Sikkerhetstrykk

Sikkerhetstrykk, often translated as safety pressure or set pressure, refers to the predetermined pressure at which a safety device, such as a safety valve or rupture disk, is designed to activate. This activation is intended to prevent over-pressurization in a system, which could lead to equipment damage, leaks, or potentially catastrophic failures. The safety pressure is a critical parameter in the design and operation of pressurized vessels, pipelines, and other equipment. It is typically set below the maximum allowable working pressure (MAWP) of the equipment to provide a margin of safety.

The determination of the correct safety pressure involves a careful analysis of various factors, including the system's operating conditions, potential upset conditions, and the properties of the contained fluids. Standards and regulations often dictate the minimum requirements for setting safety pressures. When the system pressure reaches or exceeds the safety pressure, the safety device opens or ruptures, releasing excess pressure and returning the system to a safe state. This automatic action is crucial for protecting personnel, the environment, and valuable assets from the dangers associated with over-pressurization. Regular testing and calibration of safety devices are essential to ensure they will function correctly at their designated safety pressure.
