In a nutshell, the product is inserted through the filling port at the top of the barrel and usually discharged through the bottom outlet, either by gravity, pump or pressure. After discharge, the tank container is taken to a recognised cleaning station, cleaned thoroughly for the product it was previously carrying, and then made ready for its next load.
The manlid enables access to the tank interior for inspection and maintenance or cleaning. As the name suggests, the safety relief valve relieves excess pressure if necessary.
The top valve enables filling or discharge from the top. The air inlet is used to vent pressure or vacuum at the time of filling, discharge or cleaning. The spare flange is used for retrofitting an additional valve for specialist operations.
Measures the temperature of the tank contents.
Tanks are usually fitted with an integral steam heating system to enable heating should the substance solidify in transit or is otherwise below the temperature required by the receiver. The steam heating system comprises a series of channels welded to the underside of the tank shell to form pressure tight tubes.
The bottom valve enables the tank to be filled and discharged through the bottom opening.
To enable the tank to be operated from ground level, top valves might be remote-controlled. A cable mechanism will extend to the tank top.
Insulation guarantees a temperature-controlled environment, allowing the container to be heated or cooled. To provide for versatility of use, most general purpose tanks are insulated. Insulation additionally provides a degree of protection to the tank in the event of impact or fire engulfment.
Some tanks are fitted with a collapsible handrail for safety reasons when mounting the tank.
Contains detailed information including regulatory approval references.
The tank frame structurally supports the tank vessel and enables the tank to be lifted, transported and stacked. The rear-mounted ladder and top walkway provide the operator with access to the top service fittings.
