A further patent application for the atrac® system has now been published: DE 10 2023 001 951 describes the automatically adapting local wall thickness control atrac® smart LTC. This wall thickness control compensates for recurring wall thickness deviations from pipe to pipe over the length of the pipe and only requires the online wall thickness measurement on the outlet side. Important: Any reduction in wall thickness deviations can be used to save on the feedstock and in further processing. This is a clear competitive advantage when using the atrac® system.
