ABSTRACT:
An apparatus for vertically supporting an internal conduit subject to temperature fluctuations comprising a conduit with shear lugs secured around its perimeter. These shear lugs rest upon a spool member surrounding the conduit that is configured to permit the thermal expansion/contraction of the supported conduit as needed. This spool member is, in turn, supported by an outer casing in a manner permitting the spool member to move or rotate independent of the casing. In this fashion, no rigid connector couples the internal conduit to the outer casing, instead a spool member provides the necessary support while being fully movable with respect to both the internal conduit and the outer casing.
