Steam hose failures

In an elastomer hose application, dry saturated or superheated steam at or below the temperature rating of the hose is acceptable, though the hose will heat age over time. Wet saturated steam poses a more severe problem for rubber and other elastomers because the inner core will absorb water. This will cause the tube to swell and deteriorate faster. In some cases the action of trapped water turning into steam can physically tear the inner core, creating a phenomenon called ‘popcorning’. Steam hose failures are usually caused by heat which either softens or hardens the hose material over time.
