围绕着近几年国内引进成型机建成的4套610和正在建设的3套660中直径高频焊管机组“在线定尺”成品长度为6.0~18.5 m的问题进行了讨论。研究分析了生产成品长度6.0~24.5 m焊管“在线定尺”、“精整线定尺”和“离线定尺”三个工艺方案,推荐“精整线定尺”工艺。建议对以船舶和铁路运输为主的中直径高频焊管企业,将焊管成品长度定为6.0~24.5 m,与国内目前普遍采用的成品长度6.0~18.5 m比较,不仅对海底输送管线用户有很强的竞争力,而且精整线综合小时生产能力将提高15.0%~35.0%,而投资仅增加4.178%;对以铁路运输为主的中直径高频焊管企业,建议采用“精整线定尺”工艺,将焊管成品长度定为6.0~12.25 m,与成品长度6.0~18.5 m比较,精整线小时生产能力将提高30%~35.0%,而投资仅增加3.280%。

On-line definite length for the finished products is 6.0~18.5 m in constructed 4 sets of φ610 forming machines and under constructing 3 sets of φ660 middle diameter high-frequency welded pipe units,this kind of definite length should be discussed.This article put forward on-line definite length, finishing line definite-length and off-line definite-length 3 kinds of procedures for finished welded pipe length 6.0~24.5 m,it recommend the second kind of procedure-finishing line definite length.It suggested middle diameter high-frequency welded pipe enterprises adopting the finished welded pipe length 6.0~24.5 m,such welded pipes will be mainly shipped through vessel and railway.Compared pipe length with finished product 6.0~18.5 m commonly used in China domestic,it is not only with strong competitiveness,but also with finishing line production capacity increase 15.0%~35.0% per hour,but investment only adding 4.178%;it suggest middle diameter high-frequency welded pipe enterprises adopt “finishing line definite-length” procedure,and set welded pipe length 6.0~12.25 m,comparing it with finished welded pipe length 6.0~18.5 m,its production capacity will enhance 30%~ 35.0%,but investment only adding 3.280%.
