Original abstract

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. They are made by welding resistive material to commonly available carbon steel pipes. The production of pipe bends with a supercritical bend of 0.7D, which are 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 that the production of the bent pipes with a bend of 0.7D is feasible completely without defects with perfectly satisfactory mechanical properties, under appropriate technological conditions.
