Latest Patents

Marion holds a patent for a "Method for the production of hot-finished seamless pipes having optimized fatigue properties in the welded state." This invention relates to a method for producing hot-finished, particularly hot-rolled, seamless pipes with an outside diameter of up to 711 mm and a nominal wall thickness of up to 100 mm, primarily made of steel. The method involves creating a defined pipe cross-section at one end of the pipe, ensuring tight tolerances for both inside and outside diameters. The process includes a two-step approach where the wall thickness is first increased at the pipe end, followed by mechanical treatment to achieve the required cross-section with low surface roughness and minimal notches.
