About Schwarz & Schmidhofer Industrial Plant Construction
Schwarz & Schmidhofer Industrieanlagenbau GmbH has been active in piping construction, steel construction, and industrial assembly since 1987, and is based in Frankenthal (Pfalz). The range of services extends from the planning and prefabrication of pipe parts (spools) to welding (WIG, MIG, MAG, E-Hand, WIG-Orbital), plant assembly, commissioning assistance, corrosion protection, and insulation. The company manufactures pipe parts, pipe bends, and welded steel components such as pipe bridges, support structures, pipe hangers, operator platforms, ladders, and railings in its own operation. High- and alloy steels (notably 16Mo3, 13CrMo 4-5, P91, P92), stainless steels (1.4301 to 1.4591, Duplex 1.4662), nickel alloys (Alloy 201, 400, 800), titanium, and plastics are processed. Customers primarily come from chemical, petrochemical, energy and environmental technology, power plant and CHP construction, and the wood industry. The company is certified according to ISO 9001:2015 and SCC** 2011 and implements projects in Germany and across Europe, including French overseas departments.
