Abstract: In domestic weld-pipe industrial circles,there exists a debate concerning a proper choice for the ERW pipe mill to be made between the single-forming process and the continuous forming process.Analysis and comparison respecting to these two processes are made in terms of product lines,technological advancement,annual capacity,yield,product quality,energy consumption and investment scale,etc.As a result,it is concluded that the single-forming process will enable the ERW mill to be more technologically superior than it would be in case of the continuous forming process,and accordingly it is proposed for future ERW mill line builders to adopt the single-forming process as the most possibly alternative.
