ERW (Electro-Resistance Welded) Pipe Line
As a result of rapid economic development in China, there is a high demand for good quality, large diameter ERW tubes for the oil & gas transportation, water & sewerage transportation and civil construction industries. To satisfy the requirements of our clients, we have our own patented HAOKUN ERW Tube production line. TO-date, we have supplied large diameter ERW16, ERW 20, ERW 24Ã¢â¬ to our various clients. We with to highlight a case where we have supplied a ERW 25 Tube Mill to Guangzhou Juyi Pipe Factory. In this Mill, we have also designed a Horizontal Loop Accumulator, a high speed Coil Edge Milling and a Flying Curter to enhance its capability. Another ERW 25 Tube Mill is also currently supplied by us to Mozambique WBHO Company. In addition to these references, we have gathered research data for ERW 630 X 19.1 mm steel grade X80 in our design library. We can confidently say that we have acquired state -of-the art know-how for large diameter ERW Tube Mill.
Following fast growth of Chinese economy, high-grade, large diameter 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 diameter 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: 16³ ERW, 20³ ERW, 24³ ERW. Among those the 20³ ERW, 24³ ERW production mills were already put into operation; For Guangzhou Juyi Steel Pipe Manufacturing Co., Ltd, another complete set of 25³ 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 25Ã¢â¬²ERW 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.
