2-inch Pipeline deflection
2-inch Pipeline deflection
(OP)
Can someone please help me with this question? I have been trying to solve it but I have not been succesful. 
What is the maximum deflection of 2-inch pipe in number of degrees (maximum deflection in number of degrees that the longitudinal axis of the pipe may be permanently deflected in any length along the pipe axis equal to the diameter of the pipe)?
Pipe description:
Carbon Steel, Schedule 80, wall thickness 0.218”, MAOP 2500 psig.
Thank you in advance!

RE: 2-inch Pipeline deflection
Deflection as I know is a dimension, not angle, you can calculate the deflection angle when you know deflection and the span of pipe. Now, the angle = arctan (deflection)/(span/2). For max defelction you have some criterias, for power piping B31.1 0.1 inches & for process piping as Kellog 0.5 in to 1.0 inches.

This question came about a project where 40' lengths of pipe is being welded together, and now that the contractor is getting ready to lay it at the bottom of the ditch. 2" welded pipe is flexible however it will have stress areas because they did not manually bend the pipe.
So I now need to figure out how many degrees can the pipe flex (self bend) before is requires mechanical bending?
