Preliminary test and calculation
Components for steam boilers, pressure vessels and pipe installations must be subjected to a preliminary test prior to manufacture. This tests whether or not the components can withstand the envisaged operating conditions. To do so, calculations taken from national and international regulations are used or, in complicated cases, numerical calculating methods (Finite Element Method).Pressure vessels can also be calculated online on the Internet by the "click-and-calc" application.

Using modern measuring methods and processes we identify the actual operating loads and stresses. These are of help to the design engineer. In cases of damage they provide answers to questions concerning the causes and the true stresses as regards size, passage of time and frequency spectrum.

Our additional range of services:

• Creep strain measuring technology: utilisation of the residual life (e.g. pipe bends)
• Potential probe measuring technology: continued operation of structural components with cracks
• Long-term monitoring of pipelines

Fracture mechanics
Fracture mechanics are used to assess whether or not a structural component with a crack in it can still be used.

Power station technology
This field of work includes for example investigations of the residual life of power station components subjected to heavy stresses and simulation of the dynamic behaviour of installations.
