Special Tank Container
What makes a tank container a special tank container? In short we could say: A tank container that cannot be categorized by the other groups and therefore it is a wide variety of tank containers which we can divide in:
High Specification: Tank containers that are built to a higher T code than T14, in most cases T20 or T22. On request we can organize these tanks with an Asme U stamp approval which is needed for classified products of class 6.1. when operated in the USA. Class 6.1 products are toxic by inhalation which requires special attention to closures and gaskets. Such tank containers are built with a bolted manlid, preferably with a tongue and groove manlid seal, minimal with full flanged ball valves and a nitrogen connection since such products are loaded and discharged under a closed circuit with Nitrogen over pressure.
High Temperature: A standard tank is build to a design temperature of 130 degrees C. Products that require high temperature need special attention. This is related to the loading and discharge operation as well as the material of the tanks container, the design of the tanks container (the barrel will change dimensions due to the high temperature) and the required temperature during transport and te need to warm the product before discharge. Special attention should be given to the insulation of spill boxes and bottom cabinets as well as the possibility to heat the valves.
Modifcations needed for the operation: A product or process can require amendments on the tanks containers, nice examples are containers with legs for easy drop off form a chassis but also mixing device to keep a product moving duting storage.
Tank containers built for a dedicated product
Some products do have special requirements, this can be forged by the regulations but sometimes the market is demanding for higher specification tank containers than required.
An example of the first group are tank containers built for Hydrogen Peroxide, in most cases these are un-insulted tanks fitted with a breather valve as well as a 10” bursting disc.
An example for tank containers built to a higher spec are dedicated tank containers for Ethylene Oxide. The market is using a tank container that is built like a gas tank (T50) but certified as a liquid tank. The reason behind this is safety.
Tank containers fitted with an internal lining or a coating.
Although stainless steel is compatible with a large group of products there is also a need for products that are not compatible with stainless steel 316L. Often is the content chlorine the main problem, therefore it is important to have chemical knowledge and to study the msds sheet prior selecting a tank container. A commonly used protection is a lining or a coating.
A lining is protection that is applied in sheets, like PTFE or Rubber while a coating is applied with a spray gun. It sounds like and easy process but it requires full attention to details such as: no sharp edges, proper cleaning to avoid old loaded product in the stainless material, very clean work process, control over temperature during the application and curing of the coating, materials used on valves, preparation of flanges, type of manlid, gasket material, labeling of the tank container etc etc.
The successful operation of a lined tank container starts with the building/application process but also with a professional operation of the tanks container itself. A solid inspection program is required as well as control over the interior of the tank container where in most cases a nitrogen overpressure is needed.
