Claim:
A pipe disconnection system for disconnecting adjoining pipes, the system comprising: a male end of a male pipe having a longitudinal axis; a female end of a female pipe, wherein said male end is inserted within said female end with a clearance therebetween; and a pipe disconnection tool comprising: an insertion member comprising a plurality of parts and shaped to be positioned at least partially around and adjacent an exterior surface of said male end of said male pipe while said male pipe is connected to said female pipe; said insertion member having an inner wall, an outer wall opposite said inner wall, and an insertion length; said insertion member having a thickness between said inner wall and said outer wall which is less than or equal to said clearance between said male end of said male pipe and said female end of said female pipe; said insertion member having a leading edge at one end positioned around said male end of said male pipe, said leading edge forming an annular surface that is at least substantially continuous and disposed completely within a plane perpendicular to the longitudinal axis of said male pipe, wherein the plurality of parts are configured to converge to be contiguous at the leading edge; and at least one handle connected to said insertion member wherein said handle is positioned a longitudinal distance from said leading edge a distance equal to or greater than said insertion length, wherein said leading edge of said disconnection tool is completely removable from the clearance between said male end and said female end when said male pipe is connected to said female pipe, and wherein the pipe disconnection tool is configured to disconnect the male pipe and the female pipe from each other when the pipe disconnection tool is advanced along the longitudinal axis toward the female pipe, without need for rotation of the pipe disconnection tool about the longitudinal axis.
