Vessel Heads Are Very Varied Used In Candle Holders To Pipe End-pieces Or Pressure Vessels In Equipment Construction.
A vessel head is a component that seals the end of a pressure vessel. these components, also known as end caps or dish ends, are crucial for the safe and reliable operation of industrial equipment by containing fluids and gases under pressure. different shapes exist, such as hemispherical, elliptical, and torispherical heads, each with varying strengths and applications depending on pressure requirements and manufacturing costs.
Cost-effective, used in low-pressure vessels.
Common above 10 bar, smooth stress transition, deeper profile.
Easier to manufacture, widely used in large-diameter vessels.
Strongest design, requires half the wall thickness of shell.
Vessel heads are the end caps on cylindrical pressure vessels that seal the containers to prevent the escape of internal gases or fluids and to withstand internal pressure.
They come in various shapes, such as hemispherical, ellipsoidal, and torispherical, with the choice of head depending on factors like the pressure, cost, and application. Vessel heads are critical for the safety and structural integrity of pressure vessels used in industries from oil and gas to medicine.
| Head Type | Strength | Manufacturing | Applications |
|---|---|---|---|
| Flat | Low | Simple & Cheap | Low-pressure storage |
| Ellipsoidal | Medium-High | Moderate | >10 bar, chemical & oil industries |
| Torispherical | Medium | Easy | Large-diameter pressure vessels |
| Hemispherical | Highest | Complex | High-pressure reactors, gas storage |
