发明名称 A CONNECTION ARRANGEMENT FOR A TWO-PIECE ANNULAR BODY
摘要 A drill pipe and casing protector comprises an annular body having two piece s (100) with identical edges. A first edge (110) includes at least two opposin g formations (115, 120) longitudinally formed thereon whereby when one piece i s 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 dril l pipe as well as around a bushing assembly.
