Jacketed Loading And Unloading Hoses Bulk storage and distribution centers for molten products such as bitumens, hot melts, pre-polymers, and sulfur are typical applications for jacketed loading and unloading hoses. The construction of the hose assembly consists of a flexible core and a flexible jacket. End connections may be of any type or style compatible with the connectors of mating equipment. If the jacketed hose is the last assembly in a steam-heated equipment train -- as on the end of a loading arm, for example -- the steam supply and condensate drainage need close scrutiny. Other points to consider: Insulation and personnel-protection requirements, protection from mechanical damage, operational procedures to prevent process damage, personnel weightlifting restrictions, and hose flexibility requirements. CSI sales personnel can help you make optimum selections to meet various operating conditions. Hose constructions vary widely. The core hose material usually is dictated by the process. Type 321 stainless steel is a common (and least expensive) material. Type 316/316L stainless steel is often used. Note, however, that an aggressive processes or unusual conditions of operation may dictate the use of higher alloy materials such as Monel* or Hastelloy*. The standard CSI braid material of the core hose is Type 304 stainless steel. The standard CSI jacket hose material is Type 321 stainless steel with Type 304 stainless steel braid sleeve. Where aggressive plant atmospheres attack Type 321 and 304 stainless, Type 316/316L hose and braid materials are offered. Maximum allowable working pressures for jacketed hoses vary with diameter, temperature and braid configurations (single braided or double braided). * Trademarks
