聚氨酯保溫管的高密度聚乙烯外護(hù)管分為“一步法”和“兩步法”制作工藝，聚氨酯硬質(zhì)泡沫保溫層與外部保溫用高密度聚乙烯外護(hù)管（夾克管）一次成型的工藝，我們稱這為“一步法”，制作流程：鋼管除銹——鋼管防腐——聚氨酯發(fā)泡——成形——成品監(jiān)測(cè)——入庫(kù)。先生產(chǎn)出高密度聚乙烯外護(hù)層，然后在聚乙烯外護(hù)層與鋼管之間的空隙再澆筑聚氨酯硬質(zhì)泡沫塑料保溫層的制作工藝就是我們常說的“兩步法”。一步法適合生產(chǎn)管道在5000米甚至是10000米以上這種大批量而且單一品種的管道發(fā)泡，效率非常高。兩步法適合生產(chǎn)管道在幾百、數(shù)千米左右的訂單。 </p> <p> <br /> </p><p> 聚氨酯保溫管生產(chǎn)后需要進(jìn)行驗(yàn)收，驗(yàn)收合格后方可交付給工程使用。進(jìn)場(chǎng)檢查：聚氨酯保溫兼防水材料具備兩重性能，材料進(jìn)場(chǎng)以后，必須對(duì)原材料進(jìn)行復(fù)試，復(fù)試主要內(nèi)容為材料的密度、壓縮性能、尺寸穩(wěn)定性、不透水性等；防水性能檢查：采用蓄水或雨淋的辦法檢查其防水效果，不得出現(xiàn)積水和滲漏水現(xiàn)象；噴涂厚度檢查：采用鋼針插入和量測(cè)的方法檢查厚度。經(jīng)過驗(yàn)收檢查合格后，萬(wàn)里管道生產(chǎn)的聚氨酯保溫管才可以出廠，保證工程施工質(zhì)量合格。

聚氨酯保溫管是分三層的結(jié)構(gòu),這種管材有一層外保護(hù)層、還有一層保溫層和防滲漏層外保護(hù)層材料是玻璃鋼材料或者是聚乙烯材料,也可能是其他材料。這種管材的敷設(shè)方式有直埋的方式、架空的方式、以及少量采取地溝方式這樣的三種敷設(shè)形式。聚氨酯保溫管的應(yīng)用十分普遍,這種管材目前被普遍應(yīng)用在石油領(lǐng)域、化工領(lǐng)域、城區(qū)熱網(wǎng)等工程之中,適用的保溫范圍在-50℃—120℃的溫度,逐漸擴(kuò)大,已經(jīng)達(dá)到了-70°—140°范圍,這種管材主要用在管道的保溫隔熱、容器內(nèi)熱介質(zhì)物料的保溫隔熱等。 </p> <p> <br /> 聚氨酯保溫管的使用壽命除了生產(chǎn)廠家的質(zhì)量好壞外，施工質(zhì)量的差異也占了相當(dāng)大的比重。四川供熱聚氨酯保溫管推薦咨詢</p><p style="text-indent:25px">聚氨酯保溫管，全稱為高密度聚乙烯塑料外護(hù)聚氨酯泡沫預(yù)制直埋保溫管。四川供熱聚氨酯保溫管推薦咨詢</p><p> 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，使保溫管的運(yùn)行安全可靠。PE熱縮帶是由輻射交聯(lián)聚烯烴基材和特種密封熱熔膠復(fù)合而成，特種密封熱熔膠與聚烯烴基材、鋼管表面及固體環(huán)氧涂層可形成良好的粘接。WK-WSS聚乙烯熱縮帶在加熱安裝時(shí)，基材在徑向收縮的同時(shí)，內(nèi)部復(fù)合膠層熔化，緊緊地包覆在補(bǔ)口處，與基材一起在管道外形成了一個(gè)牢固的防腐體，具有優(yōu)異的耐磨損、耐腐蝕、抗沖擊及良好的抗紫外線和光老化性能。使用PE熱縮帶的萬(wàn)里管道聚氨酯保溫管，便于規(guī)模化生產(chǎn)，施工也方便很多。
