A transportation trailer can include a cargo tank with a shell that includes an outer wall, an inner wall, and an insulating core between the outer wall and the inner wall. The shell can be unsupported by structural rings, and the cargo tank can be a frameless cargo tank. The cargo tank can be formed by decoiling respective coils of inner-wall material, outer-wall material, and insulating-core material, joining the inner-wall material, the insulating-core material, and the outer-wall material to form a sandwich-type panel, and welding the sandwich-type panel to form the shell.

A superheater truck comprises a shell, a heat source, a heat exchanger, at least two flame arrestors, a plurality of parallel rows of fins, and a plurality of corrugated fins disposed between the parallel rows of fins. The heat source is within the shell and comprises at least one inlet vent and at least one outlet vent. The heat exchanger is within the shell and is configured to exchange heat received from the heat source and a fluid within the heat exchanger. A first one of the at least two flame arrestors is at the inlet vent, and a second one of the at least two flame arrestors is at the outlet vent.

A cargo transport heating system is utilized for a truck that includes a cargo containment and a combustion engine having a coolant inlet and a coolant outlet. The cargo transport heating system includes a heat exchanger, a coolant pump, and a combustion engine coolant having a low toxicity. The heat exchanger is disposed in the cargo containment, and is in fluid communication with the first coolant inlet. The coolant pump is in fluid communication with the coolant outlet and the heat exchanger, and pumps the combustion engine coolant through the first coolant inlet, the coolant outlet, and the heat exchanger.

A method of transporting waxy crude hydrocarbon includes: providing a container having an internal chamber with at least one port for receiving flowable waxy crude, wherein the container is provided at a refinery location; filling the internal chamber of the container with a filling system for loading the waxy crude hydrocarbon into the container; allowing the waxy crude hydrocarbon to cool and solidify into a non-flowable state; transporting the container having the non-flowable waxy crude hydrocarbon with at least one transport vehicle, wherein the transporting is performed without actively heating the waxy crude hydrocarbon with an active heating system, wherein the transporting is along a transportation route having a beginning at the refinery location and an ending; heating the waxy crude hydrocarbon at the ending of the transportation route until flowable; and removing the flowable waxy crude hydrocarbon from the container with an emptying system.

A tailgate assembly for a roll-off container includes a tailgate hinge that is operable to attach a tailgate to a container such that the tailgate is movable between an open position and a closed position. A sealing material located between the container and the tailgate when the tailgate is in the closed position.

A tailgate assembly includes a tailgate hinge that is operable to attach a tailgate to a vacuum tank such that the tailgate is movable between an open position and a closed position, the vacuum tank operable to withstand vacuum pressure when the tailgate is in the closed position. A tailgate warming tube loop is operable to circulate a heated fluid through the tailgate, the tailgate warming tube loop attached to an interior surface of the tailgate and a first rear pipe flange that includes a first rear pipe flange warming channel in communication with the tailgate warming tube loop.

A heated slurry transport system for receiving, transporting and unloading a cuttings slurry in a non-frozen manner in cold weather environments. The heated slurry transport system generally includes a portable tank having an interior surface, at least one wall, and a rear door. A layer of insulation surrounds at least a portion of the portable tank to help retain heat within the portable tank. A heating unit is attached to the portable tank and adapted to heat a fluid that is transferred through at least one heat loop attached to the portable tank to heat the interior of the portable tank and the contents of the portable tank.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A low-temperature container, low-temperature tank and low-temperature tank truck are provided. The low-temperature container includes a housing and an inner container disposed inside the housing through a support assembly. The support assembly includes two transverse support structures correspondingly disposed between the housing body and inner container body, and two longitudinal support structures respectively disposed between the outer sealing head and the inner sealing head located at ends. An central lines of the two longitudinal support structures and an central axis of the inner container are collinear, or the central lines of the two longitudinal support structures are parallel to the central axis of the inner container, and the longitudinal support structures may extend and retract in the longitudinal direction of the low-temperature container. The low-temperature container of the present disclosure has balanced support points and good heat insulation effect.

The disclosure generally pertains to systems and methods for heating a fluid being transported in a vehicle. An example method includes identifying, by a processor, a target fluid temperature and determining, based on the target fluid temperature, a separation distance between a tank attached to an underbody of the vehicle and an inductive heating element embedded in a road. The processor lowers the tank to a heating position above the inductive heating element based on the separation distance, and retains the tank in the heating position for using the inductive heating element to heat a fluid contained in the tank. The processor may raise the tank to a retracted position upon determining that the fluid has been heated to the target fluid temperature. The processor re-lowers the tank to the heating position upon detecting a drop in temperature of the fluid when the tank is in the retracted position.
