Types of Pressure Vessels

Two Basic Types of Pressure Vessels Based on Wall Thickness?

Thinned wall -These pressure vessels are the most categorized. A thinned walled pressure vessel is any cylinder [shell] ratio that is 10% or less the ratio of the thickness to the diameter. Another way of saying this is a pressure vessel is thinned walled if the diameter is 10-times or more the thickness.

  t   < 0.1

Thick walled -These pressure vessels are the least common. A thick walled pressure vessel is any cylinder [shell] ratio that is 10% or more the ratio of the thickness to the inside diameter.

  t   > 0.1

Storage tanks -Storage tanks are a category of thin walled pressure vessels except that are typically under 15-psi and are super thin when compared to the ratio above.Transportable Containers -These are the most common pressure vessel and potentially the most ignored.  These are mass produced and require testing every 10-years for propane and gas.

Propane bottles - Fork trucks, barbecues,Gas cylinders - CO2, O2,...

Other - Containers, gas cans, bubblers,...
