DN600螺旋鋼管的焊接搭接

日期:2020-05-20

當我們檢查DN600螺旋鋼管的外觀時,經常會發現DN600螺旋鋼管的焊縫上會有接頭,那么為什么焊縫上會有接頭呢?當生產裝置停止并重新啟動時,將出現焊接搭接。然而,標準規定DN600螺旋鋼管焊縫允許搭接。

只要焊縫搭接接頭在探傷中合格,就不能作為拒收的理由。由于停車時DN600螺旋鋼管搭接處容易出現質量問題,DN600螺旋鋼管焊縫繼續焊接生產,探傷儀檢查DN600螺旋鋼管焊縫搭接處時,必須反復仔細地來回檢查,發現問題及時修復。一般來說,只要DN600螺旋鋼管焊縫的搭接接頭探傷合格,DN600螺旋鋼管制造商就不會再對搭接接頭進行修理和打磨。

然而,一些負責任的DN600螺旋鋼管制造商將要求生產人員修理和研磨DN600螺旋鋼管焊縫的搭接接頭,以確保搭接接頭和原始焊縫之間的平穩過渡。
