Abstract: A method of making a bi-metal pipe section, and especially reclaiming a used or damaged pipe section by making it into a bi-metal pipe section which resists corrosion. The bi-metal pipe section is used in constructing a pipe line or production tubing that resists corrosion at the pipe coupling where corrosion is especially prevalent in fluid conduits. The bi-metal pipe section is fabricated by first removing an annular marginal end of a length of the pipe section of the prior art, to provide a long length of pipe having a partially threaded cut end opposed to an opposite end. Next, an annular short length of pipe is axially aligned and butt welded to the cut, end of the long length of pipe. The short length of pipe preferably is an annular metallic alloy having greater resistance to corrosion respective to the long length of pipe.

Abstract: A guide means is removably affixed to the derrick of a workover rig or the like for capturing and stabilizing a medial part of a pipe section as a pipe string is being made up and run into a wellbore. The guide apparatus is pivotally mounted to the derrick so that it can be extended into operative relationship respective to the pipe section, and is retracted clear of the string by remote control. The apparatus includes a yoke which is pivoted from a substantially vertical into a substantially horizontal position. The yoke is adjusted so that the apex thereof coincides with the central axis of the pipe, and as the yoke is moved from the retracted to the operation position, the pipe section is forced to move into the yoke apex, thereby properly aligning the pipe section with the pipe string and with the borehole. Adjustment means enables precise orientation of the yoke respective to the axial centerline of the pipe string.
