吊裝布管是聚氨酯保溫管進(jìn)入工程施工現(xiàn)場(chǎng)的首步，也是重要的一步。萬(wàn)里管道施工規(guī)范要求吊裝布管時(shí)應(yīng)采用吊環(huán)吊裝，不得采用卡扣直接吊芯管或套管管口，以免變形。吊裝時(shí)應(yīng)采用布帶或其他不損傷外防腐得設(shè)備吊裝，嚴(yán)禁用鋼絲繩直接捆綁吊裝，以免損傷外防腐層。聚氨酯保溫管可單根吊入溝內(nèi)安裝，也可2根或多根組焊完后吊裝。當(dāng)組焊管段較長(zhǎng)時(shí)，宜用兩臺(tái)或多臺(tái)吊車抬管下管，吊點(diǎn)的位置按平衡條件選定。應(yīng)用柔性吊帶起吊，并應(yīng)穩(wěn)起穩(wěn)效，嚴(yán)禁將管道直接推入溝內(nèi)。規(guī)范的吊裝能夠避免不必要的損傷，湖南預(yù)制冷熱水聚氨酯保溫管生產(chǎn)廠家，萬(wàn)里管道長(zhǎng)期遵守施工規(guī)范，湖南預(yù)制冷熱水聚氨酯保溫管生產(chǎn)廠家，質(zhì)量安全可靠。

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(lái)進(jìn)行輸送。PVC管不能承受太大的壓力但是因?yàn)楣鼙诠饣?，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(guò)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(qiáng)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(shè)時(shí)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>

聚氨酯保溫管是各大工業(yè)部門不可或缺的保溫材料，聚氨酯保溫管以其優(yōu)良的性能及特點(diǎn)而備受人們的歡迎?，F(xiàn)在，國(guó)內(nèi)許多的專業(yè)設(shè)計(jì)院和生產(chǎn)廠家正在利用先進(jìn)的技術(shù)不斷的更新保溫管的外觀、性能，當(dāng)然，市場(chǎng)的競(jìng)爭(zhēng)是不可避免的。市場(chǎng)的優(yōu)勝劣汰機(jī)制下，一些不**廠家及其生產(chǎn)的不合格產(chǎn)品被下架。萬(wàn)里管道憑借其完備的生產(chǎn)體系，精細(xì)化的加工工藝，在眾多廠家中脫穎而出，產(chǎn)品質(zhì)量安全可靠，使用壽命長(zhǎng)久穩(wěn)定。聚氨酯保溫管是應(yīng)用**為普遍的保溫管。 </p> <p> <br /> </p><p> 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(shuō)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。
