Overpressure

Overpressure is a physical quantity that describes the difference between the actual pressure in a system and the pressure that would be in the same system under normal conditions. It is the degree to which the pressure in the system is higher than normal atmospheric pressure.

Overpressure is often used in the context of enclosed spaces such as tanks, pipes, equipment or buildings where a higher pressure than the ambient atmospheric pressure is intentionally maintained. This can have various reasons and uses.

Overpressure can be created, for example, by means of compressors or pumps that supply air or liquids to a closed system. This increases the pressure inside the system above atmospheric pressure.

There are several reasons and uses of excess pressure. For example, in water supply systems, overpressure is created to get water to higher floors of a building. In industry, positive pressure is often used to enhance the flow of liquids or gas in pipes and piping systems. Overpressure is also used in various processes such as tire manufacturing, air engineering, chemical industry and others.

It is important to properly check and regulate overpressure to avoid too high a pressure that could lead to system damage or safety hazards. Therefore, valves, regulating elements and safety devices are often used in these systems, which keep the excess pressure within the specified limits and ensure safe operation.
