高溫(wen)預制直埋保(bao)溫(wen)管主(zhu)要由(you)四部分組(zu)成。
（1）工作鋼(gang)(gang)(gang)管(guan)：根據輸送介質的技術要求分別采用有(you)縫鋼(gang)(gang)(gang)管(guan)、無(wu)縫鋼(gang)(gang)(gang)管(guan)、雙面埋弧螺旋焊接鋼(gang)(gang)(gang)管(guan)。
（2）保溫(wen)層：采用硬質聚氨酯泡沫(mo)塑(su)料(liao)。
（3）保護殼：采(cai)用高密度聚乙烯或玻璃鋼。
（4）滲(shen)漏(lou)報(bao)(bao)警(jing)(jing)(jing)線：制(zhi)造高(gao)溫(wen)預(yu)制(zhi)直埋保(bao)溫(wen)管時，在靠(kao)近鋼管的(de)(de)保(bao)溫(wen)層中(zhong)，埋設有報(bao)(bao)警(jing)(jing)(jing)線，一(yi)旦管道某(mou)處發生(sheng)滲(shen)漏(lou)，通過(guo)警(jing)(jing)(jing)報(bao)(bao)線的(de)(de)傳導，便(bian)可在專用檢測儀(yi)表上報(bao)(bao)警(jing)(jing)(jing)并顯示出漏(lou)水的(de)(de)準確位置和滲(shen)漏(lou)程度(du)的(de)(de)大小，以便(bian)通知(zhi)檢修人員迅速處理(li)漏(lou)水的(de)(de)管段，保(bao)證熱網 運行。
