CII中弹簧的设置？ extended range，（是否使用扩展的载荷范围）。cold load，（冷态吊零） hot load centered（热态载荷居中） ... 首先谢谢您的解释。还有个疑问，关于冷态吊零， cold load spring hanger design is a method of designing the springs in which the hot (or operating) load is supported in the cold (or installed) position of the piping.这句话该怎么理解？(冷态时承受的载荷是热态时管系分配的力?),还有就是，如果三个都不勾选，那么是否默认应用热态吊零的方法选择弹簧? 期待您的指点，谢谢！查看更多
请教红色部分怎么翻译？ the flux cored arc welding (fcaw) process shall utilize an external shielding gas and is not permitted for the root pass of joints made from one side. fcaw may be used for the root pass of joints made from both sides only if it is completely removed prior to welding from the reverse side. flux cored arc welding (fcaw) 药芯 焊丝电弧焊 (fcaw) root pass 根部焊道 external shielding gas 外加保护气体 药芯焊丝电弧焊（fcaw）应使用（外部）保护气体但不得用于根部焊道的单面焊。药芯焊丝电弧焊可用于根部焊道双面焊，但根部焊道在反面焊接前应完全去除。 查看更多
