A pipe support has an outer tubular support wall, an inner tubular support wall, spaced inwardly from the outer tubular support wall, and a connecting portion for maintaining the outer tubular support wall and the inner tubular support wall in a fixed, spaced apart relationship. The pipe support is intended for use in-trench and out-of-trench for supporting a pipeline during assembly, installation, testing and operation.

The pipe support of claim 1, wherein the inner support wall has a generally downwardly tapered frustoconical shape and the outer support wall has a generally upwardly tapered frustoconical shape. 4. The pipe support of claim 1, wherein the connecting portion extends between the first and second top ends, the first and second top ends and the connecting portion together forming the pipe saddle. 5. The pipe support of claim 1, wherein at least one of the inner support wall and the outer support wall comprises a support flange at the bottom end for engagement with the ground. 6. The pipe support of claim 1, the lower portion of the inner support wall having an inner support flange extending radially inward and the lower portion of the outer support wall having an outer support flange extending radially outward. 7. The pipe support of claim 1, wherein the lower portion of the inner support wall has an inner support flange extending radially inward and defining a non-circular installation opening. 8. The pipe support of claim 1, at least one of the inner support wall and the outer support wall further comprising stacking shoulders for elevated stacking of the pipe support and the like pipe support, when stacked in a non-aligned orientation. 9. The pipe support of claim 8, wherein the stacking shoulders are spaced at a distance from the first or second bottom end for elevated stacking of the pipe support and the like pipe support at a spacing between the first bottom ends of the pipe support and the like pipe support equal to the distance. 10. The pipe support of claim 8, wherein at least 3 circumferentially equally spaced stacking shoulders are provided on the inner support wall or the outer support wall. 11. The pipe support of claim 10, wherein the inner support wall and the outer support wall both include the stacking shoulders. 12. A pipe support for supporting a pipe section off a generally flat ground surface, the pipe support comprising: an outer support wall having a ground engaging first bottom end for engaging the ground surface and a first pipe supporting top end for supporting the pipe section;an inner support wall spaced inwardly from the outer support wall, the inner support wall having a ground engaging second bottom end for engaging the ground surface, and a pipe supporting second top end for supporting the pipe section, the second bottom end being spaced apart from the first bottom end; anda connecting portion for maintaining the outer support wall and the inner support wall in a fixed, spaced apart relationship;at least the first top end forming a pipe saddle for supporting the pipe section above the ground surface when the first and second bottom ends engage the ground surface;wherein the pipe support is shaped to be nestable with another like pipe support;wherein both the inner support wall and the outer support wall each have a generally frustroconical shape, whereby a taper of the inner support wall decreases in a direction opposite to a taper of the outer support wall; andwherein the pipe saddle is interrupted by at least a pair of radially extending and mutually intersecting grooves for stacking of three or more like pipe supports in an interlocking, non-nesting and stacked relationship. 13.
