根據(jù)需要還可以在管端加工承插接口，與國(guó)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(guó)輸水鋼管今后的發(fā)展方向。可喜的是，國(guó)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。回到新興鑄管的第4點(diǎn)說(shuō)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(lái)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(shuō)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(lái)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。總結(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(kù)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(kù)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(lái)講。</p><p>
