Abstract: Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. The production of pipe bends with a supercritical bend of 0.7D, which form the part of serpentine systems, is very complex and technologically demanding, because very often undesired cracks occur. To increase the service life of these serpentine systems, the use of a 16Mo3 base steel pipe with a cladding layer of Inconel 625 material was proposed for their production in order to significantly increase their corrosion resistance. For this reason, an extensive analysis of the production of pipe bends with a supercritical bend of 0.7D from bimetal pipes with Inconel 625 cladding was performed, which addressed not only the bend but also the mechanical properties of the pipe with Inconel 625 cladding. It was found out that the production of the pipe bend with a bend of 0.7D of a bimetal pipe is feasible completely without defects with perfectly satisfactory mechanical properties.
