style="text-indent:25px">氣體管道安裝的注意事項1、管道連接時，嚴(yán)禁強(qiáng)力對口。管子與設(shè)備的連接，應(yīng)在設(shè)備安裝定位緊好地腳螺栓后自然地進(jìn)行。2、管道安裝若采用組合方式時，組合件應(yīng)具備足夠剛性，吊裝后不應(yīng)產(chǎn)生變形，臨時固定應(yīng)牢固可靠。3、在管線上因安裝儀表插座、疏水管座等需開孔、且孔徑小于30mm時，不得用氣割開孔。4、管道安裝時，注意管子與管子之間應(yīng)有一定的間距，相互不得接觸，也不得與基礎(chǔ)或設(shè)備之任何零件相碰，并應(yīng)留有足夠的距離，留作管道膨脹及敷設(shè)保溫材料之用。5、根據(jù)設(shè)計圖紙在管道上應(yīng)開的孔洞，宜在管子安裝前開好。開孔后須將管道內(nèi)部清理干凈，不得遺留鉆屑或其它雜物，嚴(yán)禁汽割及角向磨光機(jī)進(jìn)行開孔。6、對于大直徑焊接鋼管，管子對口時，應(yīng)保證其縱向焊縫相互錯開不少于100mm，并宜處于容易檢查的部位。7、支吊架安裝工作宜與管道的安裝工作同步進(jìn)行。支吊架的形式和安裝位置須嚴(yán)格遵照設(shè)計規(guī)定。管道的支吊架可參照國標(biāo)05R417-1中的各種形式并結(jié)合現(xiàn)場情況制作安裝。嚴(yán)禁用氧氣吹刷管道或用氧氣試漏、試壓。廣州氨氣管道施工公司</p><p

style="text-indent:25px">乙炔氣與空氣、氧氣混合達(dá)到一定容積比時遇火即會。乙炔氣與許多有色金屬(銅、銀、汞、鋅、鎘等)相互作用產(chǎn)生易爆的金屬碳化物，其中與銅的碳化物具有較大的性。因此，安裝乙炔管道需特別注意施工時與通氣后的防爆問題。管道材料選用。乙炔管道應(yīng)選用無縫鋼管、不銹鋼管或鋼塑復(fù)合管。乙炔管道系統(tǒng)的計器、儀表、閥門與管件等應(yīng)選用鋼制或鑄鐵制品，不得選用銅制品(可選用含銅量低于70％的銅合金制品)；閥門內(nèi)閥芯與閥瓣應(yīng)采用不銹鋼、皮革制成，以保證閥門開關(guān)時不發(fā)生火花。儀表檢查箱上應(yīng)注明“乙炔”、“禁火”字樣。深圳氨氣管道施工設(shè)計</p></p><br
