FFX成型技术在不锈钢焊管生产中的应用

Application of FFX Forming Technology in Stainless Steel Welded Pipe Production

在高频直缝焊管生产中,FFX成型技术作为一种先进的焊管成型工艺具有轧辊兼用程度高、成型稳定、自动化水平高等特点。介绍了FFX成型技术的原理,并与排辊成型技术进行了对比,分析了FFX成型技术的特点和优势。以S31803双相不锈钢为例,在Φ630 mm FFX成型机组上生产Φ219 mm不锈钢焊管,并对管材性能进行了分析。结果表明,采用FFX成型技术生产的不锈钢管产品性能稳定,减少了换辊时间,降低了生产成本。

In the production of the high-frequency longitudinal welded pipes,as an advanced welding pipe forming process,FFX forming technology has the characteristics of the high roller dual-use,stable forming,and high automation level.The principle of FFX forming technology is introduced and the roll forming technology is compared to it.The characteristics and advantages of FFX forming technology is analyzed.Taking the S31803 duplex stainless steel as an example,Φ219 mm stainless steel welded pipe is produced inΦ630 mm FFX forming unit,and the performance of the pipe was analyzed.The results showed that stainless steel pipe products are stable by using FFX forming technology,reduced roll changing time,and reduced production costs.
