Using a copper pipe expander, or swaging tool, is a straightforward process that allows you to enlarge the end of a copper pipe so it can accept another pipe of the same size, creating a solder joint. Here's how:
Steps for Using a Copper Pipe Expander
-
Prepare the Pipe: Ensure the end of the copper pipe you intend to expand is clean and free from burrs or dents.
-
Select the Correct Head: Choose the appropriate sized expansion head for the pipe you're working with. Copper pipe expanders usually come with multiple heads for various pipe sizes.
-
Insert the Head: Insert the chosen expansion head into the end of the copper pipe you want to expand.
-
Begin Expanding: Start squeezing the handles of the expander tool gradually.
-
Continue Squeezing: Continue squeezing the handles firmly until the end of the pipe is fully expanded.
-
Release the Tool: Once the pipe end has been sufficiently expanded (swaged), release the handles of the expander tool.
-
Remove the Expander: Carefully remove the expander from the swaged pipe end.
Key Points to Remember
- Gradual Expansion: Expand the pipe gradually to avoid damaging or splitting it.
- Consistent Squeezing: Apply even pressure when squeezing the handles for uniform expansion.
- Proper Sizing: Always use the correct sized head for the pipe you are working with.
- Cleanliness: Make sure the end of the pipe is free of debris.
Summary of the Process According to Reference
As stated in the reference "Swaging with a Tube Expander", the process involves fitting the head into the end of the tube and gradually squeeze the handles. You should then release when the end of the tube is fully swaged.
In essence, it's a mechanical process involving the insertion of a tool and gradual pressure to manipulate the end of the copper pipe.
