Collaborative Confluence & Capacity Catalyst Amid Global Demand Surge

Since 2010, Jiuli’s tube-making operations have grown using SMS group’s mill technology and services. Now, the addition of a KPW 50 LC and two KPW 25 LC cold pilger mills at its Huzhou, Zhejiang plant signals a major escalation. Jiuli produces seamless stainless steel & special-alloy tubes for over 70 countries. This new capacity allows it to meet rising demand, especially in instrumentation, steam generators, petrochemicals, food processing, aerospace, and other critical industries relying on precise metallurgical standards.

Precision Pilgering & Process Prowess: Quality, Tolerances & Microstructure

Cold pilgering forces steel hollows through reducing rings while rotating, controlling tube wall thickness, diameter, and microstructure. Jiuli’s new pilger mills achieve exceptional dimensional accuracy, superior surface finish, and refined grain structure, essential for high-integrity tubes used in instrumentation and steam generator contexts. These enhancements reduce rework and enhance fatigue resistance, critical for demanding applications.

KPW 50 LC Capacities & Calibration Conquest for Mid‑Size Tubing

The KPW 50 LC transforms hollows 64 mm→25 mm into finished tubes 48 mm→14 mm using up to 1,000 kN rolling force at 200 strokes/min. This machine expands Jiuli’s capability in mid-bore tubing, such as pressure-relief lines, hydraulic systems, and process instrumentation. The precision automation ensures tight tolerances and uniform mechanical properties are delivered at scale, down to micrometer-level wall variance.

KPW 25 LC Compactness & Cycle‑Speed Supremacy for Fine Tubing

The twin KPW 25 LC mills specialize in smaller tubes, processing hollows 38 mm→12 mm into 30 mm→8 mm finished tubes with 440 kN force at 320 strokes/min. High-speed strokes and advanced feed control ensure uniform wall thickness, excellent ovality, and polished surface finish. These attributes are vital for instrumentation tubing, medical devices, and high-pressure steam generator tubes where failure is not an option.

Integrated Intelligence & Industry‑Grade Instrumentation Ecosystem

SMS delivers turnkey integration: electrical systems, automation, hydraulic circuits, tool kits, spare parts, and commissioning services. Installation and testing will be overseen by SMS engineers working closely with Jiuli staff. The axis of collaboration ensures smooth commissioning while minimizing production disruption. Remote diagnostics and service contracts under SMS’s Digital solutions promise ongoing performance optimisation and minimal downtime.

Strategic Spectrum & Sectoral Strengthening for Sustainable Growth

Jiuli uses these mills to deepen its market penetration, particularly in high-value sectors needing specialty alloys. Stainless and nickel-alloy tubes are critical for energy, aerospace, pharmaceutical, and food industries. The upgraded mill line enables Jiuli to enter new niches like semiconductor applications, cryogenics, and exotic alloy production, markets that require exacting tolerances, traceable material certifications, and reliable delivery timelines.

Future‑proof Fabrication & Flexible Foundations for Smart Manufacturing

The open-control architecture and digital automation in these mills support future Industry 4.0 integration. Jiuli gains readiness for digital twins, AI-enabled quality controls, predictive maintenance, and sustainability initiatives, like dynamic energy load balancing. This upgraded infrastructure positions Jiuli to adapt swiftly to changing demand, regulatory environments, and alloy innovations, cementing its competitiveness globally.
