  • For static pipe work, the bend radius can be reduced considerably.
  • For extra high pressure, extra braid can be provided. Consult our Technical Department.
  • For pressure drop estimates of corrugated metal hose, consult our Technical Department.
  • The above pressure ratings are for fluid at ambient temp. of 30°C.

Temperature

As the operating temperature of a hose assembly increases, the maximum working pressure of the assembly decreases.

How to use Temperature Corrections Factor Chart?

  • Determine the maximum operating temperature of the application.
  • Locate this temperature on the chart and read across to the proper factor.
  • Multiply this factor times the maximum working pressure as determined from the Hose Specification Chart.
  • This answer is your maximum Safe Working Pressure at that Elevated Temperature.
