4. To find the corresponding point on the opposite side of the pipe (180° away), divide the measured pipe
circumference by 2 and measure this distance along the circumferential line from the zero point. Take the 180°
point measurement from both over the top of the pipe and under the bottom of the pipe (on a horizontal pipe) to
ensure accuracy of the installation. Mark a small scribe line at the 180
