A CONNECTION ARRANGEMENT FOR A TWO-PIECE ANNULAR BODY

摘要

A drill pipe and casing protector comprises an annular body having two pieces (100) with identical edges. A first edge (110) includes at least two opposing formations (115, 120) longitudinally formed thereon whereby when one piece is inverted with respect to the either piece, the first edges mate to form a pivotable connection allowing the body to be opened and closed about a pipe. The second edges (150) of each piece include opposing interlocks (135) which form an aperture along the second edge when the body is closed. The aperture receives a locking pin to retain the body in a closed position around a drill pipe as well as around a bushing assembly.
