Technological Progress and Product Mix Restructure of ERW Pipe Production

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.
