That cant be done because as long as there is water in them the temperature of the pipe wont go up enough to allow the solder to flow. you have to remove the water.
It is called Brazing rods or lead free solder
No, it will not affect them
Sandcloth the end being soldered. Squish the end with pliers so it is tight. Put flux on the end and solder. Easier to buy a copper cap and solder that on!
To effectively solder copper pipes, follow these steps: Clean the pipes and fittings thoroughly with emery cloth or a wire brush. Apply flux to the cleaned surfaces to help the solder adhere. Heat the joint evenly with a propane torch until it is hot enough to melt the solder. Apply the solder to the joint, allowing it to flow into the connection. Let the joint cool and wipe away any excess solder.
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes
It melts solder. Solder was originally a mix of lead and tin that was used to join copper to copper (pipes and wiring) It is in the shape of a pistol, but does not shoot anything.
Lead free solder for potable water pipes
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes
I can't think you are talking drinking water pipes because anitfreeze is poisonous. Nor should you have lead pipes or lead solder in drinking water pipes. So either sleeve pipes or heating pipes then. Antifreeze has inhibitors designed to prevent corrosion.
Yes, natural gas can corrode solder on copper pipes over time. This is due to the sulfur compounds present in natural gas that can react with the copper and cause deterioration of the solder joint. It is essential to use approved materials and proper installation techniques when working with natural gas lines to prevent corrosion issues.
First off, you should shut off the water source. Then you must drain the pipe. After that you can clean up the area to be soldered, apply some flux. Now you are ready to solder. The pipe doesn't need to be bone dry, since it will dry as you solder from the heat.
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
