4、傳統(tǒng)的灰鑄鐵管由于材料脆，強(qiáng)度和韌性較低，使用機(jī)械接口，不能承受更高的使用內(nèi)部和外部負(fù)載，使用時(shí)無法承受較高的內(nèi)、外載荷，經(jīng)常不可避免地發(fā)生爆、豁、斷、裂等現(xiàn)象，遇到地質(zhì)條件、外載條件變化時(shí)，容易發(fā)生管體脆斷、錯(cuò)位事故，并產(chǎn)生泄漏，現(xiàn)在已基本退出市場(chǎng)。

6、而鋼管耐蝕性差，使用壽命短，施工項(xiàng)目相對(duì)復(fù)雜，成本高，也逐漸退出了供水管網(wǎng)市場(chǎng)。廠家直銷蘭州國(guó)標(biāo)球墨鑄鐵管排污用球墨鑄鐵管各種規(guī)格大量現(xiàn)貨。南寧排水球墨鑄鐵管新報(bào)價(jià)</p><p
