Example aspects of a pipe clamp assembly can comprise a pipe clamp comprising a first clamp segment and a second clamp segment, the first clamp segment defining an inner surface, a first end, and a second end, the second clamp segment defining an inner surface, a first end, and a second end; a projection extending from the inner surface of the first clamp segment, the projection defining a linear top edge configured to engage a pipe, the linear top edge oriented distal to the inner surface of the first clamp segment; and a support flange coupled to the pipe clamp proximate to the first end of the first clamp segment and the first end of the second clamp segment, the support flange configured to support the pipe clamp assembly on a support surface.
