Temperature Adjustment Factors
To use the calculator, please view this page on a desktop computer or on "Desktop Mode" if using a mobile device.
In general, as operating temperature increases, Maximum Allowable Working Pressure (MAWP) decreases. With elevated service temperatures, comes a need to adjust the pressure ratings of a metal hose assembly per the factors listed in the chart below. These factors are based on the braid wire alloy.
Temperature Adjustment Factors Based on Braid Alloy
The calculator below will help you find the MAWP of a certain hose assembly at a given elevated temperature.
Please note, calculator assumes 304/304L for P3, P4, 700, 800, 900, 1400 and P5 Series hoses; Monel 400 for Series 740; Hastelloy® C-276 for Series 776; Inconel® 625 for Series 625; and Bronze for Series 794.
