除中國外消費的直埋保溫管,均設(shè)有滲漏報警線,一旦管道某處發(fā)作滲漏,經(jīng)過報警線的傳導(dǎo),便可在專用檢測儀表上顯現(xiàn)出保溫管道滲水,漏水的精確位置及滲漏水平的大小,以便通知檢滲人員疾速處置漏水的管段,保證供熱管網(wǎng)的平安運轉(zhuǎn)。國內(nèi)消費的保溫管道目前末設(shè)滲漏報警線,有待補上這一空白。
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.
總之,保溫管不只具有傳統(tǒng)地溝和架空敷設(shè)管道難以比較的先進技術(shù),適用性能,而且還具有顯著的社會效益和經(jīng)濟效益,也是供熱節(jié)能的有力措施。采用直埋供熱管道技術(shù),標志著中國供熱管道技術(shù)開展曾經(jīng)進入了新的起點
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.
可分為兩大類：
It can be divided into two categories:
1,內(nèi)滑動式：保溫構(gòu)造由工作鋼管,硅酸鋁,減阻層,微孔硅酸鈣,隔熱層,不銹鋼緊固鋼帶,鋁箔反射層,聚氨酯保溫層,外套鋼管,外防腐層組成。內(nèi)滑動型保溫鋼管是由保送介質(zhì)的鋼管 復(fù)合硅酸鹽或微孔硅酸鈣 硬質(zhì)聚氨酯泡沫塑料 外套鋼管 玻璃鋼殼防腐維護層構(gòu)造構(gòu)成。各種管件節(jié)點保溫處置技術(shù)成熟,質(zhì)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,外滑動式：保溫構(gòu)造由工作鋼管,玻璃棉保溫隔熱層,鋁箔反射層,不銹鋼緊固鋼帶,滑動導(dǎo)向支架,空氣保溫層,外護鋼管,外防腐層組成。
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.
主要由四局部組成。
It mainly consists of four parts.
（1）工作鋼管：依據(jù)保送介質(zhì)的技術(shù)請求分別采用有縫鋼管,無縫鋼管,雙面埋弧螺旋焊接鋼管。
(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）保溫層：采用硬質(zhì)聚氨酯泡沫塑料。
(2) Insulation layer: rigid polyurethane foam.
（3）維護殼：采用高密度聚乙烯或玻璃鋼。
(3) Maintenance case: high density polyethylene or glass fiber reinforced plastics.
（4）滲漏報警線：制造高溫預(yù)制直埋保溫管時,在靠近鋼管的保溫層中,埋設(shè)有報警線,一旦管道某處發(fā)作滲漏,經(jīng)過警報線的傳導(dǎo),便可在專用檢測儀表上報警并顯現(xiàn)出漏水的精確位置和滲漏水平的大小,以便通知檢修人員疾速處置漏水的管段,保證熱網(wǎng)平安運轉(zhuǎn)。
(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.
