If the direct-buried insulating pipe is damped due to improper care, the moisture in the insulating layer should be swept away by low temperature dehumidification method before blowing and running. Otherwise, the company produces high-temperature composite polyurethane direct-buried pipe, steel-lined steel direct-buried pipe, aluminium silicate tile, board, polyurethane tile and centrifugal glass wool, felt, etc. A variety of anti-corrosion and thermal insulation materials for your choice. For a long time, our products have been widely used in industrial and mining companies, petrochemical companies, urban central heating, pipeline network, residential areas and other areas all over the country, and have been highly praised by users.
款式: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。
Style: It is composed of steel pipe for delivery medium, anti-corrosion coat steel pipe and superfine glass wool filled between steel pipe and coat steel pipe.
特性:用钢管做钢管的维护层使产品具有强度高,不易损坏,承重量大的特性。
Characteristic: The steel pipe is used as the maintenance layer of the steel pipe, which makes the product have the characteristics of high strength, not easy to be damaged and heavy bearing capacity.
除外消费的直埋保温管,均设有渗漏报警线,一旦管道某处发作渗漏,经过报警线的传导,便可在专用检测仪表上显现出保温管道渗水,漏水的精确位置及渗漏水平的大小,以便通知检渗人员疾速处置漏水的管段,保证供热管网的平安运转。国内消费的保温管道目前末设渗漏报警线,有待补上这一空白。
All direct-buried insulating pipes except those consumed in China are equipped with leakage alarm lines. Once leakage occurs somewhere in the pipeline and is transmitted by the alarm lines, the leakage of insulating pipes, the exact location of the leakage and the size of the leakage level can be displayed on the special testing instruments, so as to inform the inspectors to quickly dispose of the leakage pipelines and ensure the level of the heating network. Safe operation. At present, leakage alarm line has been set up in domestic thermal insulation pipelines, which needs to be filled in.
总之,保温管不只具有传统地沟和架空敷设管道难以比较的技术,适用性能,而且还具有显著的社会效益和经济效益,也是供热的有力措施。采用直埋供热管道技术,标志着供热管道技术开展曾经进入了新的起点
In a word, thermal insulation pipe not only has advanced technology and applicability which is difficult to compare with traditional trench and overhead pipeline laying, but also has remarkable social and economic benefits. It is also a powerful measure of heating energy saving. The adoption of directly buried heating pipeline technology marks a new starting point for the development of heating pipeline technology in China.
可分为两大类：
It can be divided into two categories:
1,内滑动式：保温构造由工作钢管,硅酸铝,减阻层,微孔硅酸钙,隔热层,不锈钢紧固钢带,铝箔反射层,聚氨酯保温层,外套钢管,外防腐层组成。内滑动型保温钢管是由保送介质的钢管 复合硅酸盐或微孔硅酸钙 硬质聚氨酯泡沫塑料 外套钢管 玻璃钢壳防腐维护层构造构成。各种管件节点保温处置技术成熟,质量牢靠。
1. Inner sliding type: thermal insulation structure consists of working steel pipe, aluminium silicate, drag reduction layer, micro-porous calcium silicate, thermal insulation layer, stainless steel fastening strip, aluminium foil reflective layer, polyurethane thermal insulation layer, coated steel pipe, and external anti-corrosion layer. The inner sliding heat preservation steel pipe is composed of composite silicate or micro-porous calcium silicate rigid polyurethane foam plastic coat of steel pipe with anti-corrosion maintenance layer structure. All kinds of tubular joint heat preservation treatment technology is mature and the quality is reliable.
2,外滑动式：保温构造由工作钢管,玻璃棉保温隔热层,铝箔反射层,不锈钢紧固钢带,滑动导向支架,空气保温层,外护钢管,外防腐层组成。
2. External sliding type: thermal insulation structure consists of working steel pipe, glass wool thermal insulation layer, aluminum foil reflector layer, stainless steel fastening belt, sliding guide bracket, air thermal insulation layer, external steel pipe protection layer and external anti-corrosion layer.
主要由四局部组成。
It mainly consists 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。
(3) Maintenance case: high density polyethylene or glass fiber reinforced plastics.
（4）渗漏报警线：制造高温预制直埋保温管时,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 high-temperature prefabricated directly buried insulating pipe, an alarm line is embedded in the insulating layer near the steel pipe. Once leakage occurs somewhere in the pipeline and is transmitted by the alarm line, the alarm line can be used on the special detection instrument to show the exact position of leakage and the size of leakage level, so as to inform the maintenance personnel to deal with it quickly. Leakage section ensures safe operation of the heat network.
