聚氨酯保溫管，全稱：高密度聚乙烯塑料外護(hù)聚氨酯泡沫預(yù)制直埋保溫管，由輸送介質(zhì)的工作鋼管、聚氨酯保溫層、聚乙烯塑料外護(hù)管，通過設(shè)備依次向外結(jié)合而成。高密度聚乙烯塑料外護(hù)聚氨酯泡沫預(yù)制直埋保溫管以其優(yōu)良的性能，方便的施工及使用年限長(30年-50年）而倍受人們歡迎，其結(jié)構(gòu)為:外保護(hù)層、保溫層、防滲漏層三部分，外保護(hù)層材料為聚乙烯夾克管或玻璃鋼或其它材料。敷設(shè)方式有直埋、架空、地溝三種方式。在中小口徑的熱輸或供暖管道上，為了減少管道向土壤散熱，在管道外部加上保溫復(fù)合層。常用的保溫材料是硬質(zhì)聚氨脂泡沫塑料，適用溫度為－185～120℃。這種材料質(zhì)地松軟，為提高其強(qiáng)度，在隔熱層外面加敷一層高密度聚乙烯層，形成復(fù)合材料結(jié)構(gòu)，以防止地下水滲入保溫層內(nèi)。 </p> <p> <br /> </p><p> 聚氨酯保溫管,就是用硬質(zhì)聚氨酯泡沫塑料做絕熱材料的保溫管道,其基本結(jié)構(gòu)由內(nèi)部工作管，中間硬質(zhì)聚氨酯泡沫塑料保溫層以及外防護(hù)管組成的。 </p> <p> 聚氨酯保溫管的分類分類方式很復(fù)雜,一般按照人們的習(xí)慣有一下幾種方式： </p> <p> 一、按照敷設(shè)方式可以分為:直埋聚氨酯保溫管、架空聚氨酯保溫管; </p> <p> 二、按照其輸送介質(zhì)的溫度可以分為:常溫聚氨酯保溫管、高溫聚氨酯保溫管、深冷聚氨酯保溫管； </p> <p> 三、按照外護(hù)層的不同可以分為:玻璃鋼外護(hù)層聚氨酯保溫管、高密度聚乙烯外護(hù)層聚氨酯保溫管、鋼外護(hù)層聚氨酯保濕管及其他外護(hù)層保溫管; </p> <p> 一般在工程施工中，聚氨酯保溫管**常用的分類方式還是以敷設(shè)方式來分，根據(jù)實(shí)際應(yīng)用環(huán)境來進(jìn)行分類，在施工中比較便利。 </p> <p> <br /> 聚氨酯保溫管使用聚乙烯外護(hù)管作為保護(hù)層，采用高密度聚乙烯材料制成，有良好機(jī)械強(qiáng)度和優(yōu)良的耐腐蝕性能。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣西埋地聚氨酯保溫管規(guī)格,聚氨酯保溫管"

聚氨酯保溫管的**外層是高密度聚乙烯保護(hù)層，預(yù)制成一定壁厚的黑色（黃色）塑料管材，在經(jīng)電暈工藝處理后備用。其作用一是保護(hù)聚氨酯保溫層免遭機(jī)械硬物破壞，二是防腐防水。保溫管應(yīng)用輸送在-50℃-140℃范圍內(nèi)的各種介質(zhì)的保溫保冷工程。它廣泛應(yīng)用于城市集中供熱、 </p> <p> 暖室、冷庫、煤礦、石油港口、化工等行業(yè)的保溫保冷工程。通常情況下，DN**N250采用無縫流體，DN250以上采用螺旋鋼管，也可根據(jù)工程需要采用用戶要求的各類鋼管。萬里管道的聚氨酯保溫管外套管采用高密度顆粒制成，具有很高的機(jī)械強(qiáng)度和優(yōu)良的耐腐蝕性能。它能保證管材在運(yùn)輸安裝及使用過程中不受外界因素的破壞。 </p> <p> <br /> 聚氨酯保溫管分類比較復(fù)雜，按照敷設(shè)方式可以分為：直埋聚氨酯保溫管道、架空聚氨酯保溫管道。廣西埋地聚氨酯保溫管規(guī)格</p><p style="text-indent:25px">聚氨酯保溫管的外護(hù)管接頭可采用PE熱縮帶或電熱熔套，保證密閉性及機(jī)械強(qiáng)度，且施工方便快捷。廣西埋地聚氨酯保溫管規(guī)格</p><p> 有時(shí)石油化工企業(yè)需要輸送一些劇毒、特殊物質(zhì)，采用普通鋼制材料的工作管是會(huì)受到腐蝕的，這時(shí)需要將聚氨酯保溫管的工作管更換為銅管。銅管又稱紫銅管，有色金屬管的一種，是壓制或拉制工藝生產(chǎn)的的無縫管。銅管具備了良好導(dǎo)電性，導(dǎo)熱性的特性，并且成為現(xiàn)代承包商在所有住宅商品房的自來水管道、供熱、制冷管道安裝的優(yōu)先。銅管抗腐蝕性能強(qiáng)，不易氧化，且與一些液態(tài)物質(zhì)不易起化學(xué)反應(yīng)，容易煒彎造型。直徑小的銅管常用于輸送有壓力的液體，萬里管道在一些特殊工程中，會(huì)使用銅管作為工作管，保護(hù)保溫管整體不受腐蝕。
