Shop Test

Filed under: Blog — Roman @ 7:27 pm

Today we were tested on the skills required to cut, bend and crimp copper tubing, flare and swage the ends, and silver-solder joints together. At the end, our pipe projects were submitted to 200psi of nitrogen and submersed in water to check for bubbles (leaks). Yours truly got a 100.

Here’s some pictures:

This is the complete assembly of three swage joints and a crimped end. At the short end of the L I had a flare nut which the nitrogen was attached to. We had to cut the flares off to return the nuts before the end of class.
