现场管道施工，法兰材质为F22，阀门材质TP347，而八角垫材质是F5，请教各位这样选用合适吗？一般选用不是应该八角垫选用软一点的材质吗？

看管道内介质温度压力

F22 12Cr1MoV;F5 2Cr5Mo.请现场核实质保书。

tp 347 1Cr18Ni11Nb

再查设计的材料表，如的确如此，联系下设计。

谁说的八角垫选用软一点的材质？八角垫是线密封，应该是硬材质才对。

Reply #72019-11-26

八角垫硬的话则法兰密封易损坏，所以一般要求是八角垫的硬度低于法兰30HB左右

F22应该是2.5Cr0.5Mo（Cr2.5MO0.5吧，12CrMov 和F22没关系，F5相当于1Cr5Mo

建议联系设计沟通。提出自己意见。
