耐磨管件的應用

　　耐磨管道主要包括耐磨彎頭、直管、三通、大小頭、方圓節、變徑管等結構件，主要用于氣力、泵送漿體等物料輸送管道。耐磨管道使用范圍：

　　主要應用于：燃煤電廠(chǎng)除灰、排渣管、送粉、回粉管，脫硫管道外;

　　礦山：煤炭工業(yè)中水煤漿、洗煤泥、礦山充填料、礦煤粉;

　　金屬礦山：精礦和尾礦的輸送耐磨彎頭;

　　冶金：鋼鐵廠(chǎng)的煉鐵的高爐噴煤、輸渣等管道;

　　 CAO、鋅碚砂輸送管道，煉鋼的輸送鐵合金、爐外精煉等優(yōu)選的耐磨彎頭;

　　水泥廠(chǎng)：旋窯濕法生產(chǎn)線(xiàn)的生料漿輸送、煤粉輸送、提升機的下料、成品水泥氣力輸送裝卸，混凝土輸送耐磨彎頭。

　　化工廠(chǎng)：煤粉輸送管道，硅粉等原料輸送耐磨彎頭

　　耐磨管道與傳統的鋼管、耐磨合金鑄鋼管、鑄石管以及鋼塑、鋼橡管等有著(zhù)本質(zhì)性區別。耐磨管道外層是無(wú)縫鋼管，內層是剛玉。剛玉層硬度高達HV1100-1400，相當于鎢鈷硬質(zhì)合金，耐磨性比碳鋼管高20倍以上。耐磨管道抗磨損主要是靠?jì)葘訋缀撩缀竦膭傆駥?，這比耐磨合金鑄鋼管、鑄石管既靠成分和組織，又靠厚度來(lái)抗磨已經(jīng)有了質(zhì)的飛躍。
