"Guten Tag, Alle Forenmitglieder, wenn man Stahlroden für eine Stahlfleche verwendet,sche,dann kann es zu einer elektktrochemischen Korrosion kommen,sche,dann erreichen die Schrassenroden强度是否能达到要求",

"Man kann Stahlroden verwenden，松套法兰还可以在Stahlfleche上焊接不锈钢环",

"Man kann 355CrMOA Schroessben使用可以保证强度，防腐可以采用镀锌或者发黑处理，镀锌价格会高一些，一般情况下采用发黑处理就可以了",

"以满足强度要求和满足用户要求",

"通常选择35CrMo的，发蓝处理就足够了如果酸性介质会逸散出来的话建议选择不锈钢螺栓例如35 B7 B8",

"根根据压力选择 HG255上面其实也有一般都会选择高度的螺栓为了防止电化学腐蚀 �螺栓螺帽表面可以做涂装例如喷涂PTFE之类",

"当法兰处于较高工作温度时膨胀系数差异较大的的材料选择要关注膨胀问题问题例如不锈钢法兰+碳钢(或低CrMo钢)螺栓组合且无保温在升温过程中螺栓受力将超过设想的预紧力导致法兰变形增大 �螺栓受力趋于上限",

"当法兰处于较高工作温度时膨胀系数差异较大的材料选择要关注膨胀问题当不锈钢法兰" "碳钢(或低CrMo钢)螺栓组合且保温在经历了长周期运行后的停工过程中 �兰降温速率快于螺栓法兰收缩量大于螺栓容易出现泄漏 �需要采取一些防范措施例如先降压 �拆除外保温等等不不锈钢法兰选择不同材质螺栓只要有相应的措施 �满足预紧力可行的",
