Components of a Pressure Vessel

Pressure vessel consists of different components. As per ASME Section VIII Div. 1 following are the components of pressure vessels:

1. Dish Heads or Heads
2. Shell
3. Reducers or Cones
4. Nozzles
5. Skirt
6. Attachments like Saddle supports, Skirt support, Leg supports, Trunnions lifting Lugs, Platform supports, Ladder supports, Stiffener Rings etc.

Here note that manufacturing of dish heads & cones is difficult than other components as dimensional control is critical during the manufacturing of these items. Hence these items should be manufactured first.
