黑夾克聚氨酯保溫鋼管用于集中供熱、供冷和熱油的輸送及分配的保溫管的鋼管和聚乙烯外護管，二者用聚氨酯泡沫絕熱材料緊密地結合為一體。管徑范圍是Φ90～Φ1240，保溫管全稱叫高密度聚乙烯聚氨酯硬泡沫發(fā)泡保溫管，它的作用是保護工作管內部流體的溫度，防止與外界發(fā)生熱傳遞，導致流體溫度的流失。

    黑夾克聚氨酯保溫鋼管保溫材料用于各類冷水、冷氣、冷油管線圓形、異形及任何形體的管道保溫。 防止結露：聚乙烯發(fā)泡管材料為閉孔結構，它是靠閉孔內的氣體絕熱而非聚乙烯材料實現(xiàn)絕熱。其具有優(yōu)異的抗水汽滲透能力。所形成內置的隔汽屏障，即是保溫層又是隔汽層，不需另設隔汽層。濕阻因子ц數(shù)值遠遠大于其它保溫材料。能有效地避免結露現(xiàn)象發(fā)生。

該技術是把絕熱層和防腐層同時包覆在鋼管道外表面上，從而形成管線的保溫防腐層，屬國內*。與其他方法相比，具有連續(xù)作業(yè)、生產(chǎn)效率高、成本低、節(jié)約能源、無污染環(huán)境等突出優(yōu)點，1985年獲國家科技進步二等獎，幾經(jīng)科技更新，達到先進水平。

        用一步法成型方法建成的鋼管道絕熱防腐生產(chǎn)線自動化程度高，絕熱防腐層的質量*符合國家標準。

        該技術自83年研制成功以來，經(jīng)近二十年的改進提高，目前已形成作業(yè)管線范圍達φ48mm～φ1000mm以上。絕熱防腐層鋼管主要用于原油輸送管道、直埋式供熱管道和制冷系統(tǒng)管道的絕熱防腐，應用前景十分廣泛，率*。可應用于集中供熱單位、遠距離輸油、供水、供氣等工程。

        鋼管道防腐保溫泡沫夾克成型技術是八十年代初，由原來石油部基建局組織專家赴加拿大考察后，在國內油田推廣的新技術，并在國外 “ 二步法 ” 成型工藝的基礎上，由勝利油田油建工藝技術研究所于 1983 年推出“一步法”成型技術，即鋼管道泡沫防腐保溫成型技術與外部保溫用夾克層一次成型，我們稱這為“一步法”作業(yè)。這一工藝技術的成功，不但提高了作業(yè)效率，也大大節(jié)省了材料，降低了成本，方便了施工，很快這一技術在全國油田得到了推廣，并獲得了山東省科技成果， 1985 年獲得國家發(fā)明，直至目前，國內沒有“一步法”技術問世。
