Features of a Tank Container
Below, therefore, we have provided a summary of their main features, specification and components.
The data is from one of the market leaders for tank containers and courtesy of Stolt Nielsen.
Tank Container Components
|ISO Stolt Container
ISO compliant 20 foot tank container
|Top Airline Valve
The top airline valve allows for nitrogen purging, for pressurization during discharging, for vapor recovery and for pressure testing the tank.
|Bottom Outlet Assembly
Tanks may be discharged or loaded through the bottom outlet assembly, which features multiple valves to prevent leaks, even if the external assembly is accidentally ripped away.
Cladding is the outermost skin of the tank, covering the insulation and then the inner tank shell; cladding is usually made of glass reinforced plastic (GRP) or aluminum.
|Tank Data/CSC Plate
The data/CSC plate is a permanent feature that provides vital technical specifications of the tank, including periodic test dates.
|ISO Standardized Frame
The frame of a tank container is built to strict specifications provided by the International Organization for Standardization (ISO 6346) and other regulatory bodies.
The manlid covers the loading manhole at the top of the tank and permits entry to the tank for inspection, repair and/or cleaning purposes.
|PV Safety Release Valve
The PV (pressure/vacuum) safety release valve opens to either release excessive pressure inside the tank or to allow air to enter the tank in the case of excessive vacuum.
The temperature gauge constantly measures the temperature of the tank contents.
|Tank Container Walkway
The walkway provides a slip-resistant path for workers moving about on top of the tank.
Tank Container Specification
A typical tank container specification will look like those supplied by one of the UK’s top manufacturers and suppliers, UBH.
Stainless or carbon steel or carbon steel (other specialist materials e.g. titanium or hastelloy available on request).
Multi-compartment and baffled tank configurations.
Various internal finishes, up to 800 grit and electro-polished.
Vessel linings in PTFE, PFA, rubber, plastic, resin.
Temperature Control & Management
Specialised heating and cooling systems to match product requirements, available as liquid (glycol, water or oil), steam or electric blanket systems.
Rockwool, polyurethane or tanklite insulation.
Coloured GRP, pre-painted aluminium or stainless steel cladding.
Tank Containers In Container Home Designs
In standard shipping container home plans and architecture, tank containers are not generally considered part of the equation.
However, the intrinsic strength in tank container frames makes them ideal for larger shipping container homes where the storage of water, gas or other liquids might be necessary. By utilizing a tank container in this way, a container home construction is not reliant upon underground or other connecting infrastructure for energy storage or delivery.
Therefore, rural container home projects such as Cove Park, Scotland and Canada’s all-terrain cabins could benefit from such an application.
