預(yù)制直埋保溫管是一種由工作鋼管、保溫層和外護(hù)管組成的保溫管道，其工作原理是利用熱傳導(dǎo)和熱輻射來(lái)傳遞熱量，以達(dá)到保溫和節(jié)能的目的。預(yù)制直埋保溫管的特點(diǎn)：1.高效保溫：采用聚氨酯等高效保溫材料，具有良好的保溫性能，能夠有效降低能源消耗。2.耐腐蝕：外護(hù)管采用高密度聚乙烯等材料，具有良好的耐腐蝕性能，能夠延長(zhǎng)管道的使用壽命。3.防水性能好：外護(hù)管采用密封圈連接，具有良好的防水性能，能夠有效防止水滲入保溫層。4.施工方便：預(yù)制直埋保溫管在工廠內(nèi)完成制作，現(xiàn)場(chǎng)施工方便快捷，能夠縮短工期。5.環(huán)保節(jié)能：采用環(huán)保材料和節(jié)能技術(shù)，符合國(guó)家相關(guān)標(biāo)準(zhǔn)和規(guī)定。預(yù)制直埋保溫管的應(yīng)用：預(yù)制直埋保溫管廣泛應(yīng)用于城市集中供熱、空調(diào)制冷、石油化工等領(lǐng)域，可用于輸送熱水、蒸汽、熱油等介質(zhì)，具有廣泛的應(yīng)用前景。

Pre-fabricated direct buried insulation pipes are made up of a working steel pipe, insulation layer, and external casing. They are designed to conserve heat and reduce energy losses through the use of heat conduction and radiation.Characteristics of Pre-fabricated Direct Buried Insulation Pipes:Highly efficient insulation: Using materials like polyurethane, which provideexcellentheatretention, these pipes help reduce energy consumption.Corrosion resistance: The external casing is made from materials like high-density polyethylene, providing resistance to various corrosive elements and extending the lifespan of the pipe.Good water resistance: The external casing features a sealing ring connection, effectively preventing water from seeping into the insulation layer.Convenient installation: As these pipes are pre-fabricated in the factory, installation on site is quick and easy, reducing construction time.Environmental friendliness: Made with environmentally friendly materials and energy-saving technologies, these pipes comply with national standards and regulations.Applications of Pre-fabricated Direct Buried Insulation Pipes:Used widely in urban central heating, air conditioning and refrigeration, petrochemical industries, these pipes can be used to transport media such as hot water, steam, hot oil, making them versatile in various applications.
