style="text-indent:25px">銅管配管中難免有過長或者拼接情況，銅管過長需割斷，為了保證斷面平整方便拼接焊接或者擴口等操作，必須使用割管刀，避免使用除割管刀以外的任何工具進行對銅管的切割工作，否則的話使用其他工具導(dǎo)致的不平整斷面會影響以后的焊接、擴口等操作質(zhì)量，直接影響到系統(tǒng)氣密性。操作方法：針對所需要割斷的銅管選擇大小合適的割管刀，卡緊銅管，但不要過緊導(dǎo)致銅管變形以及切割困難。割管刀每旋轉(zhuǎn)一周，手柄也要跟進旋轉(zhuǎn)卡緊銅管，直至自然割斷，不可用手直接掰斷。割斷之后需進行去內(nèi)部毛刺。因為銅管可以彎曲、變形，它常?？梢宰龀蓮濐^和接頭，光滑的彎曲允許銅管以任何角度折彎。杭州艾默生制冷配件工廠</p><p
