In various fields of engineering, the assembly and repair of hydraulic installations are accomplished by joining the pipes. In such applications, the ring swaging method is used to connect the fittings to the pipes by means of a hydraulic hand tool. The basis to develop a swaging tool relies on the knowledge of the design parameter that influence plastic deformation of the swaging ring. In addition to build control over the design parameters, it is necessary to join pipes under severe conditions such as cryogenic vacuum and constrained space which require an intact sealing. In this study, the effect of swaging ring designs on sealing and strength has been examined and different swaging methods have been investigated by finite element modeling methods. Based on the obtained results, the analysis methodology of ring swaging and the characteristic impact of swaging ring design on the sealing of pipe connection are shown. The prime novelty of the study is to report the impact of swaging ring design and geometry on sealing efficiency of the pipe connection. The results of the study open new avenues for the development of efficient tools for designing swaging rings. Doi: 10.28991/cej-2021-03091641 Full Text: PDF

Design affects the entire lifespan of a product. Humans design ideas in their environments, especially to meet their own needs. People come to design ideas and abilities from various objects and events in nature, and use these to increase their design capabilities. With the increase in human population, proliferation of product needs, and the dangerous use of products, the ethical risks have increased. The risks within unethical designs have now reached all levels of human life. Products have been introduced to the market without considering their ethics, and in many of them, only the material purpose has been pursued, instead of the benefit to humanity. This research focused on the goal of the product designers, which is to design and develop a product, while contributing to the awareness that the product needs to be subjected to both risk and ethical analyses as with all other requirements. The dominant task of this study is to enable designers and their designs to develop their own ethical discourse and concepts. In doing so, the most forward aim is to not damage humans, but to design what is useful. The impact on the designer is to have ethical responsibility for their designs.
