We obtained certification under the European Pressure Equipment Directive (PED) 97/23/EC in June 2006 and established a management system for the design and manufacturing of pressure equipment for the European market. (Scope: Category II, Module D1)
We have also completed the transition to the 2014 version of the Directive, 2014/68/EU. This system covers all processes from pressure‑equipment design, materials management, welding, brazing, and through to pressure testing and leak testing, ensuring the safety of all pressure equipment manufactured under this system.
