New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

What are the difference in lengths, offset, and travel for a 45-degree equal spread offset with a run of 32 inches and a spread distance of 8 inches?

1. 3-5/16, 45-1/4

2. 4-1/4, 50-1/4

3. 3, 40

4. 3-1/2, 44-1/4

The correct answer is: 3-5/16, 45-1/4

To determine the dimensions for a 45-degree equal spread offset, it's essential to apply the appropriate formulas for calculating the lengths involved. In a 45-degree offset scenario, there is a relationship between the run, the offset, and the travel. The run refers to the horizontal distance between the two points where the offset will occur, the spread is the vertical distance between these two points, and the travel is the total distance of the pipe. For this specific offset, a run of 32 inches means that the horizontal distance across is 32 inches. Given a spread of 8 inches, we need to find both the actual lengths of the offset sections and the total travel distance. Using standard formulas for a 45-degree offset: 1. Length of each offset leg can be calculated using the Pythagorean theorem since the offset creates a right-angled triangle: - Length = √(Run² + Spread²) - With a run of 32 inches and a spread of 8 inches: - Length = √(32² + 8²) = √(1024 + 64) = √1088 ≈ 32.98 inches. 2. The travel in this case would involve the horizontal run
