Seamless tubes are at the core of numerous safety‑critical and high‑load applications. The requirements for dimensional accuracy, wall thickness, roundness and process stability in production are correspondingly high. The KOCKS 3‑roll Stretch Reducing Block (SRB®) is designed to meet these demands.
What sets high‑quality seamless tubes apart is the ability to consistently meet tight specifications on outside diameter, wall thickness, ovality and straightness, while delivering defined mechanical properties over the entire tube length.
These seamless tubes must ensure dimensional accuracy, material integrity and operational strength at the same time – over long service lives and often under extreme operating conditions.
In daily operations, seamless tube mills operate in a constant tension between the tightest specifications and economic production. On top of this comes the pressure to reduce material losses, optimize the use of mother tubes and at the same time meet very high market requirements.
This real‑world environment is exactly where the KOCKS SRB® proves its strengths. For decades, KOCKS has played a pioneering role in the development of stretch reducing blocks for the seamless tube industry. The SRB®, in use worldwide, embodies more than seven decades of continuous technology development. Many ideas and design details of the SRB® were created in close cooperation with tube producers and are now an integral part of modern hot tube mills.
In a modern seamless tube mill, the KOCKS SRB® occupies the position where dimensions, yield and economics are decided. As the central stretch reducing stage, it turns hollow shells into precise, saleable tubes – defining outside diameter, wall thickness and ovality in one compact 3‑roll block.
By stabilizing processes and protecting yield campaign after campaign, the SRB® becomes the core equipment around which a high‑performance seamless tube mill layout is built.
