Title: Johann Wassen: Innovator in Tube Measurement and Production
Introduction
Johann Wassen is a notable inventor based in Brackwede, Germany. He has made significant contributions to the field of tube measurement and production, holding a total of four patents. His innovative methods and apparatuses have advanced the precision and efficiency of tube manufacturing processes.
Latest Patents
One of Wassen's latest patents is a method and apparatus for measuring the wall thickness of a tube. This method involves axially introducing a radioactive radiation source into the tube and directing its radiation at approximately 45 degrees toward the tube wall. The process includes distributing multiple scintillation counters uniformly around the tube and measuring the transmitted radiation. The measurement values are compensated for specific wall thicknesses and amplified proportionally to the radiation intensity. These values are adapted to be fed through a measuring capacitor, with the charge values indicated in succession and processed by a statistical measurement value detecting arrangement. Additionally, the measuring arrangement is automatically calibrated by introducing the radiation source into a standard dimension tube for accurate measurements.
Another significant patent is a continuous process for producing very long precision tubes. This novel method and apparatus allow for the continuous formation of a long tube with precise internal and external dimensions from a metal tube blank. The internal diameter of the blank is reduced to that of an internal mandrel, preferably through cold forming, followed by drawing the tube to its final external dimension without any annealing between the two steps.
