Minimum Hydrotest Bend Radius Analysis

During a hydrostatic test the line is pressurized well above its operating pressure, and any bend in the pipe adds longitudinal stress on top of the elevated hoop stress. This analysis returns the minimum bend radius the pipe can hold at test pressure before the combined stress reaches the code-permitted percentage of SMYS.

It keeps a field bend or an HDD sag bend from being overstressed by the test itself.
