DEFINITION OF THE PRETENSIONING OF THE TUBES WHEN WINDING A TUBE BUNDLE OF A COIL-WOUND HEAT EXCHANGER

摘要

The invention relates to a method for winding at least one tube (20) onto a core tube (21) of a coil-wound heat exchanger (1), wherein the at least one tube (20) is wound helically onto the core tube (21), in that the core tube (21) is rotated about its longitudinal axis (z), wherein, while being wound onto the core tube (21), the at least one tube (20) is continuously pressed with a momentary pressing force (F_A) against the core tube (21) or against spacers (6) that have been fixed in advance on a layer of tubes (200) already wound onto the core tube (21), wherein the momentary pressing force (F_A) during the winding on of the at least one tube (20) is controlled in an open-loop or closed-loop manner. The invention also relates to a corresponding device (30) for carrying out the method.
