鋼(gang)襯玻(bo)(bo)璃(li)管(guan)(guan)(guan)道是鋼(gang)管(guan)(guan)(guan)、管(guan)(guan)(guan)件與(yu)玻(bo)(bo)璃(li)的復(fu)合體，是將熔(rong)融(rong)的玻(bo)(bo)璃(li)以吹制(zhi)法襯在(zai)經過焙燒預熱的碳(tan)鋼(gang)管(guan)(guan)(guan)或(huo)管(guan)(guan)(guan)件內(nei)壁，使(shi)玻(bo)(bo)璃(li)牢固(gu)地黏附在(zai)管(guan)(guan)(guan)子、管(guan)(guan)(guan)件的內(nei)壁上，并處于(yu)一(yi)定的壓縮狀態。除吹制(zhi)法外，還有膨脹法及噴涂法。

  吹制襯玻(bo)璃(li)管(guan)道使(shi)(shi)(shi)用(yong)(yong)溫度(du)為0～150℃，使(shi)(shi)(shi)用(yong)(yong)壓力小(xiao)于或等于0.6MPa，冷沖擊ΔT＝80℃，熱沖擊ΔT＝120℃，使(shi)(shi)(shi)用(yong)(yong)介(jie)質與玻(bo)璃(li)管(guan)道相(xiang)同。

  應用實例有稀硫酸（100℃）管線，EDTA輸送(song)管線，苯烴(jing)液化介質（HCl，105℃），橡膠膠漿輸送(song)管線（易堵）等。
