I've entered details for the above pictured PVC pipe under pressure and got 15psi. Sounds about right. If it's indeed used with 40psi that'd explain the severely swollen shape. Still well below burst pressure and it will survive for some time.

On the shown image around 1.023. However that's a great question indeed... After all it bursts at 1.0008.... so that should be the bursting pressure 🤔 Here it shows a different curve with bursting pressure going off the chart.

I guess it's the same effect as with inflating balloon with gradually increasing pressure (see the picture). Unless I'm (and Wikipedia is) mistaken Vynil == PVC (when talking about pipes). It could be coloured or clear, harder or softer, with or without additions. Could also be pressure rated...

Are yours 1mm ID / 4mm OD or significantly different? Then I guess working pressure should be, say, 1/10 of the burst pressure as a safety measure.

Thank you, corrected the psi figure above. I'm using the formula from the link above. Do you think it's wrong?

Thank you both. According to the formula in the link burst pressure should be around 70 bar (1000 psi) for my pipe. For the 1" PVC pipe in the picture it should be around 20 bar (300 psi). (corrected the number, thank you)

What maximum pressure this silicon pipe would withstand until blowing up? ID=1mm, OD=4mm, no cord or anything like that in the pipe, pure clear silicon.
