Abstract

A heatable medium pipe having at least one pipe connector and heating element, wherein the heating element has a few wires, in particular two wires, and said wires extend continuously along the medium pipe and along the at least one pipe connector. In a method for producing such a heatable medium pipe, the heating element is continuously wound around a tubular medium pipe and the heating element is pre-assembled on the medium pipe in that the heating element is fastened or fixed by at least one fastening element, the medium pipe is cut to a first length for the particular application, the length corresponding to the desired medium pipe length (lR) plus the heating element length (lH) required for wrapping around the at least one pipe connector and the transition area the fastening element is removed in the region outside the desired medium pipe length (lR), the heating element is unwrapped from the medium pipe section cut from the first length, the medium pipe is cut to the desired medium pipe length (lR) to form a second medium pipe section, the medium pipe section is connected to the at least one pipe connector as the medium pipe, and the heating element is at least wrapped aroun…
