Hengyang Valin has contracted Danieli to supply two SDM cutting lines for its seamless pipe mill currently under construction in China, which is scheduled to be the world's largest.

The new cutting lines, one for billet cutting with 2 machines and one for tube layer cutting, will be integrated into the mill's FQM™ retained mandrel production line. This mill is designed to produce more than 800,000 tons of seamless pipes annually, with diameters ranging from 323.8 to 610 mm and wall thicknesses up to 65 mm.

Each line includes SDM vertical sawing units, cut-to-length systems, hydraulic stations, and automatic crop discharge. Danieli Automation will provide the control and process systems. Startup for the new lines is planned for 2026.
