Abstract

A method for producing a pre-insulated pipe, comprising inserting a length of jacket pipe () into a guide channel () having a front end () and a rear end (); fixing said length of jacket pipe () in said guide channel (); providing a first end () of a length of insulated inner piping (), said length of insulated inner piping comprising a length of inner pipe surrounded by at least one layer of compressible insulation material (); inserting, at said front end of said guide channel, into said length of jacket pipe, said first end of said length of insulated inner piping (); applying an overpressure at least in an interior of said length of jacket pipe (), around the inserted first end of the length of insulated inner piping (); and moving said first end of said length of insulated inner piping () to said rear end of said guide channel (); wherein said overpressure is such that said at least one layer of insulation material () is radially compressed; removing said overpressure to fix said length of insulated inner piping () in said length of jacket pipe () in order to form a pre-insulated pipe.
