About TST Rohrtechnik
TST Rohrtechnik GmbH, based in Berlin, specializes in piping and plant construction and realizes projects in industrial as well as building services environments. The company masters all common welding processes – MAG, TIG and manual electrode welding – and complements these with mechanical joining techniques such as press-fitting systems and grooved couplings. The materials processed are primarily stainless steel and steel, for example for hygienic piping systems in the food and beverage industry or for welded joints on steam boilers, pressure vessels and turbines in power plant construction. Another focus is building services engineering: the company installs heating and refrigeration centers with complete piping. The fitters work nationwide, travel in company-owned vehicles and bring all tools and machines with them; all work equipment used is DGUV-tested. Reference projects include, among others, assignments for Lufthansa in Hamburg and the Klinikum Oldenburg hospital.
