Rosswag now TÜV SÜD certified for Additive Manufacturing of pressure equipment
April 21, 2023

Rosswag Engineering, Pfinztal, Germany, has been certified by TÜV SÜD for the Additive Manufacturing of components made of 316L stainless steel (1.4404) according to the European PED (Pressure Equipment Directive) 2014/68/EU.
Rosswag Engineering is one of the first manufacturers in the world to gain this certification, and to achieve this, the company completed the extensive testing and certification programme in accordance with DIN 17026:2020. Essentially, the quality of the entire process is certified – from the consistency of the manufacturing processes to the internal processes for quality assurance and quality controls to the reproducibility of the mechanical-technological properties, considering the PED requirements.
In order to meet the high quality demands of additively manufactured pressure equipment, more than 100 specimens were produced on the SLM® 280 2.0 Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machine and subsequently tested.
“We want to offer solutions to transfer more functional optimised and additive manufactured components into industrial applications,” stated Gregor Graf, Head of Engineering at Rosswag GmbH. “But to be able to apply innovative heat exchangers, for example, there was no alternative to certification according to the Pressure Equipment Directive.”
Gunther Kuhn, Head of Product Management at TÜV SÜD Industry Service GmbH, added, “With our certification according to the Pressure Equipment Directive, we can also confirm the high quality, reliability and safety of Rosswag GmbH’s additive manufactured products for the end user.”
