Method of removing the contents from a pipe (1 ) comprising forcing a gas flow through the pipe, the pipe having a pipe volume, an inlet end and an o utlet end (9), characterized in that the gas flow is forced into the pipe (1 ) at the inlet end by applying a gas pressure decreasing from an initial pr essure to a lower final pressure to remove at least parts of the contents fr om the pipe and maintaining that lower final pressure to remove the remainin g contents from the pipe and apparatus for removing the contents from a pipe by forcing a gas flow through a pipe (1 ) having an inlet end and an outlet end (9), comprising gas flow generating means (5) and a container (3) havin g an inlet and having an outlet connectable to the inlet end of the pipe (1 ).
