When it comes to transport or store liquid products like alcohol, milk, oil, or any other chemical products, the common dry cargo containers cannot be used. In this case, we might have to use the tank containers to ship or store.
Usually, Tank containers are special containers that are manufactured for the transport of liquid goods such as foods, pharmaceuticals, and chemical products. When loading, the goods enter from the top loading hole of the tank, when unloading, the goods flow out of the discharge hole or sucked out from the top loading hole. Tank containers are generally used for shipping liquid or gaseous bulk cargoes, and can also be used to ship dry bulk cargo if conditions are suitable.
The tank containers are made of carbon steel or stainless steel. In general, it is a pressure vessel that withstands internal pressure, but it does not exclude negative pressure vessels. The minimum test pressure varies from different cargo types. The minimum test pressure is generally in the range of 45 kPa to 2200 kPa. Therefore, the tank container can ship dangerous goods within a certain range.
The tank container is mainly composed of liquid tank and frame. Liquid tanks are oval or nearly spherical and have a double-layer structure. The inner wall is made of stainless steel or other rigid materials, but a layer of epoxy resin is required to prevent the corrosion of liquid cargo. The outer wall is insulated. There is a loading port on top of the tank and a valve for unloading from the bottom of the tank.
There are several kinds of liquid tanks, like high-pressure liquid tanks, low-pressure liquid tanks, insulation tanks, tanks with heating devices, etc. The frame is made of high-strength steel and the tank is placed in the middle of the frame. The handling, loading, unloading, and storage of tank containers require certain specialized sites and special fire safety equipment.
The outer frame size of the tank container is exactly the same as the size of the International Standard 20 container (20 feet long, 8 feet wide, 8 feet 6 inches high). The tank containers can be used for road, rail and river/sea transportation, Loading up to 14300 to 31000 liters (or more ) of fluid cargo.
There are eight types of tank containers according to ISO and IMDG. Tullyn Trading can supply all the eight type, IMO0, IMO1, IMO2, IMO4, IMO5, IMO6, IMO7, IMO8. In addition to having all the advantages of containerized transportation, compared with the transport method in which ” a number of drums are loaded into a dry cargo standard container “, It is economical, fast, safe, environmentally friendly, beautiful and many other advantages.
