直埋供熱管道不需要砌築龐大的地溝，隻需將保溫管埋人地下，因此大大減少了工程占地，減少土方開挖量約50%以上，減少土建砌築和混凝土量90%。同時，保溫管加工和現場挖溝平行進行，隻需現場接頭

，可以縮短工期約50%以上,預製直埋保溫管廣泛用於液體


、氣體的輸送管網，化工管道保溫工程石油、化工
、集中供熱熱網
、中央空調通風管道、市政工程等。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。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、實shi用yong性xing能neng，而er且qie還hai具ju有you顯xian著zhu的de社she會hui效xiao益yi和he經jing濟ji效xiao益yi，也ye是shi供gong熱re節jie能neng的de有you力li措cuo施shi。預yu製zhi直zhi埋mai保bao溫wen管guan采cai用yong直zhi埋mai供gong熱re管guan道dao技ji術shu，標biao誌zhi著zhe中zhong國guo供gong熱re聚ju氨an酯zhi保bao溫wen管guan技ji術shu發fa展zhan已yi經jing進jin入ru了le新xin的de起qi點dian。

、防腐。當輸送介質的溫度t≤130℃時

，保溫層用發泡聚氨脂，外套管用塑膠或玻璃鋼的居多，對當輸送介質的溫度高於130℃時，保溫層一般用礦物纖維，外套管用鋼管

，這實際上是一條鋼地溝。
