螺旋鋼管橢圓如何修復?

日期:2020-02-15

螺旋鋼管的橢圓度標準是,最大外徑不得大于標稱外徑的1%,最小外徑不得小于標稱外徑的1%。在將施工現場焊接在口上時,不對接螺旋鋼管的端口的橢圓形時,最有可能出現橢圓形的螺旋鋼管?

螺旋鋼管橢圓如何修復?

當螺旋鋼管的焊接端由于焊接缺陷而修復時,橢圓形易于出現,并且頭部接頭板的螺旋鋼管易于呈現橢圓形。當遇到管端維修或管體與頭部接頭板的大量維修焊接時,必須仔細測量螺旋鋼管的橢圓度。如果出現超標現象,有必要進行維修。螺旋鋼管的橢圓形缺陷通常使用千斤頂修復。測量最小直徑。用千斤頂頂到最小的地方。這需要一個小時到五個小時。卸下千斤頂后,測量橢圓度。對于無法修復的橢圓,應及時報告質量檢查,以檢查螺旋鋼管是否退化或報廢。
