Design Examination

TÜV NORD’s Engineering Verification Group (EVG) is presently one of the leading design examination service provider for the mechanical engineering sector, with enhanced expertise in pressure equipment / component design verification.

EVG’s competencies are derived from a tradition established in Germany around 140 years ago. Our special concern has always been and one that still continues to remain is the constant improvement of our work ethics, processes and quality mechanisms to ensure protection of people, property and environment from the hazards and detrimental effects of technology.

Personnel & quality system at EVG are rigorously scrutinized and continuously monitored by our parent company in Germany to ensure that only the highest level of service is delivered to our patrons.

EVG engineers have in-house expertise to perform simulation for all components of critical pressure equipment such as multi-wall reactor vessels, irregular shaped pressure vessels, large openings on vessels with pressure + external loadings, etc using commercial Finite Element Analysis solvers and in-house computer software DIMY developed by TÜV NORD, Germany EVG engineers routinely perform design by analysis simulations to a variety of international codes & standards such as:

• AD2000 Markblatter
• ASME Section III
• ASME Section VIII, Div.2 & Div.3
• PD 5500
• EN13445
• TEMA
