The latest new facility commissioned by Hraninvest-HMC AD is an automatic manufacturing line for tanks in stainless steel AISI 304; AISI 316.

This machinery brings the company in the front ranks of the European manufactures of stainless steel tanks and the sole company on the Balkans for the wine, milk processing, brewing, chemical and other industries. Our engineers work together with world leading manufacturers from Italy for improvement of technologies for manufacture of such vessels, inclusive of pressurized vessels.

The line consists of machines for uncoiling, straightening, cutting, installation of thermal jackets, welding, grinding, cleaning of finished vessels and testing. This automatic line allows to manufacture tanks in large quantities and of volumes up to 150 cu.m. while ensuring a constant quality.
The manufacture of stainless tanks with thermal jacket for cooling or warming of liquids inside them is by employing a new technology. A cooling or heating source is used to create pressure up to 10 bar inside the point-welded sheets and form the jacket. The jackets are designed for a working pressure in the range of 5 – 6 bar (thermal jackets made by the old technology were designed for a maximum of 3 bar).

The completely automated welding process ensures quality and endurance of tanks and remarkably distinguishes their appearance as compared to the tanks made by the old technology.
The automatic line can also apply a protective film on the stainless steel sheets. The tanks manufactured at this line guarantee conformity and quality to European standards to our customers.
