我們的生活中離不開水，不論是吃的還是用的，**常見的就是自來水了吧。不知道你曾經(jīng)是否思考過自來水的輸送問題，那么，自來水管道的主要材料是什么呢？它又具有怎樣的特性來保證水質(zhì)的安全性和運(yùn)輸?shù)陌踩阅?？它就?**要來介紹的主體—球墨鑄鐵管，下面小編就對(duì)于什么是球墨鑄鐵管做簡單介紹。首先，我們來了解一下什么是球墨鑄鐵管，球墨鑄鐵管是使用18號(hào)以上的鑄造鐵水在添加球化劑后，經(jīng)過離心球墨鑄鐵機(jī)高速離心后鑄造而成的管材，簡稱球管、球鐵管以及球墨鑄管等，其主要成分有碳、硅、錳、硫、磷和鎂等。球墨鑄鐵管也是自來水管道的理想選材，主要用途自然是輸送自來水。在我國很多地區(qū)，球墨鑄鐵管在中、小口徑的管與管之間的聯(lián)接，主要采用承式或法蘭盤式接口方法；而且球墨鑄鐵，容許限制的轉(zhuǎn)角必須有***的抗震性和密封性。其次，我們必須要知道球墨鑄鐵管有什么樣的特點(diǎn)，顧名思義，球墨鑄鐵管是鑄鐵管中的一種，在質(zhì)量上要求鑄鐵管的球化等級(jí)控制為1-3級(jí)，即球化率不小于80%，所以球墨鑄鐵管材料本身的機(jī)械性就可以得到比較好的改善，從而具有鐵的本質(zhì)和鋼的性能。在退火后，球墨鑄鐵管金相組織為鐵素體加上少量的珠光體，使得具有機(jī)械性能良好。烏魯木齊球墨鑄鐵管規(guī)格阿勒泰專業(yè)球墨鑄鐵管廠家直供。</p><div

根據(jù)需要還可以在管端加工承插接口，與國內(nèi)輸水鋼管相比，其特點(diǎn)是減壁，防腐和接口。這三方面是我國輸水鋼管今后的發(fā)展方向?？上驳氖?，國內(nèi)目前借鑒油氣管道的技術(shù)開始采用高分子聚合材料進(jìn)行內(nèi)外防腐，并且開發(fā)了多種承插接口用于輸水管道領(lǐng)域?；氐叫屡d鑄管的第4點(diǎn)說法，實(shí)際工程設(shè)計(jì)中并不是所有場(chǎng)合都適用承插柔型連接（非限制性接口），即使是承插連接的管道，間隔一定距離須設(shè)置止推支墩來限制位移防止管節(jié)脫扣，或者采用限制性接口（鑄鐵管的自錨接口）進(jìn)行管道連接（參看上圖）。行業(yè)內(nèi)流行的另一種說法是柔性承插接口抗震性能高，并且用汶川地震后的球墨鑄鐵管照片（下圖）做注解。實(shí)際上，強(qiáng)震會(huì)破壞承插柔性接口，設(shè)計(jì)規(guī)范要求選用材料強(qiáng)度和韌性好的管材，采用剛性連接，從這點(diǎn)來看，由于鋼管優(yōu)越的梁強(qiáng)度，采用鋼管和焊接連接是合適的。在強(qiáng)震多發(fā)地區(qū)須選用限制性接口，日本在鑄鐵管自錨接口的研發(fā)方面處于世界前列?？偨Y(jié)球墨鑄鐵管的兩個(gè)主要優(yōu)勢(shì)是小口徑成本低和商品化的庫存生產(chǎn)。與鋼管相比，口徑DN600及以下球墨鑄鐵管比鋼管便宜；由于是按照管徑系列做庫存生產(chǎn)，對(duì)于應(yīng)急管道敷設(shè)和修復(fù)反應(yīng)迅速。對(duì)于大口徑輸水管道來講。</p><p> 一、球墨鑄鐵的概念球墨鑄鐵是通過球化和孕育處理得到的球狀石墨，有效地提高了鑄鐵的機(jī)械性能，特別是提高了塑性和韌性，從而得到比碳鋼還高的強(qiáng)度。球墨鑄鐵是20世紀(jì)五十年代發(fā)展起來的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)異的性能，已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性、耐磨性要求較高的零件。球墨鑄鐵已迅速發(fā)展為僅次于灰鑄鐵的、應(yīng)用十分***的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。二、成分生鐵是含碳量大于2％的鐵碳合金，工業(yè)生鐵含碳量一般在，并含C、SI、Mn、S、P等元素，是用鐵礦石經(jīng)高爐冶煉的產(chǎn)品。根據(jù)生鐵里碳存在形態(tài)的不同，又可分為---煉鋼生鐵、鑄造生鐵和球墨鑄鐵等幾種。析出的石墨呈球形的鑄鐵。球狀石墨對(duì)金屬基體的割裂作用比片狀石墨小，使鑄鐵的強(qiáng)度達(dá)到基體組織強(qiáng)度的70～90％，抗拉強(qiáng)度可達(dá)120kgf/mm2，并且具有良好的韌性。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量～％，含硅量～％，含錳、磷、硫總量不超過％和適量的稀土、鎂等球化劑。三、性能球鐵鑄件差不多已在所有主要工業(yè)部門中得到應(yīng)用，這些部門要求高的強(qiáng)度、塑性、韌性、耐磨性、耐嚴(yán)重的熱和機(jī)械沖擊、耐高溫或低溫、耐腐蝕以及尺寸穩(wěn)定性等。阿克蘇球墨鑄鐵搶修節(jié)銷售廠家。</p><div
