style="text-indent:25px">球墨鑄鐵管是鑄鐵管的一種。質(zhì)量上要求鑄鐵管的球化等級(jí)控制為1-3級(jí)（球化率》80%），因而材料本身的機(jī)械性能得到了較好的改善，具有鐵的本質(zhì)、鋼的性能。退火后的球墨鑄鐵管，其金相組織為鐵素體加少量珠光體，機(jī)械性能良好，防腐性能優(yōu)異、延展性能好，密封效果好，安裝簡(jiǎn)易、主要用于市政、工礦企業(yè)給水、輸氣，輸油等。在鐵素體和珠光體基體上分布有一定數(shù)量的球狀石墨，根據(jù)公稱口徑及對(duì)延伸率的要求不同，基體組織中的鐵素體和珠光體的比例有所不同，小口徑的珠光體比例一般不大于**口徑的一般控制在25%左右。球墨管發(fā)展歷史：1947年英國(guó)H.Morrogh發(fā)現(xiàn)，在過(guò)共晶灰口鑄鐵中附加鈰，使其含量在0.02wt%以上時(shí)，石墨呈球狀。南寧球墨管價(jià)格廣西球墨鑄鐵管現(xiàn)貨報(bào)價(jià)

球墨鑄鐵管的缺點(diǎn)：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(diǎn)：PE管具有良好的耐腐蝕性其抗無(wú)機(jī)物性能比金屬管強(qiáng)得多，在埋地敷設(shè)時(shí)不需要防腐,施工方便。小口徑PE管在性能價(jià)格比上優(yōu)于鋼管和球墨鑄鐵管.PE管得缺點(diǎn)：苯、汽油、四氯化碳等有機(jī)溶劑對(duì)聚乙烯有一定得影響。有機(jī)溶劑如果滲入聚乙烯內(nèi)，會(huì)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. </p> <p> 球墨鑄鐵管和PE管對(duì)比優(yōu)缺點(diǎn)！ </p> <p> <br /> </p><p> 球墨鑄鐵管性能優(yōu)良，球墨鑄鐵管的力學(xué)性能高于焊鋼管。它能忍受高壓，方便修筑、檢驗(yàn)和保障。同時(shí)，球墨鑄鐵管的耐腐蝕性能高于焊鋼管，埋地使用壽命是鋼管的兩倍超過(guò)。由此可見(jiàn)，稀土球墨鑄鐵管是確保水管質(zhì)量潛力的必要條件。球墨鑄鐵管是在原材料鐵水中退出稀土等元素，使鐵水獲得凈化，同時(shí)使鐵水上墨，提升鑄鐵管的抗壓強(qiáng)度、硬度、塑性和延伸率，耐壓和抗影響性能可提升鑄鐵管的質(zhì)量，確保其在更嚴(yán)峻的環(huán)境之中采用，是一般灰鑄鐵管使用壽命的幾倍。 </p> <p> 球墨鑄鐵管中石墨呈球形適用，石墨粒徑為6-7。在質(zhì)量方面，建議鑄鐵管球化等級(jí)掌控在1-3級(jí)，球化率≥80%。不銹鋼鋼管的本質(zhì)是球墨鑄鐵管，隨著鐵的性質(zhì)和鋼的性能的提高，材料本身的力學(xué)性能獲得了較糟糕的改善。退火球墨鑄鐵管的金相組織為鐵素體和少量珠光體。它具備不錯(cuò)的力學(xué)性能，所以又稱鑄鐵管。廣西供水球墨鑄鐵管廠家供應(yīng)DN350球墨鑄鐵管廠家。</p><div
