Analysis of bimetal pipe bends with a bend of 0.7D with a cladding layer of Inconel 625

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