PRESSURE VESSEL
A pressure vessel is a type of unit. It is one of the most important components in industrial and petrochemical process plants. In the broad sense, the term pressure vessel encompasses a wide range of unit like heat exchangers, reactors, storage vessels, columns, separation vessels, etc.
The design procedure is set according to the operational requirements. These are imposed on the vessel as part of the overall plant and include the following:
- Operating Pressure
- Design Pressure
- Operating Temperature
- Design Temperature
- Fluid Conditions
- External loads
The functional requirements are based on the geometrical parameters & include following:
- Size & Shape of the vessel
- Method/Type of vessel support
- Location & size of attachements & nozzles
Before manufacturing the complete drawing of the vessel is submitted for approval with following details:
- Design conditions
- Welding procedures
- Key weld details
- Heat treatment procedures to be applied
- Non-destructive test requirements
