Our foundry professionals have manufactured the trial batch of cast-iron sector tubings designed to protect Moscow Subway tunnels from cave-ins.
This should be the start of the large RF Federal Government contract. These metal-consuming products will be manufactured per tight schedule. The total weigh of products manufactured per month is 400 tons.
Tubings are grey cast-iron sectors — a huge «Lego» from 500 to1500 kgin weight, coming in four sizes. They will be assembled on-site to become round-shaped framework (9,5 metersin diameter). Such rings will protect Moscow Subway tunnels against cave-ins.
