Disclosed is a device for centralizing an elongated body, such as a pipe, in the opening of a mousehole machine along the machine's center axis. The device includes two centralizing bows supported within the opening and adapted for rotation about a common, mainly horizontal axis of rotation that extends across the opening of the mousehole machine, the bows being located on radially-opposite sides of the axis of rotation. Upon rotation of the bows, the pipe is moved by contact with a first of the bows toward the center axis until the second of the bows contacts the pipe. |
