Abstract

Aluminum CNG vessels compared with steel ones can lead to lower fuel consumption. Dome forming (spinning) is an important step in seamless CNG vessels fabrication. This paper aims to the process simulation on a 6061-O aluminum tube at an elevated temperature, investigation of feed effect on the stress and strain after the first pass and its effect on the whole of the process. After the whole process simulation and achievement of the final dome shape, to investigate the feed effect on the strain, circumferential, axial and thickness strains after the first pass, on different inner, middle and outer paths of the tube wall are reported in some figures. Feed variation has not a considerable effect on the decrease of increase rate of circumferential strain absolute value and on the strain distribution on the middle path. The primary higher feeds effect on other investigated strains is smoother distribution. This effect is in agreement with a more stable process and less wrinkling at higher feeds. This stability is reported in a higher tested feed in this paper. On the other hand, investigating different feeds shows that the feed increase leads to decrease of maximum stress in the tube after roller separation at the end of the first pass.
