about us

"Quality - Made in Germany" is what Hermann Rosorius Ingenieurbüro GmbH has been all about since its earliest days in 1949. The sophisticated range of external- and internal centring tools for welding technology in conduit-, system- and tank construction offers the user a quick, accurate and above all safe method for aligning pipes and flanges. Practical aids such as flange levels and tilt levels, centre punches or special models for orbital welding complete the product range.
