Burst Pressure Margin with hose burst pressure of 4,000 psi: a worked example

This worked example runs the burst pressure margin numbers for a tougher week than the baseline: hose burst pressure of 4,000 psi instead of the typical 8,000 psi. Check burst pressure margin for a hose or tubing assembly by comparing actual or rated burst pressure against the required minimum burst pressure.

The inputs for this scenario

  • Hose burst pressure (rated or tested): 4,000 psi (the input this scenario stresses; the baseline uses 8,000)
  • Minimum required burst pressure: 6,000 psi (held at the documented default)
  • Reference burst pressure: 6,000 psi (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Burst pressure margin = hose burst pressure - minimum required burst pressure.
  • Absolute margin works out to -2,000 psi at these inputs, and this is the headline figure for the scenario.
  • Burst pressure margin (psi) works out to -33.33 psi at these inputs.
  • Available amount works out to 4,000 value at these inputs.
  • Required amount works out to 6,000 value at these inputs.

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 200% below the baseline at -2,000 psi.
  • Use it during hose selection for a pressure circuit or when checking a tested lot against a required burst pressure spec. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
