company news about Reducing Material Waste in Continuous Strip Joining: Why India’s Leading Tube Plants are Adopting ZY80F’s Automated CO2 Welding

ZHANGJIAGANG, CHINA — As India’s industrial sector accelerates its infrastructure goals, efficiency in raw material utilization has become a defining factor for profitability. Zhangjiagang Zhongyue Metallurgy Equipment Technology Co., Ltd, a global leader in high-performance tube mill engineering, is transforming Indian manufacturing floors with its ZY80F Direct Forming Tube Mill. By integrating advanced automated strip joining technologies, this automated tube mill system is specifically designed to minimize material waste and maximize uptime for carbon steel pipe production lines.

Eliminating the Cost of Material Waste

In high-capacity tube plants, the transition between steel coils is often a primary source of scrap and operational delay. Traditional manual joining methods result in inconsistent weld seams that can damage downstream rollers or fail during the high-frequency welding process. Zhangjiagang Zhongyue Metallurgy Equipment Technology Co., Ltd addresses this with an integrated automated CO2 welding and hydraulic shearing system. This ensures that the head and tail of each steel strip, ranging from 150mm to 320mm in width, are perfectly aligned and joined with high-strength precision.

Data-Driven Performance for the Indian Market

For Indian manufacturers aiming for an annual capacity of 60,000 tons, every minute of downtime saved during coil changeover translates directly to the bottom line. The ZY80F system features a massive 6.5-meter diameter horizontal accumulator that supports a feeding speed of up to 150m/min, ensuring the production line never stops during the joining process.

The "Direct Forming" technology further enhances this efficiency by allowing the mill to process square tubes up to 80mm x 80mm and wall thicknesses up to 5.0mm without the traditional requirement of changing rolls. This seamless operation, powered by a total installed power of 800kw, allows for a consistent production speed of 80m/min, setting a new benchmark for high-speed square-to-square pipe machines in the region.

Precision and Reliability

Beyond material savings, the ZY80F ensures superior product quality through its single-blade cold cutting saw, which utilizes Yaskawa AC servo motors to achieve a cutting length tolerance of just ±2mm. This eliminates the need for secondary deburring, further reducing labor costs and material loss at the pipe ends.

As the preferred partner for India’s steel giants, Zhangjiagang Zhongyue Metallurgy Equipment Technology Co., Ltd continues to deliver turnkey solutions that combine Siemens-powered automation with heavy-duty durability. By choosing the ZY80F, Indian tube plants are not just buying a machine; they are investing in a future of sustainable, zero-waste manufacturing.
