Abstract

A method of applying insulation continuously to pipes in a production line, where the pipes are heated, primed, and extruded, consists of fitting preformed segments of insulation around the pipe as it advances. Preferably, after the segments have been fitted, the continuous pipe passes through an extruder head, where an external plastics sleeve is formed around the insulation. The method is used in the mass production in the factory of insulated pipe for cooling plants, district heating systems, etc.
