Storing loose substances and liquids often entails the necessity to choose the right container – completely safe and ensuring protection of the stored materials. The three most important types of tanks are the following: aluminum, carbon steel and acid-resistant.
It is crucial to choose the container with a view of its future purpose. It allows to safely store all substances, without the risk of losing tightness or side effects caused by inappropriate choice of such containers.
Aluminum containers are most often used for storing liquid nitrogen. They usually have a large diameter of the hole, which facilitates access to the liquid. The containers are most often equipped with, among other things, low-pressure nitrogen pump system, which allows its safe retrieval.
Carbon steel containers are perfect for storing loose substances and liquids. However, it is important to remember that they may be mainly used for storing non-aggressive liquids, such as water or glycol. The containers have welded structure and cylindrical coat, which ends with two ellipsoidal bottoms, a hatch allowing control and maintenance of the inside surface as well as spigots for input and output of liquids. What is more – some models are protected against corrosion by way of galvanization or anti-corrosive paint.
In case of storing hazardous substances, i.a. aggressive acids, it is worth using acid-resistant containers. Such structures include basic equipment, such as dosing pumps, shut-off valves and regulating valves, liquid sight glasses or leak detection probes. Such structures often have double walls, thanks to which they are more mechanically durable and protected against loss of tightness.
