A jacketed hose is a type of flexible hose assembly designed with two concentric hoses:
    •    Inner Hose (Core Hose): Carries the primary media (e.g., bitumen, asphalt, molten sulphur, tar, resins, polymers, adhesives, etc.).
    •    Outer Hose (Jacket): Circulates a heating or cooling medium (commonly steam, hot oil, or sometimes coolant) to maintain the required temperature of the product flowing inside the core hose.

 Key Features
    •    Temperature Control: Keeps viscous or solidifying materials at the right temperature during transfer.
    •    Construction:
    •    Inner Hose: Corrugated stainless steel or PTFE for chemical resistance.
    •    Outer Hose: Corrugated stainless steel with braid reinforcement.
    •    End Connections: Can be welded or flanged, with jacket inlets/outlets for steam/hot oil flow.
    •    Flexibility: More flexible than rigid jacketed pipes, suitable for installations where movement or vibration exists.
    •    Safety: Prevents clogging, solidification, or degradation of temperature-sensitive media.

 Applications
    •    Bitumen/asphalt transfer for road construction.
    •    Hot melt adhesives, waxes, and polymers.
    •    Sulphur and resins transport.
    •    Food processing (chocolate, syrups, oils that solidify at room temp).
    •    Chemical plants requiring constant heating/cooling of process fluids.

⸻

 Advantages
    •    Ensures continuous, clog-free flow of viscous media.
    •    Flexible design allows use in confined spaces where jacketed rigid piping isn’t possible.
    •    Can be custom-designed for specific pressure, temperature, and media compatibility.
