishing returns, obviously.)

But the main question is what diameter sizes and wall thickness can you bend when it comes to tubes and pipes of different materials ?????? I am looking at it only from local hardware stores or for home building/residential building which is small interms of the whole engineering buildings for commerical and industrial. I rather not just know for small scale home building but any engineering pipe size on earth a more general question.

You should fill it with boiling water make it boil before you pinch it off because boiling forces all the dissolved gases out of the water

Nice trick with the water filling to make no kinks when bending. You simply crimp the ends after filling with water then bend and then cut ends of to drain water. No major pipe bending tools required for this diameter pipes/tubes

Just a curiosity not a big deal as i probably wont get to touch or even need to touch any of this commerical/industrial building stuff. As i like off/on building house not sure i be up for the challenge of building big high rise buildings anyway. But is a curiosity about what is practical to bend with pipe bending tools/machines. And when it all needs to be more molded/casted into the shapes not bent.

I am skeptical about the value of filling with water. For the bend radius shown in the video, you may have achieved equally satisfactory results without any filling whatsoever. Water exerts equal pressure in all directions, so it would make it significantly more difficult to bend around the mandrel. Also, any small leak would make it completely ineffective. For small bend radii, I think that using sand or salt would be better.

Sir, Thanks for the comments. I made 3 inch radius in half inch copper tube. Water is better option for me, easy to remove ( fleshing and vacuum) . I used the coil for a Refrigeration purpose
