Abstract: A heatable container suitable for material such as bitumen. The container includes a vessel for holding a flowable material having side wall zones, end wall zones and a base wall zone. The container also includes a heating system for transferring heat to at least the base wall zone as well as a zone disposed along a central longitudinal axis of the vessel. The heating system may also included at least two internal heating ducts for conveying a heat transfer medium, wherein the ducts are disposed substantially parallel relative to the central longitudinal axis of the vessel, and are vertically and horizontally spaced apart relative to one another.

Abstract: THE INVENTION provides a novel heatable container suitable for material such as bitumen comprising a vessel, suitable for holding a flowable material, the vessel including side wall zones, end wall zones and a base wall zone;and heating means configured to transfer heat to at least the base wall zone as well as a zone disposed along a central longitudinal axis of the vessel; the heating means including at least two internal heating ducts, suitable for conveying a heat transfer medium, wherein the ducts are disposed substantially parallel relative to the central longitudinal axis of the vessel, and are vertically and horizontally spaced apart relative to one another.

Abstract: THE INVENTION provides a beatable container for bitumen, cut-back or the like, comprising a body member defining a base zone, side wall zones, end wall zone and a roof zone, characterized in means for transmitting heat from a heating medium to the base zone and to at least part of the side wall zones of the container.

Abstract: The installation comprises a rectangular, parallelepipedal, leaktight steam chamber (1) provided with a gate (2) on one of the short sides, inside which a tubular fixed mold (4) of perforated steel plate is attached at a distance from the walls of the chamber, the shape of the mold corresponding to the external shape of the panel to be obtained. A first set of fixed, parallel, perforated metal tubes (5), inside the mold (4), possesses lateral holes (9) for the passage of a second set of perforated or non-perforated metal tubes (10) firmly fixed to a movable external support (11), passing through one of the short walls of the steam chamber (1) and capable of moving perpendicular to the tubes (5) of the first set, passing through the latter. The chamber (1) is provided with inlet valves (13) for the partially expanded synthetic material, an inlet (14) for steam and an inlet (15) for a cooling fluid.
