Tube, Pipe & Profile Forming worked example
Hydroforming Pressure with baseline internal forming pressure of 250 units: a worked example
This scenario runs the hydroforming pressure calculation on the strong side: baseline internal forming pressure of 250 units, with every other input held at its documented default. Use it when hydroforming pressure in tube, pipe and profile forming is being sized against an asset rating.
The inputs for this scenario
- Baseline internal forming pressure: 250 units (raised for this scenario; the documented default is 100)
- Pressure intensification factor for the part: 1.2 x (unchanged)
- Press cycle or fill time: 8 hr (unchanged)
Working through the calculation
- Applying the documented formula (Hydroforming Pressure load = input load × load factor) to the inputs above produces each figure below.
- At this operating point the engine returns 300 psi for total load, the number this scenario is built around.
- At this operating point the engine returns 37.5 psi / hr for hourly equivalent.
- At this operating point the engine returns 250 psi for input load.
- At this operating point the engine returns 1.2 x for load factor.
How this compares with the baseline
- Against the tool's baseline example, where baseline internal forming pressure sits at 100 units and the headline result is 120 psi, this scenario comes in 150% above the baseline at 300 psi.
- Use it during early process design to target intensifier pressure and to sanity-check that calibration pressure is reachable within the intended cycle time. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
