Rubber steam hoses are made of best rubber compounds (EPDM mainly) reinforced with textile or steel braid (or cord) depending on the working pressure. These hoses are designed for saturated steam with a maximum working pressure ranging from 6 up to 18 bar, maximum temperature from 160 °C up to 210°C, and in some cases for superheated steam up to 232°C. When used for hot water, the temperature of water must not exceed 90 – 100°C. Both superheated steam and hot water have more destructive impact on the hose, even at lower pressure and temperature, than constant operation in a saturated steam application.
The rubber steam hoses are used in various industrial steam heating systems, process steam systems and for steam cleaning. The hoses can only be safely used if mounted with special steam fittings.
