Engineering Logic of Working Pressure, Burst Pressure, and Safety Factor
This article outlines the engineering logic behind working pressure, burst pressure, and safety factor in hydraulic hose applications. It explains how working pressure defines the maximum continuous operating limit, while burst pressure represents the structural failure threshold verified under laboratory testing. The safety factor, commonly expressed as a ratio between burst and working pressure, serves as a controlled margin to manage operational risks and material variability. The discussion emphasizes that proper hose selection should not rely solely on nominal ratings, but instead consider peak pressure spikes, impulse frequency, and real operating conditions. By clarifying the relationship between these three parameters, the article highlights the importance of matching hose structure to system load in order to ensure long-term hydraulic performance and operational safety.
