Burst Pressure Margin with hose burst pressure of 20,000 psi: a worked example

What does the result look like when hose burst pressure reaches 20,000 psi? The full calculation is worked below with real intermediate numbers. Use it when reviewing hose assembly qualification data, comparing hose specifications, or confirming a hose meets the required safety factor over working pressure.

The inputs for this scenario

  • Hose burst pressure (rated or tested): 20,000 psi (raised for this scenario; the documented default is 8,000)
  • Minimum required burst pressure: 6,000 psi (unchanged)
  • Reference burst pressure: 6,000 psi (unchanged)

Working through the calculation

  • Applying the documented formula (Burst pressure margin = hose burst pressure - minimum required burst pressure) to the inputs above produces each figure below.
  • At this operating point the engine returns 14,000 psi for absolute margin, the number this scenario is built around.
  • At this operating point the engine returns 233 psi for burst pressure margin (psi).
  • At this operating point the engine returns 20,000 value for available amount.
  • At this operating point the engine returns 6,000 value for required amount.

How this compares with the baseline

  • Against the tool's baseline example, where hose burst pressure sits at 8,000 psi and the headline result is 2,000 psi, this scenario comes in 600% above the baseline at 14,000 psi.
  • A figure at this level is achievable when hose burst pressure is genuinely sustained, not just peaked for a shift. Burst margin alone doesn't cover fatigue from pressure cycling, temperature derating, or fitting retention, which often govern real service life more than a single burst number.
