COMPOUND PIPE BENDS
In constructing a pipe line to conform to a certain contour, it is sometimes necessary to use both vertical and horizontal angles. The construction is greatly simplified if the pipe is bent to one angle which will accommodate both horizontal and vertical deflections.
The following formula will give the pipe angle which will occommodate two vertical angles and one horizontal angle:
The minus sign (–) is used when both vertical angles (A and B) are above the horizontal, and the plus sign (+) is used when one vertical angle is above the horizontal and the other vertical angle is below the horizontal.
Two examples will illustrate the use of the formula :
