Experimental stand for internal pressure testing of pipes

Abstract

The experimental programs carried out on the stands for the research of mechanical stress behaviour typically target the following objectives: to determine the behaviour of the pipes at internal pressure and / or other mechanical stresses (which may secondary occur as accidental loads during exploitation), to establish the processes and factors of in-service degradation and to determine the load carrying capacity of pipes and other components of pipelines systems with defects of different types and configurations. For this paper an experimental stand was designed and developed for the purpose of determining the behaviour of the pipes with different types of imperfections / defects. The experimental results were verified and validated using the finite element method.
