IRON CAST TUBINGS
Tubing rings for constructing underground railways mines
Iron cast tubings are elements, made in a shape of a ring segment and they are parts of a precast structure (mine-rings), which is used for forming and fixing inside face of underground constructions, underground railways and mines. Mine rings are gathered together in a tubbing. Each of these rings is made of a main segment and a couple of adjacent segments and also some unusual ones. Each of these separate segments of a tunnel ring (tubing) has its own geometry.
Tubings are widely used in special branches of industry. Without them it would be practically impossible to construct reliable and safe trunks of mines, vertical, horizontal and inclined tunnels, ore chutes and underground railways.
