Plastic Components in Plant Engineering – Demanding Materials require Expert Knowledge

Sometimes visible at first glance, sometimes well hidden: plastics can be found in countless products today – in everyday life as well as the industry. This is because they are versatile, resistant and durable.

The material also plays a major role in plant engineering. Here, for example, plastics are increasingly used for containers or piping systems. Particularly where these components are relevant to safety, it is essential, of course, to ensure their functionality at all times in advance – even under special loads.

Due to their complex material behavior depending on many different factors, plastics require special know-how and comprehensive experience for component simulation. For many years now, we have been performing the following tasks for our customers:


By means of finite element analysis, we reconstruct the damage origin, identify weak spots and develop recommendations for improvement.


In civil and plant engineering, safety-related plastic parts require an inspection and certification. Necessary analysis can be carried out by Wölfel. This includes, among other things, mathematical verifications of the load-bearing capacity and serviceability of separator systems for light liquids and greases according to DIN 19901. Our close cooperation with inspection and licensing authorities facilitates the approval procedure.


Typical load cases for plastic components

  • Dead load
  • Internal pressure
  • Temperature

  • Live load

  • Earth thrust
  • Ground water
  • Chemical effects
  • Wind and snow

Operating and special loads: our areas of expertise


Whether in the context of new constructions, conversions or retrofits: we support plant manufacturers and operators in the design of entire plants or individual components in all structural-mechanical issues. Due to our expertise built up over many years, we are particularly consulted for the following load cases:
