Product Details
 钢套钢蒸汽保温管,钢套钢地埋保温管
 
钢套钢保温管
一种是由输送介质的钢管、防腐外套钢管以及钢管与外套钢管之间填充的超细玻璃棉组合而成,也可采用石墨、硅钙瓦管壳及填充聚氨酯泡沫复合而成。钢套管(钢套钢)埋设技术是一种防水、防漏、抗渗、抗压和全封闭的埋设新技术,是直埋敷设技术在地下水位较高地区使用的一次较大突破。直埋管道的保护管的首要问题是严密防水的可靠性,此外要有良好的机械强度,钢套管由于强度高采用焊接连接,防水的密封性能可靠性十分高,另外,其耐高温性能也是其它外保护管所不能比拟的。在地下水位高的地区,为保证地下水不影响蒸汽直埋管道的正常运行,外保护层最好采用坚固、密闭的钢管外壳。
 
钢套钢保温管结构
一、保温结构防腐层+外护钢管+聚氨酯泡沫层+阻隔、反射层+无机硬质保温层+减阻层+工作钢管(Φ159以下的钢管加定心环保证内外管同心度)
二、结构机理 
1.防腐层:保护外钢管避免腐蚀物腐蚀钢管,延长钢管使用寿命。 
2.外护钢管: 保护保温层免受地下水侵蚀,支撑工作管并能承受一定的外部荷载,保证  工作管正常工作。 
3.聚氨酯泡沫层: 保证介质温度,保证外护管表面保持常温。 
4.阻隔、反射层: 保证有机泡沫材料不进入无机硬质耐高温层;反射耐高温层部分热量。
5.无机硬质保温层:耐高温,保证与有机保温层之间的界面温度,保证泡沫不被炭化。 
6.减阻层: 保证工作钢管热胀冷缩自由运动。
7.工作钢管:保证输送介质正常流动。     预制直埋保温管、聚氨酯保温管、高密度聚乙烯保温管、高密度聚乙烯预制直埋保温管、外套高密度聚乙烯保温管、塑套钢保温、钢套钢直埋保温、高温蒸汽直埋保温、钢管管件内外防腐保温、单层和双层熔结环氧粉末防腐(FBE)、双层聚乙烯(2PE)和三层聚乙烯防腐(3PE)、双层聚丙烯防腐(2PP)和三层聚丙烯(3PP)外涂敷工程,二三PE管道保温等产品金星公司均有生产,同时代理各大钢厂无缝钢管、螺旋管。

钢套钢蒸汽直埋保温管 
保温材料为优质超细玻璃棉管壳。超细玻璃棉管壳具有双层错缝包扎、接缝少,透气性好的优点,一旦保温层在施工过程中进水,完全可以通过逐步提高蒸气温度进行抽气排潮、逐步烘干。烘干后形状和保温性能保持良好。滚动支持结构设计合理,滚动摩擦力小,固定支座受力减小,其力学分析原理简单,管道稳定性、安全性得到较大提高。真空层彻底杜绝了空气层存在的热传导和热对流、极大地降低了热损失。与空气层结构相比,在同等保温厚度下可降低外壁温度8-13℃。抽真空装置彻底解决了外钢套管内壁容易被热湿空气腐蚀的难题,大大提高了直埋蒸汽管道的运行寿命。产品寿命提高到30年。抽真空装置彻底解决了空气层结构存在的每隔50-60m,必须设置一对排潮管的问题,极大地降低了外套管的破损率,使管道沿线更加美观。同时,降低了由于设置排潮管而增加的造价约50/m。钢外套管补口处一般不采用二块半瓦搭接焊的方式,而是在现场通过滑移钢外套管,逐根拼接的方式进行补口作业,与常规补口方式相比可减少40-50%的外套管口焊缝数量。焊缝数量的减少不仅缩短了缩短了安装工期、降低泄漏可能性,而且节省了大量焊接、超声波、X射线检验的费用
