  在进行氧气站工程施工中,其空分塔内管道有相当多的工程均为铝镁合金 管道。在氧气站施工过程中,q355b合金钢管的施工方法与常见的碳钢管道、不 锈钢管道的施工方法有很大的区别,铝镁合金属于软质金属,铝镁合金具有良 好的耐腐蚀性和较高的低温强度,所以被广泛应用于制氧设备和化工工程中。 铝镁合金与黑色金属相比具有特殊的物理和化学性能。铝镁合金管线安装时具 有管径大、壁厚厚,现场制作件多,焊接连续作业时间长,焊接技术不易掌握, 坡口加工费时、费力,组对难度大,内部清洁度要求高,质量不易保证等难点。 目前q355b合金钢管在与预制口、固定口和管道间的对口焊接时,基本依据操作 人员的施工经验和一些木锤、橡胶锤等简易工具来进行管道的对口作业,但其 往往不能快速有效地进行管道对口,费工费时,且不能保证管道管口的焊接质量。
