Oxygen Gas Cylinder – It is a seamless steel container used to store oxygen gas safely and in a large quantity under a maximum pressure of 150 kg/cm2  (2100 PSI).It is used for gas welding and cutting. ( 1 Kg/cm2 =14 PSI)

It is made from seamless drawn steel and tested with a water pressure of 225 kg/cm2(3150 PSI). The cylinder top is fitted with a high pressure valve made from high quality forged bronze. The cylinder valve incorporates a pressure safety device, which consists of a pressure disc, which will burst before the inside cylinder pressure becomes high enough to rupture the cylinder body. The cylinder valve outlet socket fitting has right hand thread, to which pressure regulator is fitted. The cylinder valve is also fitted with a steel spindle to operate the valve for opening and closing. A steel cap is screwed over the valve to protect it from damage during transportation.

The cylinder body is painted black and the valve outlet is screwed right hand. The capacity of the cylinder may be 3.5m3-8.5m3. Oxygen cylinders of 7m3 capacity are commonly used. The oxygen cylinders are filled with oxygen gas under a pressure of 120-150kg/cm2 (1680-2100PSI). The cylinders are tested regularly and periodically. The wall thickness of the cylinder is 6.5mm.
