保管方(fang)法(fa)1．選(xuan)擇適宜的場地和庫房

(1)保管鋼管的場(chang)地或倉庫，應選擇(ze)在清潔干凈、排水通暢的地方，遠離產生有害氣體或粉(fen)塵(chen)的廠礦。在場(chang)地上(shang)要(yao)清除雜(za)草(cao)及一切(qie)雜(za)物，

(2)在倉庫(ku)里不(bu)得與酸、堿、鹽、水泥等(deng)對鋼管有侵蝕性的材料(liao)堆放(fang)在一起。不(bu)同品種的鋼管應(ying)分別堆放(fang)，防止混淆(xiao)，

(3)大型型鋼(gang)、鋼(gang)軌、辱鋼(gang)板、大口(kou)徑鋼(gang)管、鍛件等(deng)可(ke)以露天堆放(fang)；

(4)中小(xiao)型型鋼(gang)(gang)、盤條、鋼(gang)(gang)筋、中口徑鋼(gang)(gang)管、鋼(gang)(gang)絲(si)及鋼(gang)(gang)絲(si)繩等，可(ke)在通(tong)風(feng)良好的料棚內存(cun)放，

(5)一些(xie)小型鋼(gang)(gang)管(guan)(guan)(guan)、薄鋼(gang)(gang)板、鋼(gang)(gang)帶、硅鋼(gang)(gang)片、小口(kou)徑或薄壁鋼(gang)(gang)管(guan)(guan)(guan)、各種冷軋、冷拔(ba)鋼(gang)(gang)管(guan)(guan)(guan)以及價格高、易腐蝕(shi)的金屬制品(pin)，

(6)庫(ku)房(fang)應根(gen)據(ju)地理條件選定(ding)，一般采用普通(tong)封閉式庫(ku)房(fang)，即有房(fang)頂有圍墻(qiang)、門(men)窗嚴密，

(7)庫房要求晴天(tian)注(zhu)意通風，雨天(tian)注(zhu)意關閉防潮，

管道安裝(zhuang)在(zai)施工中難免會造成所安裝(zhuang)的(de)設備材(cai)料被(bei)損壞，為此必須加強思(si)想教育(yu)和現(xian)場督促，確實(shi)做好成品保護工作，減少不必要的(de)損失。

1.到場的(de)成品風管(guan)應放置在通風防潮地帶并分類按規格(ge)分區域堆放，且有明顯(xian)的(de)標識(shi)區分。

2.風管(guan)(guan)在(zai)安裝運輸(shu)過程中應輕拿輕放、嚴禁扔甩，避免(mian)碰撞，損壞(huai)風管(guan)(guan)，嚴禁用風管(guan)(guan)當(dang)作腳(jiao)手架和(he)吊設物件的(de)支架，風管(guan)(guan)被(bei)污染后應及時清(qing)理干(gan)凈。

3.到場(chang)的原材料(liao)如：角鋼、扁(bian)鋼、槽(cao)鋼、通(tong)(tong)絲螺桿(gan)、螺母等(deng)應按規格(ge)分(fen)類堆放在(zai)通(tong)(tong)風(feng)防(fang)潮(chao)地帶，型鋼、通(tong)(tong)絲螺桿(gan)等(deng)條(tiao)形材料(liao)應碼放整齊，防(fang)止產生彎(wan)曲變形。
