ABSTRACT:
Device for facilitating the assembly of lengths of jacketed pipe base well screens in wells, wherein assembly is to be with manual or power tongs which have a greater vertical height than the blank pipe base end sections of the screens. The device includes a pair of pivoted semicylindrical portions which have compressible rubber liners at their ends which overlie the screen jacket and jaws at their ends which overlie the blank pipe. A removable pin locks the screen jacket end of the device at a fixed O.D. while the jaw end has a gap between the nonpivoted edges of the pivoted portions which permits a reduction in diameter as force from a set of tongs compresses the device and the jaws therein against a blank section of pipe.
