Common Stress Concepts

Standard atmospheric pressure: 101.325kPa

Local atmospheric pressure: the actual local atmospheric pressure, generally between 90-120kPa

Absolute pressure:the pressure of absolute vacuum, it is absolute pressure 0

Gauge Pressure:The pressure value relative to the local atmospheric pressure.Generally, no special instructions are given, and the marked pressures are gauge pressures.

Absolute pressure:Pressure value relative to absolute pressure.Generally used in the measurement of vacuum degree.

Differential Pressure:The pressure difference between two pressures.Generally used for pressure comparison between two tanks or pipelines
