Theoretical and Practical Evaluation of Plastic Deformation and Straining Throughout Cupping the Shells of Domestic LPG Cylinders

Abstract

SummaryThis paper covers the theoretical and practical evaluation of straining which arise dueto stressing, and plastic deformation during the deep drawing process of the production ofthe shells for LPG cylinders, as well as the process description and application. Thereforethe study includes experimental work in the field of metal drawing in stages for differentdepths to tabulate the radial metal movement and changes in shell thickness and diameter.As the annealing treatment has an important role in the production sequence, so samples ofmetal used in producing the domestic LPG cylinder were heat treated in different situationsto study the influence of an annealing operation on the metal (its microstructure,metallurgical, and mechanical properties
