Answer:
Oxygen and other gases were compressed and stored at high pressure in seamless containers constructed from hand-forged steel in1880. Materials technology has continued to evolve and now medical gas cylinders are generally made of steel alloys or aluminum.
Formation of the cylinder:-
1 Oxygen tanks are manufactured from a single sheet of 6061 aluminum. The starting material is called a cast billet, which is approximately 18 ft (5.5 m) long and shaped like a log...
2 The cast billet is placed on a conveyor belt and cut to the desired size by an automated saw. The sawn piece is called a slug and is almost the same weight and diameter as the finished product....
3 The slug is then placed inside a die in a backward extrusion press. The press forces a punch against the slug. The metal of the slug flows backwards around the punch forming a large, hollow, cup-shaped product called a shell...
4 The shell is then inspected for defects and gauged....
5 Next, the shell is put through a process called swaging. The open end of the shell is heated and forced into a closing die to close the open end of the cup. Now the general shape of a seamless cylinder is finished...
