钢套钢保温钢管全封闭的埋设技术的使用

来源:http://www.rrhsf.com 日期:2019-05-27 发布人:admin
钢套管(钢套钢)埋设技术是一种防水、防漏、抗渗、抗压和全封锁的埋设新技术,是直埋敷设技术在公开水位较高地域运用的一次较大打破。它是由保送介质的钢管、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。
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. It is made up of super fine glass wool which is filled with steel pipes, anticorrosive steel tubes and steel pipes filled with steel pipes and outer steel pipes. It can also be made of graphite, calcium silicate tiles and polyurethane foam.
一种是由保送介质的钢管、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、抗压和全封锁的埋设新技术,是直埋敷设技术在公开水位较高地域运用的一次较大打破。直埋管道的维护管的首要问题是紧密防水的牢靠性,此外要有良好的机械强度,钢套管由于强度高采用焊接衔接,防水的密封性能牢靠性非常高,另外,其耐高温性能也是其它外维护管所不能比较的。在公开水位高的地域,为保证公开水不影响蒸汽直埋管道的正常运转,外维护层采用巩固、密闭的钢管外壳。
One is made from the super fine glass wool which is filled with the steel pipe, the anticorrosive coat pipe and the filled steel tube between the steel pipe and the outer steel pipe. It can also be made of graphite, calcium silicate tile shell 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. 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. In the area with high open water level, in order to ensure that the open water does not affect the normal operation of the directly buried steam pipeline, the external maintenance layer adopts a consolidated and sealed steel tube shell.
聚氨酯保温钢管厂家
预制聚氨酯直埋保温管主要由四局部组成。
The prefabricated polyurethane direct-buried insulation pipe is mainly composed of four parts.
1工作钢管:依据保送介质的技术请求分别采用有缝钢管、无缝钢管、双面埋弧螺旋焊接钢管。
1. Working steel pipe: According to the technical requirements of delivery medium, seamless steel pipe, double-sided submerged arc spiral welded steel pipe are used respectively.
2保温层:采用硬质聚氨酯泡沫塑料。
2. Insulation layer: rigid polyurethane foam.
3维护壳:采用高密度聚乙烯或玻璃钢。
Maintenance Shell: High Density Polyethylene or Glass Fiber Reinforced Plastic.
4渗漏报警线:制造预制聚氨酯直埋保温管时,在靠近钢管的保温层中,埋设有报警线,一旦管道某处发作渗漏,经过警报线的传导,便可在专用检测仪表上报警并显现出漏水的精确位置和渗漏水平的大小,以便通知检修人员疾速处置漏水的管段,保证热网平安运转。
4. Leakage alarm line: When manufacturing prefabricated polyurethane direct-buried insulation pipe, an alarm line is embedded in the insulation layer near the steel pipe. Once leakage occurs somewhere in the pipeline and is transmitted by the alarm line, it can alarm on the special detection instrument and show the exact position and level of leakage, so as to inform the inspectors to quickly dispose of the leakage pipe section and ensure the safe operation of the heat network. 。
相信看了本文的聚氨酯保温钢管厂家http://www.rrhsf.com介绍后,对这方面也会有自己的一番认识,以后针对的等问题也能很好的解决。
It is believed that after reading the introduction of http://www.rrhsf.com, the polyurethane insulation steel pipe manufacturer in this paper, they will have their own understanding of this aspect, and other problems can be solved well in the future.
