Abstract

A method of lining an outer pipe (12) with an inner flexibly resilient pipe (14) includes the steps of introducing fluid into a pressure chamber (60) to reduce the diameter of the inner pipe (14) as the inner pipe is pulled into the outer pipe (12); increasing the length of the pressure chamber (60) as the inner pipe (14) is pulled into the outer pipe (12) to maintain the diameter of the inner pipe (14) pulled into the outer pipe (12) in its reduced form; and reducing the pressure of the fluid in the pressure chamber (60) once the inner pipe (14) has been pulled into the outer pipe (12) to discharge the fluid from the pressure chamber (60) as the inner pipe (14) expands within the outer pipe (12) to line the outer pipe (12).
