Abstract
The support assembly is constructed so that an aboveground pipeline resting thereon can move longitudinally and laterally relative to the path of the pipeline to allow for normal thermal contraction and expansion in the pipeline. The support assembly is also designed for earthquake contingencies to prevent damage to the pipeline and to the support assembly upon occurrence of relative movement between the pipeline and the support assembly that is greater than that encountered with normal thermally motivated movement. The support assembly includes a pair of vertical support members spaced transversely at a given location along the path of the pipeline, which vertical support members are interconnected by a transversely oriented cross member. The cross member is adjustable relative to the vertical support members to orient it horizontally and is further adjustable to accommodate tolerance variations that occur during the fabrication and construction of the components of the assembly. A sliding shoe rides on the horizontal upper surface of the cross beam. The shoe has two pairs of stanchions pivotally connected respectively to two clamps that wrap about the pipeline. The stanchions hav…
