Industrial Applications of Pressure Vessels

• Chemical industry• Cosmetics processing• Food and beverage industry • Oil / fuel industry• Paper and pulp industry• Pharmaceutical and plastic processing• Power generation

• Welding• Compressed Natural Gas (CNG ) Cars• Scuba• Search and Rescue (SAR)

Other Applications of Pressure Vessels

Types of Pressure Vessel

• By geometry and size:– Spherical Pressure Vessel– Cylindrical Pressure Vessel– Other shapes

Types of Gas Cylinders:

• By material:– Fully metal Gas Cylinders– Hoop Wrapped Gas Cylinders– Fully wrapped Gas Cylinders– All-composite Gas Cylinders

Types of Gas Cylinders:

• By pressure:

– Low pressure P<20 [bar] – Middle pressure 20<P<65 [bar]– High pressure P>65 [bar]

1 [bar] = 0.9869 [atm]
