我們都知道T91合金管一般遇水或潮濕容易生銹，那么關于T91合金管如何來保存的

　　首先，我們應選擇一個適宜的場地或庫房來作為T91合金管的存放(fang)地點(dian)，應選擇在清潔(jie)干凈、排水通暢的地方，存放(fang)時不得與酸(suan)、堿、鹽、水泥等對T91合金管有侵蝕性的材料堆放(fang)在一起。

　　其次，在(zai)存放T91合(he)金管時我們要(yao)注意堆疊，在(zai)保證安(an)全的(de)情況下，注意垛底的(de)墊高、堅(jian)固和平整(zheng)這三個關鍵(jian)點，不同品種規格材質(zhi)的(de)分開(kai)存放，人工(gong)作業的(de)不超(chao)(chao)過(guo)(guo)1.2m，機械作業的(de)不超(chao)(chao)過(guo)(guo)1.5m，垛寬不超(chao)(chao)過(guo)(guo)2.5m。
