**近有輸水管道業(yè)內(nèi)人士傳給我一份新興鑄管寫的《球管與鋼管的技術(shù)比較》，期間我還在網(wǎng)上看了兩個(gè)新興鑄管的PPT，《球墨鑄鐵管與鋼管比較》和《球管以PCCP管的比較》。本來認(rèn)為這些材料是企業(yè)的市場(chǎng)宣傳，管道工程技術(shù)人員在設(shè)計(jì)管道時(shí)會(huì)理性判斷，正確加以選擇。其實(shí)不然，很多業(yè)內(nèi)專業(yè)人士甚至認(rèn)可這其中的觀點(diǎn)，因此，本人認(rèn)為有必要與新興鑄管商榷，澄清幾個(gè)有關(guān)的說法和問題。1?球墨鑄鐵管在歐美地區(qū)使用比例達(dá)到90%以上輸水鋼管在北美使用超過160年，1858年***條輸水鋼管安裝在加州當(dāng)時(shí)的淘金地區(qū)，這條水管用鉚接鋼管制成，直徑為280－560mm，壁厚。這條輸水鋼管一直使用到1970年代，壽命超過100年。***條焊接輸水鋼管于1926年生產(chǎn)，管道長(zhǎng)近130Km，管徑1549－1651mm，當(dāng)時(shí)由加州東灣水務(wù)局安裝在莫?jiǎng)P勒米水道。到了1940年，美國(guó)大概安裝有5630Km長(zhǎng)的輸水鋼管。1970年代有差不多8850Km長(zhǎng)的輸水鋼管在使用。北美大口徑輸水管道市場(chǎng)主要是由螺旋焊管提供，其它還包括鋼筒混凝土壓力管（PCCP），球墨鑄鐵管的份額很少。球墨鑄鐵管通常在DN600或DN800以下口徑相對(duì)鋼管有成本優(yōu)勢(shì)，因此口徑超過DN1000以上的球墨鑄鐵管在歐美國(guó)家很少。阿勒泰離心球墨鑄鐵管銷售廠家。</p><div
