ERW Mill-Pre-forming machine(Φ219mm-Φ630mm)
Following fast growth of Chinese economy, high-grade, large caliber and high frequency straight seam welded pipes are widely used in areas such as petroleum transportation, urban pipe line networks and constructions, pushing up demand for them which creates new development opportunities for pipe line manufacturing firms and equipment manufacturers.
During the recent years, by learning and developed large caliber ERW production lines(Φ219mm-Φ630mm)with our own intellectual property rights. Especially some single units, such as squeeze roller have been patented in China. So far, we have finished designing large caliber ERW production lines specifications: ERW16", ERW20", ERW24". Among those the ERW 20" mill, ERW24" mill were already put into operation: For Guangzhou Juyi Steel Pipe Manufacturing Co., Ltd, another complete set of ERW25" production line with horizontal accumulator. High Speed Edge Milling Machine with sawmill. Cutting Machine and Finishing Area, was already in operation: A complete set of ERW25" production line to be exported to WBHO in South Africa is already under testing.
In addition, our company has mastered all techniques for ERW 630mm × 19.1mm with iron grade X80, and has developed JCOE 1402mm× 32mm with iron grade X80 welded pipe production line.
