Abstract: Disclosed are methods and apparatuses for removing and/or installing valves located between two fixed pipe spool pieces. The valves can be located between first and second immovable pipe spool pieces having a fixed distance between the first and second immovable pipe spool pieces, and in the process of removal a gap is created between the first and second immovable pipe spool pieces. The immovable pipe spool pieces can have longitudinal axes which are parallel, and the gap created along a longitudinal line which is parallel to the two longitudinal axes of the pipe spool pieces. The longitudinal axes of the first and second pipe spool pieces can be coincident with each other.
