Analysis of Pipes

Pipes are fundamental for transporting fluids: fluids for cooling, feeding, and power among other things. However, pipes can experience problems of dynamics which can be destructive, and which were often not considered during design.

The difficulty in understanding these problems can be traced back to the frequency of forced stresses that can fatigue pipes. These frequencies can cause pipes to resonate, stressing natural frequencies, and impeding thermal displacement, vortex induced vibrations, overload, and high vibrations at pipe joints.

Currently, Vibro Technology has a range of tools that are capable of monitoring pipes in real time, which allows us to diagnose fundamental problems in pipes. The analysis of pipes depends on special sensors that are capable of resisting the constant variations of fluid dynamics and the impact that is generated inside of the pipe (the vibrations in the pipe can overload sensors used on conventional diagnostics). In addition, using a strain gage to measure strain allows us to determine tension in joints, fatigue, and overload.

Vibro Technology follows international norms in order to validate these analyses. Specifically, we follow “Allowable Piping Vibration Levels AMSE Paper 76-PET-18” and “ISO 10816-8:2014), which determine the permissible range of vibrations in pipes.  Furthermore, we use the Wohler curve in the analysis of fatigue and software for the dynamic analysis of stress in pipes.
