- Diameter: Solder is out there in varied diameters to go well with totally different pipe sizes. Smaller diameter solder (e.g., 1/16″) is used for small pipes, whereas bigger diameter solder (e.g., 1/4″) is used for bigger pipes.
Flux: An Important Support
Flux is one other essential materials utilized in soldering copper pipes. Flux acts as a cleansing agent, eradicating oxides and impurities from the steel surfaces, permitting the solder to stream extra simply and create a powerful bond. It additionally helps to stop oxidation throughout the soldering course of.
There are two primary sorts of flux utilized in copper plumbing:
| Sort | Description |
|---|---|
| Acid-based flux | Acid-based flux is the most typical sort utilized in plumbing. It’s extremely efficient however may be corrosive if not correctly cleaned after soldering. |
| No-clean flux | No-clean flux incorporates delicate acids and leaves little to no residue after soldering. It’s dearer than acid-based flux however eliminates the necessity for post-cleaning. |
You will need to choose the suitable sort of flux for the particular soldering utility. Acid-based flux is usually greatest fitted to heavy-duty plumbing tasks, whereas no-clean flux is good for smaller, delicate work or the place post-cleaning is tough.
Getting ready the Pipe and Fittings
Earlier than becoming a member of copper pipes and fittings, it’s essential to make sure they’re clear, correctly lower, and deburred. Here is an in depth information on how one can put together the pipe and fittings for profitable copper pipe connections:
Cleansing the Pipe and Fittings
Take away any dust, oil, or particles from the pipe and fittings utilizing a clear fabric and isopropyl alcohol. You can even use a flux brush to softly scrub away any cussed residue.
Chopping the Pipe
Use a tubing cutter or hacksaw to chop the copper pipe squarely. Make sure the lower is clear and freed from burrs. For skinny-walled pipes, you need to use a utility knife.
Deburring the Pipe
Use a deburring instrument or a pointy knife to take away any burrs or sharp edges from the within and out of doors of the pipe’s lower finish. This may stop injury to the O-rings or seals throughout meeting.
For extra detailed directions on making ready the pipe and fittings, confer with the desk beneath:
