Steel tanks

The first question that arises for consumers regarding steel tanks is their application and efficiency in the operation and process of food, pharmaceutical and petrochemical industry systems. Stainless steel have been used in the food industry for over a century. Due to its long shelflife, safety, non-pollution, hygiene and most importantly stainless properties, it is used for manufacturing of steel tanks. Steel tanks include various types, such as single, double and triple-walled tanks, which are also referred to as fermenters process tanks. Other examples of steel tanks including: milk storage tanks, single, double and triple wall silo tanks, glucose, fructose and acid tanks, mixer tanks, herbal essence and extract storage tanks, rose water storage tanks, dairy, cheese and syrup tanks, Cosmetic tanks, septic tanks and Isotanks.

Steel tank 316-Steel tank 304:

Steel tanks in grades 304 and 316 are the most widely used tanks in various industries due to their good metallurgical properties. The properties of the steels, including impact resistance, tensile and physical properties, resistance to high and low temperatures, etc., play an important role in the quality of construction of steel tanks. Excellent corrosion resistance properties of stainless steels against chemicals can be found in their percentage of chemical analysis in relation to the presence of alloying elements such as Cr = 18, Ni = 8, C = 3%, Mn = 2, Si = 0.75. The metallurgical function is such that when corrosive substances attack the wall of steel tanks, the element Cr = 18% enters into action and protects the surface, and because chromium is inherently self-healing in the environment, it plays an important role in the resistance of tanks. The metallurgical function is as follows: by corrosive attacks to the tank wall, Cr=18% protects the surface and Chromium plays an important role in resistance of tanks for its self-healing properties.

Purchase of steel tanks

There are some points to be noted in purchasing steel tanks. Most of the customers pay attention to the size, price and location of steel tanks at first sight. Although mentioned items are important but there are some other important features that needs to be considered as the priorities. By having following points in mind you could find the most optimal product with maximum efficiency and quality. The features are: the material used for the manufacturing of tanks, design and manufacturing process (WPS and NDT welding type), etc.

Damirchi Industrial Group offers a wide range of products by observing the whole manufacturing process and technical support of its materials and welding engineers to choose high quality raw materials and also mechanical and process engineers in terms of equipment.

Advantages of steel tanks


Corrosion protection: stainless steel is resistant to oxidation and bioxides due to Nickel and Chromium.


They have high resistance to cavities, grooves and abrasions associated with corrosive materials. Also high flexibility, heat resistance and welding capability are some other advantages.


Recyclability and hygiene: 70% recyclable and ineffective in food, Pharma and Hygienic materials, as well as after welding, polishing and acid washing operations, argon welds have given them priority in terms of hygiene. After welding, polishing and acid washing operations of argon welds have given them priority in terms of hygiene.


Easy transport and convenient appearance without the need for painting, insulation and lightness of steel tanks.


Cost savings for companies due to fewer repair services and durability of steel tanks. Given the above advantages, it is important to buy your tanks from a reputable and experienced company.

Steel tank construction steps

Another important point that should be considered in the manufacturing of steel tanks is the strength and resistance. In this regard, Damirchi Industrial Group has been able to manufacture in accordance with the latest world standards by using specialized software. Since a large part of steel tanks exist in the manufacturing process, it is necessary to consider the specific requirements in each section in design and construction. For example, in order to build a steel tank, used as cooking pots in the milk, beverage and juice industries, it is necessary to have special tanks while being equipped with the required heat and cold exchangers. In addition, the sampling inlet and outlet valves and the CIP section have standard and full insulation. Damirchi Industrial Group uses matched converters for steel tanks such as internal coils, heat exchangers (in the form of rotating or egg comb) and plate exchangers by manufacturing various types of converters. Also, for insulation of steel tanks, injected polyurethane with a specific weight of 40 kg / m3 can be used. Another important point for manufacturing a steel tank is the internal polish and proper installation of the drain and clean-in-place (CIP), which needs to be designed in a way that there will remain no trace of stored and washing materials after draining. Installation of additional equipment such as ladders and sensor mounting covers are also located in the tank based on the general principle. In general, it is necessary to avoid angulation inside the tanks and connect all the sections in a curved and circular manner.
