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。廈門常達管業(yè)有限公司成立于2015年4月，座落于美麗的廈門，主營銷售不銹鋼管、PSP鋼塑復合壓力管、離心球墨鑄鐵管及配套管件、鑄造制品等相關業(yè)務。公司為客戶提供***的球墨鑄鐵管道系統(tǒng)，和各大管道品牌有著良好而深遠的合作，擁有豐富的產(chǎn)品種類，能為客戶提供品種齊全的管道及管件。廈門球墨鑄鐵管廠家球墨鑄鐵管有什么需要了解的嗎？</p><div

球墨鑄鐵管的施工和安裝注意問題：在開溝前，先***障礙，平整地面。然后按照設計要求擺放球墨鑄鐵管，并采取適當?shù)姆雷o措施防止管節(jié)滾落。當管基鋪設完砂墊層后，根據(jù)沿管溝已排放好的球墨鑄鐵管實際長度，開挖接口工作坑，確保管身整體穩(wěn)定在砂墊層上。根據(jù)設計用觀測器、水平儀找準安裝面。溝底應規(guī)矩整齊，要防止把管子放在底層石塊的凸面上。一般情況下，水流方向應從承口流向插口；但在坡度很大的情況下，要把承口朝上，安裝時從下往上進行。盡量避免承口向插口安裝。放管下溝時，要避免與底部和壁面強烈碰撞。用毛刷和干凈的抹布清理承口內(nèi)部，對較小規(guī)格的橡膠密封圈，將其弄成“心”型放入承口密封槽內(nèi)，對較大規(guī)格的橡膠密封圈，將其彎成“十”型或其它形狀。清掃插口、光滑邊緣，要用**潤滑劑潤滑膠圈和插口，連接球墨鑄鐵管時，對不同管徑的球墨鑄鐵管應采用不同的工具。

鑄鐵是含碳量大于百分之二點一一的鐵碳合金，由工業(yè)生鐵、廢鋼等鋼鐵及其合金材料經(jīng)過高溫熔融和鑄造成型而取得，除Fe外，還含及其它鑄鐵中的碳以石墨形態(tài)析出，若析出的石墨呈條片狀時的鑄鐵叫灰口鑄鐵或灰鑄鐵、呈蠕蟲狀時的鑄鐵叫蠕墨鑄鐵、呈團絮狀時的鑄鐵叫白口鑄鐵或碼鐵、而呈球狀時的鑄鐵就叫球墨鑄鐵。球墨鑄鐵除鐵外的化學成分通常為：含碳量百分之三到百分之四，含硅量百分之一點八到百分之三點二，含錳、磷、硫總量不超過百分之三和適量的稀土、鎂等球化元素。

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、責任心等影響較大，施工方面不如PE管便捷.但是球墨鑄鐵管具有**度、耐高壓、使用時間長的特點。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。
