METHOD FOR PRODUCING A MULTI-LAYER PIPE LINE, PIPE LINE, AND AIR-CONDITIONING SYSTEM HAVING SUCH A PIPE LINE

摘要

A method for producing a multilayered pipe line, in particular for transporting refrigerant in an air-conditioning system. First, an endless inner layer made of stainless steel having a layer thickness of at most 1 mm, preferably at most 0.5 mm, is provided, which constitutes the inside layer of the pipe line. Then, the endless inner layer is covered, by means of an extrusion process, with a plastic layer that preferably has a layer thickness of at most 7 mm, in particular at most 5 mm.
