ERW焊管的技术进步与产品结构调整

Technological Progress and Product Mix Restructure of ERW Pipe Production

综合分析了国内外尤其是国外工业发达国家ERW焊管的发展状况、技术进步及产品结构的调整方向,指出焊管产品应趋于个性化和高性能化,制管工艺技术应向专业化、差异化和节约化的方向发展。当前ERW焊管技术在对成型和焊接技术进行完善的同时,正在向原材料制造控制、钢管的深加工及节能降耗等方面延伸和扩展,这将是国内ERW焊管结构调整的方向。

Analyzed here in the paper are the development situations, technological progresses and the trend of product mix restructure of ERW pipe production both at home and abroad, focusing on these aspects of some major industrialized countries. Based on the analysis, it is concluded that the application of ERW pipes should be more and more individualized and highly-effective, and related pipe manufacturing technologies should be developed in an orientation of specialization, differentiality and saving-effectiveness. In addition it is pointed out that at present the ERW pipe-making technology is not only being improved in formation process and welding process, but also extended and expanded into related areas such as control of production of materials, deep-processing of ERW pipes and energy-saving/consumption-reduction, etc. These development trends are expected to be followed when domestic ERW pipe-making circles are performing product mix restructure.
