Latest Patents

Wickman's latest inventions include a patent for a **Tube and a Method of Manufacturing a Tube**, which describes a high-temperature iron-chromium-aluminium (FeCrAl) alloy tube. This tube is intricately designed to extend along a longitudinal axis and is created from a continuous strip of high-temperature FeCrAl alloy featuring a helical welded seam. The innovative manufacturing method involves feeding the continuous strip into a tube shaping station, where it is helically wound, allowing the long edges to abut and then be joined through an immediate welding process, resulting in a robust welded tube.

Additionally, he has developed a **Method for Straightening of a FeCrAl Alloy Tube**. This method addresses the challenges faced when cold working ferritic FeCrAl-all alloys, which have low ductility. Wickman's technique involves heating the problematic tubes and utilizing a straightening and forming process through stretching, thereby overcoming deformation during the annealing process.
