Project Partnership

We run two internships for academics from the Warsaw University of Technology within the framework of TEKLA PLUS www.teklaplus.pl programme, co-funded from the European Social Fund. Both internships are part of our R&D works aimed at designing and producing robots for non-destructive tests automatisation.

We can also become partners in your project.

THE METHODOLOGY OF CHARACTERISATION, IN A REAL STATE OF DEGRADATION, OF THE MATERIAL AND WELDED JOINTS OF PRESSURISED TECHNOLOGICAL PIPELINES FOR TRANSPORTING CHEMICAL SUBSTANCES OF TEMPERATURES BELOW MINUS 100°C, USING ACOUSTIC EMISSION METHOD

Service loads on pipelines for transporting chemical substances of temperatures below minus 100°C generate defects of the structural material and welded joints in the form of surface losses and discontinuities of the structure in the volume of the material. When critical values are reached, such defects may lead to an uncontrolled destruction of the facility and pose a threat to the technical and economic safety of the technological process and the environment. The effect of the research will consist in providing a methodical solution allowing to determine the fatigue characteristic and to evaluate the degree of destruction of the material in a real state of operational degradation. The purpose of the project is to create a solution enabling methodical diagnostic testing in a real state of operation by means of a research technique using the acoustic emission (AE) phenomenon as the leading method. The features of this method and the wide range of equipment that may be used allow for detecting, localizing and identifying active defects in the entire volume of the material used for the construction of a pipeline. Such an approach to the problem of safety differs fundamentally from the solutions currently applied in the industry, i.e. the ultrasonic method, eddy currents, modal or radiographic analysis etc. These techniques will also be applied in the project for a detailed characterisation of the geometry of the defect that will evolve to predominating size in function of the time passed.
