工作含有鐵的聚氨酯保溫管一般分為三層。首層為工作鋼管層，四川聚氨酯保溫管批發(fā)廠家，根據(jù)設(shè)計和客戶的要求一般選用無縫鋼管、螺旋鋼管和直縫鋼管。第二層為氨酯保溫層。用高壓發(fā)泡機在鋼管與外護層之間形成的空腔中一次性注入硬質(zhì)聚氨酯泡沫塑料原液而成。第三層為密度聚乙烯保護層。其作用是保護聚氨酯保溫層,防腐、防水。如今,聚氨酯保溫管的應(yīng)用非常普遍,一些廠家在生產(chǎn)聚氦酯保溫管的時候在節(jié)能方面做了很大的改進。以目前情況而言,聚氨酯保溫管的優(yōu)越性是任何保溫管道都難以比擬的。它保溫性能很好,節(jié)省了能源,占地面積少，四川聚氨酯保溫管批發(fā)廠家、工程造價低，四川聚氨酯保溫管批發(fā)廠家、施工周期短等優(yōu)點博得了廣大客戶的認可。

聚氨酯保溫管的保溫效果是非常好的。當直埋式聚氨酯保溫管未敷土,大氣溫度為20℃時,外套鋼管外壁溫度*為31""℃,散熱損失為202W/m?？梢娋郯滨ケ毓艿谋匦Ч窍喈敽玫?當直埋式聚氨酯保溫管道敷設(shè)于土壤中,由于土壤也具有一定的保溫作用,使道的散熱損失更加少,外套管外壁的溫度也相應(yīng)有所提高。綜上所述，當管頂敷土深度大于0.8m,外套鋼管外表面溫度小于60℃時,直埋管道對周圍其他管道或地表植被幾乎沒有影響。萬里管道生產(chǎn)的聚氨酯保溫管保溫效果優(yōu)良，熱損極低，是城鎮(zhèn)供熱管道的比較好選擇。
