Composite mandrel
The mandrel is a key rolling tool in the seamless steel pipe production process, significantly influencing both product quality and rolling costs. In hot‑rolling lines, mandrel consumption accounts for more than 50% of the total tooling expenses across the entire production line. Our company’s newly developed composite mandrel can substantially reduce rolling costs and shorten the procurement lead time for seamless steel pipes—without compromising product quality. Users can flexibly select the appropriate mandrel model based on the mill type and specific production conditions.

Product Details
The mandrel is a key rolling tool in the seamless steel pipe rolling process, significantly influencing product quality and rolling costs. In hot‑rolling lines, mandrel consumption accounts for more than 50% of the total tooling expenses across the entire production line. The composite mandrel developed by our company can substantially reduce rolling costs and shorten the procurement lead time for seamless steel pipes, all without compromising product quality. Users can flexibly select the appropriate mandrel model based on the mill type and actual production conditions.
Core shaft size
Diameter: 80–530 mm / 1.97–20.08 inches
Maximum length: 25,000 mm / 985 in
The composite mandrel is manufactured using our proprietary composite material and a build-up welding process. Leveraging advanced technology and state-of-the-art equipment, we can produce and remanufacture steel products that outperform competing offerings. The specialized materials employed enable the product to operate under extremely high‑temperature conditions, effectively reducing thermal fatigue and significantly enhancing red hardness. Our innovative composite build-up welding and coating technologies not only broaden the mandrel’s range of applications but also markedly extend its service life. Most notably, these advancements allow a single mandrel to be reused an unlimited number of times, thereby substantially lowering the rolling costs of seamless steel tubes.
Advantages:
1. Low manufacturing costs;
2. Its service life is comparable to that of conventional H13 mandrels;
3. Reusable;
4. Significantly reduce rolling costs without compromising product quality.
