GB6479化肥专用管全国最低价|厚壁无缝管理论重量表 化肥专用管：GB6479-2000（高压化肥设备用无缝钢管）。主要用于化肥设备上输送高温高压流体管道。代表材质为20、16Mn、12CrMo、12Cr2Mo等。０２２－８４８９２８８０
化肥专用管（GB6479-2000）是适用于工作温度为-40~400℃、工作压力为10~30Ma的化工设备和管道的优质碳素结构钢和合金钢无缝钢管。主要用来制造高压及其以上压力的蒸汽锅炉管道等用的优质碳素结构钢、合金结构钢和不锈耐热钢高压无缝管、这些锅炉管经高温和高压下工作、管子在高温烟气和水蒸汽的作用下还会发生氧化和腐蚀，因此要求化肥专用管有高的持久强度、高的抗氧化性能，并具有良好的组织稳定性。１３９２０３３１７６８付经理
化肥专用管使用温度在450℃以下，国产管主要用10号、20号碳结钢热轧管或冷拔管制造。
