Training Course:

Qualification of Personnel Competency in the Assembly of Bolted Flanged Joints according to the European standard EN1591-4

See Dates for the 1-day training course listed below

training course for assembly: EN 1591-4

The training course and the examination of the qualification of assembly personnel is based on the curriculum defined in the European standard EN 1591-4:2013.

The training plan is divided in 3 sections with theoretical and practical units based on practical application. AMTEC has been playing an active role in developing techniques to understand root causes for leakages and find out how to achieve leak-free joints for more than 15 years now. Gasket testing, calculation and assembly procedures as well as measurement techniques have been developped for the nuclear industry first. Then it turned out that the optimized procedures can easily applied to chemical and petrochemical plants.

We impart our comprehensive knowledge and hands-on experience to the participants of this training.

In realistic exercises the bolt forces during assembly are monitored and displayed online in order to experience the influence of different parameters such as tightening technique, friction, surface quality, ...
