Syphon elbows
The conventional 60° elbow has a large bearing area for the hinge pin and the material greatly increases yield and tensile strengths.
Determining Length of Syphon Pipe Used With 60° Elbow
1. Calculate dimension "A" by dividing the internal roll diameter by 2.
2. Subtract the desired syphon clearance (dimension “B”) from "A" and multiply this result by 1.155 to find dimension "C".
3. Find "D" in the chart and subtract “D” from "C" to find the length of the angle pipe over the thread.
