【Ferro-alloys.com】Severstal Russian Steel divisions Cherepovets Metallurgical Plant has reconstructed nine tanks for spent acid at the site of the metal pickling shop. The tanks of the solution warehouse of the hydrochloric acid regeneration unit URSK are designed for accumulation and supply of the regenerate to the continuous pickling units No 3 and No 4, as well as for receiving the spent pickling solution from them. The metal gummed containers were replaced with fiberglass containers with a special coating.

After assembly, new containers are treated with a special chemical resistant compound. Such storage is more reliable, since fiberglass does not react with an acidic solution, which guarantees safety and environmental friendliness of operation. We strive to support not only the main production facilities, but also ancillary equipment. The cost of this investment project amounted to 57 million rubles

The service life of fiberglass containers with a protective coating is 20 years. In 2022, it is planned to replace the remaining six tanks from the old park.
