elbow）首先按它的曲率半徑來分，可分為長半徑彎頭和短半徑彎頭。長半徑彎頭指它的曲率半徑等于1.5倍的管子外徑，即R=1.5D。短半徑彎頭指它的曲率半徑等于管子外徑，即R=1.0D。（D為彎頭直徑，R為曲率半徑。D也可以用倍來表示。）若按壓力等級來分，大約有十七種，和美國的管子標(biāo)準(zhǔn)是相同的，有：Sch5s、Sch10s、Sch10、Sch20、Sch30、Sch40s、STD、Sch40、Sch60、Sch80s、XS；Sch80、Sch100、Sch120、Sch140、Sch160、XXS，其中相當(dāng)常用的是STD和XS兩種。按彎頭的角度分，有45°彎頭，有90°彎頭和180°彎頭。執(zhí)行標(biāo)準(zhǔn)有GB/T12459-2005、GB/T13401-2005、GB/T10752-1995、HG/T21635-1987、D-GD0219等。碳鋼彎頭加工</p><div

為什么碳鋼彎頭不能接觸水?你知道為什么碳鋼彎頭不能接觸水嗎?接下來小編就為我們簡略介紹一下。二氧化碳是水中存在較多的雜質(zhì)，通常情況下是以游離情況存在。水中存在的很多碳酸氫根在pH低時，也是以二氧化碳游離情況存在的，所以產(chǎn)生了碳酸平衡問題。此現(xiàn)象反應(yīng)式如下： </p> <p> CO2+H2O=H++HCO3-=2H++CO32- </p> <p> 因而，水中二氧化碳越多，生成H+越多，水的pH值越低，產(chǎn)生酸性的腐蝕性水，破壞了碳鋼外表生成的維護(hù)膜引起碳鋼腐蝕。其腐蝕的化學(xué)反應(yīng)如下： </p> <p> 2CO2+Fe(OH)2=Fe(HCO3)2 </p> <p> 4Fe(HCO3)2+O2+2H2O=4Fe(OH)3+8CO2 假如除鹽水中進(jìn)入二氧化碳，水的電導(dǎo)率即會上升，腐蝕性增大。因而除鹽水箱應(yīng)當(dāng)有避免大氣中二氧化碳溶入水箱的方法，如用N2或其他惰性氣體在水箱頂部空間進(jìn)行維護(hù)，可以避免二氧化碳污染純水水質(zhì)。二氧化碳是空氣中常見的化合物，碳與氧反應(yīng)生成其化學(xué)式為CO2，一個二氧化碳分子由兩個氧原子與一個碳原子通過共價鍵構(gòu)成，常溫下是一種無色無味氣體，密度比空氣大，能溶于水，與水反應(yīng)生成碳酸，不支持燃燒。固態(tài)二氧化碳壓縮后俗稱為干冰。二氧化碳不被認(rèn)為是加重溫室效應(yīng)的主要來歷。
