Apparatus Fabrication

High-pressure apparatuses of carbon steel alloy. Pressure vessels made of CrNi steels for corrosive processes. Welding constructions weighing tonnes for very high loads. All this with unexampled precision, made possible by one of the most modern machine parks in Europe. Spatially strictly separated, we work the very latest materials from plant construction. For CrNi and Nibas steels, one of the biggest pickling plants in Austria takes care of the perfect finish. The high quality is assured by our certifications and the in-house NDT department with state-of-the-art testing equipment.

Perfect support and complete solutions for your process. Our engineering seamlessly joins the basic engineering of the process provider and the customer. Consultancy, development, analytical and FE stress calculations, heat technology designs, detail engineering and welding technology are carried out directly by our technology sections.
