Title: Assignment: Tubing and Brazing
Course: Canvas Practice Course

The student shall construct a rectangular loop using 4 equal lengths of 3/8" copper ACR tubing, each approximately 10 - 12" long.   Each length of tubing shall be bent 90 degrees at the midpoint of each length.   The tubing shall then be swaged so that the 4 pieces can be formed into a rectangle and brazed together.   The student will then burn a small hole into the tubing so that an access port can be brazed into the loop.

The finished loop will then be pressurized with nitrogen to 100 psig in order to verify that all connections are free of leaks.
