金属膨胀节加固：什么时候做、怎么做、做到什么程度？
一、膨胀节为什么要加固？——压力推力才是隐形杀手前两天接到一个客户的电话，说他们厂里一条蒸汽管道上的金属膨胀节用了不到两年，波纹管就鼓包了，现场一看，好家伙——膨胀节直接被压力推力顶成了“孕妇肚”。很多人以为膨胀节就是个软连接，只要管子不漏...
金属膨胀节缺陷从设计到安装：最常见的坑和解决思路
一张失效照片引发的思考——金属膨胀节到底能出什么幺蛾子？前两天整理现场案例，翻到一张图：波纹管像被刀切过一样，裂纹从波谷直延伸到波峰，焊缝处还挂着冷凝水滴。旁边标牌写着“刚投运三个月”。说实话，这场景见多了，但每次看到还是心疼——不光是设备...
蒸汽管道用金属膨胀节怎么选？这几点搞错会出大问题
蒸汽管道的工况有多“变态”？先聊聊蒸汽管道的真实环境——高温、高压、水击、腐蚀，四个“狠角色”轮番上阵。中压蒸汽动辄350℃，高压蒸汽直奔500℃以上。波纹管材料选不对？304只能打底，316L是起步价，真要碰上超临界蒸汽，得上Incone...
