Does the maximum working pressure of heated hoses change with temperature?
Yes. Each heated hose, depending on the material it is made of, has pressure correction factors that must be taken into account in the calculations. For example, a PTFE hose with a diameter of 8 mm, which has a maximum working pressure of 200 bar at room temperature, will operate at a maximum of 166 bar at +250°C (correction factor 0.83).
