Pipe)，用鑄鐵澆鑄成型的管子。鑄鐵管用于給水、排水和煤氣輸送管線，它包括鑄鐵直管和管件。勞動強度小。按鑄造方法不同，分為連續(xù)鑄鐵管和離心鑄鐵管，其中離心鑄鐵管又分為砂型和金屬型兩種。 </p> <p> 目前，惠民縣水利局本著先急后緩的原則，對武定府路和環(huán)城南路管網(wǎng)進行升級改造，此次管網(wǎng)改造提升項目中的供水主管道和分支管道全部使用球墨鑄鐵管和PE管，這兩種材質(zhì)具有強度高、耐腐蝕和重量輕等特點。球墨鑄鐵管價格多少錢一米？球墨鑄鐵管目前的市場走勢不容樂觀，雖然國內(nèi)球墨管的供給在快速增加，但是對市場要求的檢測卻非常滯后。如果遇到市場逆轉(zhuǎn)，產(chǎn)量過剩問題就顯露無遺。

球墨鑄鐵管的缺點：球墨鑄鐵管的連接受人為因素如操作水平、責(zé)任心等影響較大，施工方面不如PE管便捷.PE管的優(yōu)點：PE管具有良好的耐腐蝕性其抗無機物性能比金屬管強得多，在埋地敷設(shè)時不需要防腐,施工方便。小口徑PE管在性能價格比上優(yōu)于鋼管和球墨鑄鐵管.PE管得缺點：苯、汽油、四氯化碳等有機溶劑對聚乙烯有一定得影響。有機溶劑如果滲入聚乙烯內(nèi)，會出現(xiàn)溶脹現(xiàn)象，其物理性能就下降，其耐壓性、耐溫度變化性能較差.
