鋼套鋼蒸汽保溫管一種是由保送介質(zhì)的鋼管、防腐外套鋼管以及鋼管與外套鋼管之間填充的超細玻璃棉組合而成,也可采用石墨、硅鈣瓦管殼及填充聚氨酯泡沫復合而成。鋼套管（鋼套鋼）埋設技術(shù)是一種防水、防漏、抗?jié)B、抗壓和全封鎖的埋設新技術(shù)，是直埋敷設技術(shù)在公開水位較高地域運用的一次較大打破。
A steam insulated pipe with steel sleeves is made up of a super fine glass wool which is filled with a steel pipe, an anticorrosive coat tube, and a steel tube filled with steel tube and outer steel pipe. It can also be made of graphite, calcium silicate tile and polyurethane foam. Steel sleeve (steel sleeve) embedding technology is a new embedding technology of waterproof, leak-proof, impermeability, compression and full blockade. It is a great break in the application of direct embedding technology in areas with high open water level.
直埋管道的維護管的首要問題是緊密防水的牢靠性，此外要有良好的機械強度，鋼套管由于強度高采用焊接銜接，防水的密封性能牢靠性非常高，另外，其耐高溫性能也是其它外維護管所不能比較的。
The primary problem for the maintenance pipe of directly buried pipeline is the reliability of tight waterproof. Besides, it should have good mechanical strength. Because of the high strength of steel sleeve, welding connection is adopted, the reliability of waterproof sealing performance is very high. In addition, its high temperature resistance performance can not be compared with other external maintenance pipes.
