聚氨酯直埋保溫(wen)鋼管(guan)由輸(shu)送介(jie)質的，工作鋼管(guan)、聚氨酯保溫(wen)層(ceng)、聚乙烯(xi)塑料(liao)外護(hu)管(guan)，通(tong)過設備依次向外結(jie)合而成。

聚(ju)氨酯直埋(mai)保溫(wen)(wen)鋼管較之傳(chuan)統的各類保溫(wen)(wen)管材具(ju)有(you)十分(fen)突出(chu)的優點：

1、保(bao)溫性能好，熱損失僅(jin)為傳統管(guan)材的25%，長期(qi)運行可節約大量能源(yuan)(yuan)，顯著降低能源(yuan)(yuan)成本。

2、具有很強的(de)防水和耐腐蝕能力(li)，不需附設管溝，可直接(jie)埋入地下(xia)或(huo)水中，施工簡便迅速，綜合造價低。

3、在低溫條件下也具有良好的耐腐蝕和耐沖擊性，可直接埋入地下凍土(tu)。

4、使(shi)用(yong)(yong)(yong)壽命(ming)可(ke)達(da)30-50年，正確(que)的(de)安(an)裝和(he)使(shi)用(yong)(yong)(yong)可(ke)使(shi)管網維修費(fei)用(yong)(yong)(yong)極低(di)。
