17、管網(wǎng)安裝：自動(dòng)噴水滅火系統(tǒng)管材應(yīng)根據(jù)設(shè)計(jì)要求選用，一般采用鍍鋅鋼管及管件，當(dāng)管子公稱直徑小于或等于100mm時(shí)，應(yīng)采用螺紋連接；當(dāng)管子公稱直徑大于100mm時(shí)，可采用法蘭連接和焊接，焊口內(nèi)外表面場(chǎng)作好防腐。管道安裝前應(yīng)校直管子并清除內(nèi)部雜物，停止安裝時(shí)已安裝的管道敞口應(yīng)封堵好。如需在鍍鋅管上開(kāi)孔焊接時(shí)應(yīng)提前預(yù)制，必要時(shí)管道兩端采用法蘭活接，焊接后做完清理防腐再安裝。嚴(yán)禁在已安裝好的鍍鋅管道上開(kāi)孔施焊。管道穿過(guò)伸縮縫時(shí)應(yīng)設(shè)置柔性短管，管道

18、水平安裝宜設(shè)0.002～0.005的坡度，坡向泄水裝置。1.1.1干管安裝：干管安裝：噴灑干管用法蘭連接，每根配管長(zhǎng)度不宜超過(guò)6m，直管段可把幾根連接在一起使用倒鏈安裝，但不宜過(guò)長(zhǎng)。也可調(diào)直后編號(hào)依順序安裝，吊裝時(shí)應(yīng)先吊起管道一端，待穩(wěn)定后再吊起另一端。管道連接緊固法蘭時(shí)，檢查法蘭端面是否干凈。采用3～5mm的橡膠墊片。法蘭螺栓的規(guī)格應(yīng)符合規(guī)定。緊固螺栓應(yīng)先緊固最不利點(diǎn)，然后依次對(duì)稱緊固。法蘭接口應(yīng)安裝在易拆裝的位置。水平安裝管道的卡架
