Abstract
Summary
This paper covers the theoretical and practical evaluation of straining which arise due
to stressing, and plastic deformation during the deep drawing process of the production of
the shells for LPG cylinders, as well as the process description and application. Therefore
the study includes experimental work in the field of metal drawing in stages for different
depths 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 of
metal used in producing the domestic LPG cylinder were heat treated in different situations
to study the influence of an annealing operation on the metal (its microstructure,
metallurgical, and mechanical properties
