Metinvest Group’s KAMETSTAL plant, which was set up at the facilities of Dnipro Metallurgical Plant (DMK, Kamenskoye, Dnipro Oblast), is overhauling two pipelines to improve the reliability of compressed air and autogenous oxygen supplies.
According to the company, the Oxygen Compressor Shop (OCS) is carrying out the first stage of scattered overhauls on two pipelines at once. This integrated approach will help improve the reliability of compressed air and autogenous oxygen supplies for sinter production.
The company explains that due to significant wear and tear, both pipelines need to be upgraded as a matter of priority to avoid disruptions in the transportation of the products produced by the Coke Plant, which are essential for a stable technological process in the sinter and blast furnace shops.
As part of the overhaul of the autogenous oxygen network, it is planned to replace 700 meters of 108 mm diameter pipeline, upgrade valves and maintenance platforms, and repair stairs to improve safety and working conditions for personnel.
More than 300 meters of 530 mm diameter pipeline is also planned to be replaced in the external compressed air network. Ladders and platforms will be brought in line with the company’s standards.
“These are the first overhauls on both pipelines since their commissioning. The main task we are solving with these repairs is to ensure reliable supply of products manufactured in our shop and required for stable technical processes in sintering and blast furnace production. Also, after the network upgrade, we expect to reduce losses during the transportation of compressed air and autogenous oxygen,” explained Andrey Pismenny, Head of the PSC.
“KAMETSTAL was established on the basis of Dnipro Coke and Chemical Plant (DKKhZ) and Centralized Steel Works of Dnipro Metallurgical Plant (DMK).
According to the 2020 report of Metinvest Group’s parent company, Metinvest B.V. (Netherlands) owned 100% of the shares in DCCP.
