管材自動(dòng)噴水滅火系統(tǒng)和水噴霧滅火系統(tǒng)報(bào)警閥以前的管道、消火栓系統(tǒng)給水管，架空時(shí)應(yīng)采用內(nèi)外壁熱浸鍍鋅鋼管；埋地時(shí)應(yīng)采用球墨鑄鐵管，自動(dòng)噴水滅火系統(tǒng)和水噴霧滅火系統(tǒng)報(bào)警閥以后的管道可采用熱浸鍍鋅鋼管、銅管、不銹鋼管及鋼涂塑、不銹鋼襯塑等管道。 </p> <p> 2. 采用鋼管時(shí)壓力小于等于2MPA時(shí)，比較小壁厚有要求，詳技術(shù)措施P274。 </p> <p> 3. 熱浸鍍鋅焊接鋼管分為普通鋼管、加厚鋼管、和無(wú)縫鋼管，當(dāng)系統(tǒng)壓力小于等于1.0MPA時(shí)，可采用熱浸鍍鋅焊接鋼管；當(dāng)系統(tǒng)壓力在1.0-1.6間時(shí)，應(yīng)采用熱浸鍍鋅焊接加厚鋼管；當(dāng)系統(tǒng)壓力大于1，桂林世紀(jì)球墨鑄鐵管件.6時(shí)應(yīng)采用熱浸鍍鋅無(wú)縫鋼管。4. 當(dāng)噴頭為60度錐管螺紋時(shí)(NT)，宜采用熱浸鍍鋅無(wú)縫鋼管。 </p> <p> 5. 管道接口：卡箍連接、螺紋連接、法蘭和焊接。系統(tǒng)管道的連接鍍鋅鋼管應(yīng)采用槽式連接件(卡箍)，桂林世紀(jì)球墨鑄鐵管件，桂林世紀(jì)球墨鑄鐵管件、螺紋或法蘭連接。報(bào)警閥前采用內(nèi)壁不防腐鋼管時(shí)，可焊接連接。系統(tǒng)中管徑DN小于等于80時(shí)，采用螺紋連接，管徑DN大于80時(shí)，可采用卡箍連接、法蘭連接或焊接。因卡箍連接要求的施工空間小，便于維修，是目前比較好的連接方式。

<p> 離心球墨鑄鐵管的安裝步驟如下： </p> <p> 1。安裝準(zhǔn)備：在開(kāi)挖管網(wǎng)管溝前，首先要考慮回填時(shí)可將砂、砂填至管底，以保證應(yīng)力均勻。在接口處挖溝時(shí)，盡量留有相應(yīng)的操作空間，確保安裝連接時(shí)操作方便，施工安全。除特殊情況外，溝槽應(yīng)平直，溝槽底部應(yīng)在同一平面上。用機(jī)器挖溝時(shí)，溝底20cm-30cm厚的土層不宜臨時(shí)開(kāi)挖，應(yīng)人工清理至高程。 </p> <p> 2。用刷子和干凈的抹布清潔插座內(nèi)部和插座端的外表面。尤其是，橡膠密封件放置位置不得有石塊、泥土和沙子等異物。南寧濟(jì)鋼球墨鑄鐵管哪里好柳州球墨鑄鐵管企業(yè) 球墨鑄鐵供水管球墨鑄鐵管廠家報(bào)價(jià)。</p><div style="width:100%;text-align: center;"><img style="max-width:
