聚氨酯保溫管的工作溫度是由一定范圍的。聚氨酯保溫管應能在135℃下連續(xù)工作至少30年,并提供相應老化試驗報告,聚氨酯保溫層要能耐150℃的瞬時峰值而無碳化和變形,并提供國家認可的檢測部門出具的預制型式檢測報告。保溫管道應具有變形性能,在30年的使用壽命內(nèi),任一點的變形量不能超過20mm。當變形量大于一定程度時，會產(chǎn)生裂痕或開裂，影響保溫性能。萬里管道建議，聚氨酯保溫管在室外架設時，外護管不要選用高密度聚乙烯管，在陽光直射下聚乙烯會產(chǎn)生形變，影響保溫性能。

輸送介質(zhì)非熱水的情況下，聚氨酯保溫管可以使用PVC管作為工作管來進行輸送。PVC管不能承受太大的壓力但是因為管壁光滑，流體阻力很小，疏水能力比同等管徑的鑄鐵管提高20%。經(jīng)過大量工程研究發(fā)現(xiàn)： </p> <p> 1、PVC管具有較好的抗拉、抗壓強度：但其柔性不如其他塑料管。 </p> <p> 2、管道耐腐蝕性、耐藥品性優(yōu)良：PVC-U管材具有優(yōu)異的耐酸，耐堿，耐腐蝕，不受潮濕水份和土壤酸堿度的影響，管道鋪設時不需任何防腐處理。 </p> <p> 3、PVC管具有良好的水密性：PVC-U管材的安裝，不論采用粘接還是橡膠圈連接，均具有良好的水密性。 </p> <p> 4、PVC管可作生活用水供水管,但不宜作為直接飲用水供水管。 </p> <p> <br />

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、按照外護層的不同可以分為:玻璃鋼外護層聚氨酯保溫管、高密度聚乙烯外護層聚氨酯保溫管、鋼外護層聚氨酯保濕管及其他外護層保溫管; </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方式來分，根據(jù)實際應用環(huán)境來進行分類，在施工中比較便利。
