What is a tank container?
The tank container was developed to carry all types of liquids, ranging from, but not limited to, food grade liquids, non hazardous and hazardous liquids, corrosives, flammables, toxics and explosives. They provide a safe, secure and cost effective mode of transport. Generally tank containers are 20ft long and 8ft 6 inches high and the standard width is 8ft.

What is a tank container made from?
A tank container normally consists of a single cylindrical vessel within a rectangular steel framework. The frame is built according to ISO specification. The tank body is usually built from stainless steel or carbon steel and has one or more loading openings at the top (commonly known as manholes) and one central discharge point at the bottom.

What is the Specific Gravity (SG) and why does it matter?
The specific gravity or SG of a product is the weight or density of a solid or liquid expressed by the ratio of its weight to that of an equal volume of a substance taken as a standard (usually water in the case of liquids). The SG helps determine what size tank will be suitable for your needs, the higher the SG (the more the product weighs) the smaller the tank will be. Please use our free online SG calculator here.

What is a standard tank and what things make it special?
A standard tank will usually contain the following:
1. 4 bar working pressure and a 6 bar test pressure
2. Minimum shell thickness of 6mm with mild steel or equivalent in stainless steel
3. A single bottom discharge valve with a 3” BSP
4. Steam heating tubes
5. A single top pressure valve also knows as a PV
6. Tare weight between 3,500-4100kg
7. Insulation of 50mm
8. Tank sizes ranging from 14,000 to 29,000 liters

Where are your approved depots?
Tank Containers has a national network of approved depots in all the major cities, our dedicated repairs and maintenance team has implemented repair standards with most of the major depots. For more information please contact a Tank Containers representative.

What type of features can I get on a tank container?
On the top of the tank container you can find a walkway or collapsible safety handrails. To climb on top of the tank, a ladder is also installed at the back. Most tanks will also contain a document tube that is sufficient size to contain all the necessary load documentation. Generally tanks also come with a pressure/vacuum relief valve, airline connection, data plate, steam heating and bottom foot valve closure.

What are the different loading and discharge methods for a tank container?
There are many different ways you can load a tank, the most common is gravity loading through the manhole. The cargo flows freely from an overhead storage tank or pumped through a hose into the tank container. Other loading methods may include a closed system gravity or pressure loading through the top of bottom outlets.

The most common discharge methods include gravity discharge where the cargo flows freely through the bottom outlet to another storage tank. You can also use pressure discharge where the cargo is discharged through the top of bottom outlets by putting pressure in the tank container. Another method is to use suction from a suitable pump. Air or gas must be allowed into the tank container to replace the cargo being discharged, this is known as the pumped discharge method. Please speak to our representatives if you need more information.

When I return the tank do I have to pay for the damage?
All tank containers are surveyed for damage before they leave our depots. We take detailed photos inside and outside of the tanks and do a complete on-hire condition report. This can be sent to the client if they require a copy. Cleaning certificates are also issued before each tank is released. The client will be required to pay for any damage or cleaning to the tank that is not general wear and tear, please contact a Tank Containers representative for more information.

What is Ullage and why does it matter?
The Ullage is the unfilled space in a tank container after it has been loaded with cargo. The fill ranges between a minimum of 80% and a maximum of 98%. Filling ratios must never be less than 80% for tanks not partitioned into compartments of less than 7,500 liters. If you do not fill the tank properly it can cause the centre of gravity to shift from side to side or surge fore or aft. When the tank is correctly filled this should not affect stability.

Are your tanks tested periodically?
Every tank is periodically tested; these are performed every 2.5 years. The depots ensure the tank is repaired and made ready for test, after which a competent authority (BV, DNV etc) will certify the container. The 2.5-year test usually involves filling the tank with air and checking to see if it is completely airtight. All valves and seals are also checked. The 5-year test is more detailed and involves filling the tank with water and checking for any leaks; all valves and seals are also checked.
