聚氨酯保溫管從裏到外分三層結構di一層：工作鋼管層 根據設計和客戶的要求一般選用無縫管(GB8163-87)螺旋焊管(GB9711-88;SY/T5038-92)和直縫焊管(GB3092-93)。鋼管表麵經過先進的拋除鏽工藝處理後，鋼管除鏽等級可達GB8923-1988標準中的Sa2級，表麵粗糙度可達GB6060.5-88標準中R=12.5微米二層：聚氨酯保溫層用高壓發泡機在鋼管於外護層之間形成的空腔中一次性注入硬質聚氨酯泡沫塑料原液而成。即俗稱的“管中管發泡工藝”。其作用一是防水，二是保溫，三是支撐熱網自重。當輸送介質溫度為：-50℃—120℃時，選用硬質聚氨ji脲酸酯泡沫塑料做保溫層。第三層：高密度聚乙烯保護層預製成一定壁厚的黑色(黃色)塑料管材，其作用一是保護聚氨酯保溫層免遭機械硬物破壞，二是防腐防水
產品結構形式：預製直埋蒸汽保溫管由蕊管(工作鋼管)減租層、隔熱層、反射層、緊固鋼帶、滑動支架、空氣層、外護鋼管、噴塗聚氨酯、纏繞玻璃鋼組成。特點：juanzhifapaobaowengangguanyonggangguanzuowaibaohuceng，juyouqiangdugao。buyisunhuaiqienengchengshoujiaodashangbuhezaidetedian，weidadaochangshouming，duigangwaitaoguanxujinxingfangfuchuli。gundongzhichijiegoushejiheli，gundongmocalixiao，gudingzhizuoshoulijianxiao，qilixuefenxiyuanlijiandan，guandaowendingxing、安全性得到較大提高。真空層徹底杜絕了空氣層存在的熱傳導和熱對流、極大地降低了熱損失。與空氣層結構相比，在同等保溫厚度下可降低外壁溫度8-13°c。抽真空裝置徹底解決了外鋼套管內壁容易被熱濕空氣腐蝕的難題，大大提高了直埋蒸汽管道的運行壽命。產品壽命提高到30年。
高溫預製直埋保溫管是一種保溫性能好，加安全可靠，工程造價低的直埋預製保溫管。有效的解決了城鎮集中供熱中130℃－600℃高溫輸熱用預製直埋保溫管的保溫、滑動潤滑和裸露管端的防水問題。高溫預製直埋保溫管不僅具有傳統地溝和架空敷設管道難以比擬的先進技術、shiyongxingneng，erqiehaijuyouxianzhudeshehuixiaoyihejingjixiaoyi，yeshigongrejienengdeyoulicuoshi。gaowenyuzhizhimaibaowenguanyouyujuanzhiyingzhipaomobaowencengjinmidizhanjiezaigangguanwaipi，gejuelekongqiheshuideshenru，nengqidaolianghaodefangfuzuoyong。tongshitadefapaokongdoushibihede，xishuixinghenxiao。juanzhibaowenguangaomidujuyixiwaike、聚氨酯保溫管玻璃鋼外殼均具有良好的防腐、絕jue緣yuan和he機ji械xie性xing能neng。因yin此ci，工gong作zuo鋼gang管guan外wai皮pi很hen難nan受shou到dao外wai界jie空kong氣qi和he水shui的de侵qin蝕shi。隻zhi要yao管guan道dao內nei部bu水shui質zhi處chu理li好hao，據ju國guo外wai資zi料liao介jie紹shao，高gao溫wen預yu製zhi直zhi埋mai保bao溫wen管guan的de使shi用yong壽shou命ming可ke達da50年以上，比傳統的地溝敷設、架空敷設使用壽命高3~4倍。
