Zhejiang Jiuli Hi-Tech Metals Co., Ltd., a leading Chinese manufacturer of stainless steel and special alloy products, has ordered three cold pilger mills from SMS group, one KPW 50 LC and two KPW 25 LC, for its facility in Huzhou City, Zhejiang Province. The investment supports Jiuli’s global expansion strategy to increase production of high-quality seamless tubes for demanding sectors such as instrumentation and steam generation.
The new mills will enhance Jiuli’s production capabilities by providing precise control over tube dimensions and wall thickness, improving mechanical properties and overall product quality. Jiuli already operates several cold pilger mills from SMS and supplies high-performance tubes to over 70 countries.
The KPW 50 LC mill can process hollows from 64 mm down to 25 mm, reducing them to final diameters of 48 mm to 14 mm using a 1,000 kN rolling force at 200 strokes per minute. The two KPW 25 LC mills handle smaller diameters, converting hollows from 38 mm to 12 mm into final sizes of 30 mm to 8 mm. They operate at 320 strokes per minute with a maximum rolling force of 440 kN, delivering uniform wall thickness and excellent surface quality.
SMS’s scope of supply includes the complete mechanical setup, integrated electrical and automation systems, fluid systems, tooling, spare parts, and technical support for installation, commissioning, and testing, ensuring a smooth integration into Jiuli’s operations.
