Tube, Pipe & Profile Forming worked example

Leak Test Capacity at 99% leak-test station uptime: a worked example in tube, pipe & profile forming

Push leak-test station uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when leak test capacity in tube, pipe and profile forming is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Tubes leak-tested per cycle: 4 units / cycle (unchanged)
  • Available leak-test cycles: 480 cycles (unchanged)
  • Leak-test station uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass leak-test yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross leak test capacity capacity = units per cycle × available cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross capacity.
  • At this operating point the engine returns 19.2 units for uptime loss.
  • At this operating point the engine returns 57.02 units for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where leak-test station uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It computes good output capacity as units per cycle times available cycles times uptime times yield, and breaks out the units lost to uptime and to yield separately. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Good output capacity: 1,844 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units
