United Wagon Company and Ural Mining Metallurgical Company (UMMC) signed a number of contracts for the supply of tank cars which will be delivered to three UMMC subsidiaries. The contract envisages the supply of 73 tank cars for the transport of sulphuric acid by rail. By the end of January 20189, they will be delivered to Sredneuralsk Copper Smelter (SUMZ), Mednogorsk Copper and Sulfur Plant (MMSK) and Chelyabinsk Zinc Plant (CZP).
MMSK will receive 30 new generation 15-9545 model tank cars, 26 cars will be delivered to Chelyabinsk Zinc Plant and 17 cars to Sredneuralsk Copper Smelter.
The cars have an increased capacity of up to 77 tonnes, instead 62–69 tonnes and superior loading capacity, of 12%, compared with standard analogues. The improvements are thanks to strengthen of bogies and enlarged tank volume.
Technical features of the car include bent axis of the tank to enable full drainage of the product.
In the assembly of the tank-car tank support there has been applied the gasket made from high-molecular-weight polyethylene. This polyethylene is more resistant to aggressive media when compared to wood (counterpart tank cars have such wooden gaskets). Нatches are fitted with a fluoroplastic sealant, which is highly resistant to aggressive media, and are equipped with two nozzles: for loading of sulphuric acid and for gas removal. A flexible metal sleeve, hermetically attached to the second nozzle, is for removal of sulphur dioxide at depot degassing installations.
The tank car’s run distance before the first depot overhaul is up to 1 million km, or 8 years, against 210,000 km, or 2 years, for many cars currently in use. Service life of the Tikhvin’s tank cars is 18 years.
The new contracts are the second success in a row achieved by UWC in railcar tenders by UMMC during the last two years.
UWC has already delivered tank cars for sulphuric acid to two UMMC production subsidiaries, Sredneuralsk Copper Smelter and Svyatogor.
The new contracts will bring the total number of UWC cars in the UMMC fleet to over 100.
