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 pipeline 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 absorbing advanced ERW machine technologies from abroad, we designed and developed large caliber ERW production lines 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 with specifications: 16 ' ERW, 20 ' ERW, 24 ' ERW. Among those the 20 ' ERW, 24 ' ERW production mill were already put into operation; For Guangzhou Juyi Steel Pipe Manufacturing Co., Ltd, another complete set of 25 ' ERW production line with horizontal loop, High Speed Edge Milling Machine with sawmill, Cutting Machine and Finishing Area, was already in operation; A complete set of 25 ' ERW line to be exported to WBHO in South Africa is already under testing.

In addition, our company has mastered all techniques for ERW630x19.1mm with iron grade X80, and has developed JCOE1420x32mm with iron grade X80 welded pipe production line.
