Abstract:
A clevis pipe hanger having upper and lower yokes and a clevis bolt or stud defines a pipe support aperture with an inner diameter of predetermined range, measured along a horizontal plane through the center axis of the pipe and parallel to the axis of the clevis bolt, that is greater than the predetermined distance between opposed, inner surfaces of the ends of the upstanding arms of the lower yoke, whereby, in the regions near and below the horizontal plane, the inner surface of the lower yoke engages the outer surface of the pipe. In the regions above the horizontal plane, segments of the inner surfaces of the upstanding arms lie generally tangent to the outer surface of the pipe and extend generally toward each other. In the region of the arms lie approximately parallel to each other.
