Steam Hose

Steam rubber hose is mainly designed to transport high temperature, high pressure steam or hot water, its typical application includes: industrial hot pressing equipment, steam cleaning, food and dairy processing, industrial heating systems etc. The main reason why steam rubber hose can withstand high temperatures is that its inner and outer rubber layers are all made of EPDM material. EPDM is famous for its strong high temperature resistance performance even up to 150-220, while natural rubber generally below 100. Its middle pressure bearing layer  always made of woven or wound steel wire, which enable it both heat-resistant and pressure-resistant.

Steam rubber hose is constructed of 3 composite layers:
