Latest Patents
One of Ramdohr's latest patents is a process and device for producing pipes according to the UOE process. This invention focuses on the production of large pipes, where the pipes undergo internal and external seam welding before being incrementally calibrated by cold expansion up to half their length. The cold expansion technique is also utilized for straightening the pipes. The process involves clamping the pipe at a minimal distance in front of the expander head, flexibly deforming the free pipe end, and then cold expanding the pipe in a known manner. As the prestress force decreases, the pipe moves incrementally by the expander step width, and this process is repeated for the second half of the pipe.
