高溫蒸汽保溫管(guan)價格

高溫蒸汽保(bao)溫管價格結(jie)構：

可(ke)分為內(nei)(nei)滑(hua)(hua)動(dong)式(shi)(shi)(shi)和外(wai)滑(hua)(hua)動(dong)式(shi)(shi)(shi)兩種(zhong)結(jie)構。內(nei)(nei)滑(hua)(hua)動(dong)式(shi)(shi)(shi)直(zhi)埋蒸汽保(bao)(bao)溫(wen)(wen)管(guan)，保(bao)(bao)溫(wen)(wen)材(cai)(cai)料(liao)(liao)和外(wai)護管(guan)相對不動(dong)，主要為工(gong)作鋼(gang)(gang)管(guan)收熱力膨脹在(zai)保(bao)(bao)溫(wen)(wen)材(cai)(cai)料(liao)(liao)中移動(dong)。該結(jie)構適合于硬質保(bao)(bao)溫(wen)(wen)材(cai)(cai)料(liao)(liao)中，優點(dian)為工(gong)作鋼(gang)(gang)管(guan)與外(wai)護管(guan)間無(wu)需設置支撐環，外(wai)護管(guan)內(nei)(nei)壁不易被腐蝕，但缺點(dian)是(shi)易造成保(bao)(bao)溫(wen)(wen)材(cai)(cai)料(liao)(liao)的偏心和壓碎。外(wai)滑(hua)(hua)動(dong)式(shi)(shi)(shi)鋼(gang)(gang)套鋼(gang)(gang)保(bao)(bao)溫(wen)(wen)管(guan)，滑(hua)(hua)動(dong)面(mian)在(zai)外(wai)護管(guan)內(nei)(nei)表面(mian)，保(bao)(bao)溫(wen)(wen)材(cai)(cai)料(liao)(liao)隨工(gong)作鋼(gang)(gang)管(guan)一起運動(dong)。

蒸汽直埋保(bao)(bao)溫(wen)管(guan)該(gai)結構適用(yong)于軟質(zhi)保(bao)(bao)溫(wen)材料中(zhong)，優(you)點為保(bao)(bao)證熱流(liu)不外(wai)泄，解決(jue)了由于徑向膨脹造成摩擦力(li)增大問題，而且內(nei)部有支撐環，不會(hui)造成保(bao)(bao)溫(wen)材料的偏心和壓碎。根據設計和要求，鋼(gang)(gang)套(tao)鋼(gang)(gang)保(bao)(bao)溫(wen)管(guan)外(wai)護層可(ke)進行三層PE、環氧煤瀝青(qing)或玻璃鋼(gang)(gang)等防腐技術措施，防止鋼(gang)(gang)管(guan)腐蝕(shi)。
