Apparatus for centralizing horizontally-moving pipe sections
Patent
·
OSTI ID:6602743
An apparatus which centralizes elongated members, such as joints of oilfield tubing or pipe and the like, is transported by a conveyor along a selected horizontal axis. An opposed pair of intercoupled centralizing rollers is spaced on opposite sides of the axis and cooperatively arranged to normally remain immediately adjacent to the surfaces of a pipe joint being transported by the conveyor. Upon passage of an enlarged portion or bent section of the pipe between the 2 rollers, control means are provided for selectively separating the rollers in unison, as well as imposing selectively increased opposing forces on the rollers as necessary for retaining the pipe in alignment with the axis.
