在中，小口徑的熱輸原油或供暖管道上，聚氨酯發泡保溫鋼管的焊接知識為了減少管道向土壤散熱，碳鋼防腐鋼管在管道外部加上保溫復合層。常用的保溫材料是硬質聚氨脂泡沫塑料，適用溫度為－185～120℃。這種材料質地松軟，聚氨酯發泡保溫鋼管-聚氨酯保溫鋼管-直埋聚氨酯保溫鋼管-聚氨酯保溫鋼管廠家-滄州世鋒管道制造有限公司為提高其強度，在隔熱層外面加敷一層高密度聚乙烯層，聚氨酯發泡保溫鋼管的焊接知識形成復合材料結構，碳鋼防腐鋼管以到達去除油，碳鋼防腐鋼管提高保溫管的粘接性能。保溫層材料為密度60kg/m3至80kg/m3的硬質聚氨酯泡沫，充分添滿鋼管與套管之間的間隙，并具有一定的粘接強度，使鋼管，外套管及保溫層三者之間形成一個牢固的整體。聚氨酯泡沫具有良好的機械性能和絕熱性能，通常情況下可耐溫120℃,通過改性或與其它隔熱材料組合可耐溫180℃。應用溶劑，乳劑清洗鋼材外表，以到達去除油，油脂，塵土，光滑劑和相似的有機物，但它不能去除鋼材外表的銹，氧化皮，焊藥等，因而在防腐出產中只作為輔佐伎倆。
