Hengyang Valin expands seamless pipe project with Danieli cutting lines

Hengyang Valin has awarded Danieli the supply of two SDM cutting lines to be integrated into the world’s largest seamless pipe mill, currently under construction in China.

The new lines—one for billet cutting with 2 machines and one for tube layer cutting —will be connected to the FQM™ retained mandrel mill production line, designed for annual production of over 800,000 tons of seamless pipes from 323.8 to 610 mm in diameter and wall thicknesses up to 65 mm.

Each cutting line will feature SDM vertical sawing units, cut-to-length systems, hydraulic stations, and automatic crop discharge. Automation and process control will be provided by Danieli Automation.

Startup is scheduled for 2026.
