詳細(xì)介紹

　　高溫預(yù)制直埋保溫管主要由四部分組成。

　　(1)工作鋼管：根據(jù)輸送介質(zhì)的技術(shù)要求分別采用有縫鋼管、無(wú)縫鋼管、雙面埋弧螺旋焊接鋼管。

　　(2)保溫層：采用硬質(zhì)聚氨酯泡沫塑料。

　　(3)保護(hù)殼：采用高密度聚乙烯或玻璃鋼。

　　(4)滲漏報(bào)警線：制造高溫預(yù)制直埋保溫管時(shí)，在靠近鋼管的保溫層中，埋設(shè)有報(bào)警線，一旦管道某處發(fā)生滲漏，通過(guò)警報(bào)線的傳導(dǎo)，便可在檢測(cè)儀表上報(bào)警并顯示出漏水的準(zhǔn)確位置和滲漏程度的大小，以便通知檢修人員迅速處理漏水的管段，保證熱網(wǎng)安全運(yùn)行。

　　保溫管的特點(diǎn)：

　　高溫預(yù)制直埋保溫管-優(yōu)勢(shì)特點(diǎn)

　　1 具有很強(qiáng)的耐腐蝕和防水能力，綜合造價(jià)低據(jù)有關(guān)部門測(cè)算，雙管制供熱管道，一般情況下可以降低工程造價(jià)的25%(采用玻璃鋼做保護(hù)層)和10%(采用高密度聚乙烯做保護(hù)層)左右。

　　2 熱損耗低，節(jié)約能源。熱損耗僅為傳統(tǒng)管材的25% 　　直埋保溫管導(dǎo)熱系數(shù) 0.022kcal/m.h.℃ 憎水率 0.03kg/cm3

　　3 使用壽命長(zhǎng) 正確的安裝和使用可使管網(wǎng)壽命達(dá)到30-50年，而且維護(hù)費(fèi)用極低。

　　4 占地少施工快有利于環(huán)境保護(hù) 能減少土方開挖量50%以上減少土建砌筑和混凝土量90%
