聚氨酯保溫管按照外護(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)層聚氨酯保溫管及鍍鋅鐵皮螺旋風(fēng)管外護(hù)層保溫管。一般在室內(nèi)非陽光直射條件下，大多數(shù)聚氨酯保溫管都能滿足需求，而在室外條件下，施工單位一般選用鋼外護(hù)層聚氨酯保溫管和鍍鋅鐵皮螺旋風(fēng)管外護(hù)層保溫管，在長期風(fēng)吹日曬條件下，不會(huì)受到腐蝕，抗疲勞性較強(qiáng)，質(zhì)量穩(wěn)定可靠。高密度聚乙烯外護(hù)管只能應(yīng)用于埋地敷設(shè)的聚氨酯保溫管中，因?yàn)樵谑艿疥柟庹丈湎?，聚乙烯?huì)出現(xiàn)開裂，影響保溫效果。 </p> <p> <br /> </p><p> 聚氨酯保溫管中的保溫層是用髙壓發(fā)泡機(jī)在鋼管于特制鋼模具之間形成的空腔中—次性注入硬質(zhì)聚氨酯泡沬塑料原液而成。即俗稱的“模具發(fā)泡工藝″。聚氨酯泡沬是否發(fā)滿,有任何質(zhì)量問題便于直接檢驗(yàn)。其作用一是防水,而是保溫,三是支撐熱網(wǎng)自重。當(dāng)輸送介質(zhì)溫度為:-50℃-120℃時(shí),選用硬質(zhì)聚氨基甲酸酯泡沬塑料做保溫層;當(dāng)輸送層。同時(shí)選用工作鋼管層時(shí),根據(jù)議計(jì)和客戶的要求一般選用無縫管螺旋焊管和直縫焊管。鋼管表面經(jīng)過先進(jìn)的拋丸除銹工藝處理后,鋼管除銹等級(jí)可達(dá)GB8923-1988標(biāo)準(zhǔn)中的Sa2級(jí),表面粗糙度可達(dá)GB6060.5-88標(biāo)準(zhǔn)中R=125微米。鋼管表面除污除銹后涂刷層氰凝防腐材料,其作用是防水,二是改善保溫層與鋼管之間的粘接表面,使它形成—個(gè)整體。

保溫管的安裝要求：首先按照設(shè)計(jì)圖紙的要求，驗(yàn)收管段質(zhì)量，仔細(xì)核對(duì)設(shè)計(jì)材料和各部位的幾何尺寸，充分考慮管段預(yù)留的位置和管道的吊裝措施，熱力管道上放空和放凈開孔均應(yīng)在地面時(shí)完成，管線在吊裝之前應(yīng)完成管道管托的焊接工作并完成管道及管托的油漆工作，管段預(yù)留焊口位置不刷油漆，吊管和布道安裝順序進(jìn)行，先安裝彎頭，后進(jìn)行直管安裝，待直管固定管托安裝完畢再進(jìn)行與彎管接口工作。
