Metal Hose Temperature Factors & Conversions

The strength of metal alloys decreases as internal or external temperature increases. Maximum allowable working pressures of metal hose will decrease when temperatures increase.

The pressure ratings shown in the Metal Hose Online specification tables for hose are valid at 70°F. Higher operating temperatures will decrease these pressure ratings by the factors shown in the chart below for the alloy used in the braid wire.

The maximum working temperature of the end fittings, the corrugated hose, and their method of attachment must also be considered.

For example, to calculate the maximum working pressure for 1” ID Braided Metal Hose 321 stainless steel corrugated hose With single-braided, 304L braid At 700°F.

From the braided metal hose specification table, the maximum working pressure at 70°F is 571 PSIG. Multiply 571 PSIG by 0.74. The maximum working pressure at 700°F is 422 PSIG.
