Q&A for How to Bend Pipe

The pipe will not grow in length if you bend it properly so that it does not collapse across its diameter.

If you have 1/4-inch copper tubing you can bend it with your finger in seconds. If you have a thicker tube and the correct bending tools, seconds or minutes. It depends on the tubing, the materials you have, and the number of bends you wish to make.

Cut the pipe into tiny pieces, like bracelets, then when done cleaning the separate pieces, glue and tape back together.

The length is 50cm. If you have a 50cm pipe, and you bend it, the length of the pipe will still be 50cm.
