In the world of foundry engineering, precision, durability, and safety are critical, especially when it comes to infrastructure applications like mining, tunnelling, and civil engineering. One of the most essential yet specialised components in these industries is the tubbing ring: a cast product that forms part of the structural lining for vertical shafts and tunnels.
At Woosung Tubbing, a division of The Woosung Metal Company, we specialise in producing high-performance tubbing solutions through decades of experience in advanced casting and foundry engineering.
But what exactly is tubbing, and why does it matter in modern infrastructure?
Tubbing refers to the process of manufacturing cast iron or steel rings used to line the walls of vertical shafts, particularly in mining and underground construction. These interlocking segments provide long-lasting protection against ground pressure and water ingress, reinforcing the shaft walls and ensuring safe working conditions.
In foundry engineering, producing tubbing rings requires high levels of precision, robust material selection, and consistency in form. Unlike standard cast products, tubbing rings are engineered to exact tolerances to create a tight seal, especially in deep or unstable environments.
At Woosung Tubbing, our expertise in complex geometries and machine-moulding allows us to manufacture tubbing solutions that meet demanding structural and environmental requirements.
Tubbing plays a critical role in industries where structural reliability underground is non-negotiable. You’ll find Woosung Tubbing products in use across:
By supplying engineered tubbing rings to some of the world’s most challenging infrastructure projects, we help our clients achieve performance and longevity in environments where failure isn’t an option.
What sets Woosung Tubbing apart is our end-to-end production capability. From prototype development to large-scale manufacturing, we handle every stage in-house, offering full process visibility, faster turnaround times, and tighter quality control.
Every product is backed by certified quality standards, ensuring our tubbing rings deliver on strength, precision, and durability.
Our focus on innovation in metallurgy also allows us to produce cast iron with superior workability and consistency. This ensures each tubbing ring not only meets specifications but also performs reliably under the most demanding conditions.
