</p> <p> 直埋式保溫管是由輸送介質(zhì)的鋼管，高密度聚乙烯外套管，以及鋼管和外套管之間的硬質(zhì)聚氨酯泡沫保溫層緊密結(jié)合而成。聚氨酯保溫管有保溫層一保護(hù)層，聚氨酯保溫板的保溫層是指它的內(nèi)側(cè)一次性注入保溫原液，如聚氨酯原液，我們有時(shí)候叫它“管中管發(fā)泡”。而保護(hù)層是指用聚乙烯材料在保溫管壁上預(yù)制一些在上面，其作用是避免它遭到其他金屬或者硬物的撞擊破壞。同時(shí)，這樣做了，保溫管還具有較好的防腐發(fā)法防水功能。

冷拔精密鋼管的特點(diǎn)：（1）外徑更小。（2）精度高可做小批量生。（3）冷拔成品精度高，表面質(zhì)量好。（4）鋼管橫面積更復(fù)雜。（5）鋼管性能更優(yōu)越，金屬比較密。 </p> <p> 熱軋精密鋼管后的區(qū)別 </p> <p>
