黑夾克直埋保溫鋼管廠家聚氨酯直埋保溫管是一種保溫性能好，加平安牢靠，工程造價低的直埋預(yù)制保溫管。
The polyurethane direct-buried insulating pipe manufacturer of black jacket direct-buried insulating pipe is a kind of direct-buried prefabricated insulating pipe with good thermal insulation performance, safety and reliability, and low cost.
直埋保溫管不只具有傳統(tǒng)地溝和架空敷設(shè)管道難以比較的技術(shù)、適用性能，而且還具有顯著的社會效益和經(jīng)濟(jì)效益，也是供熱的有力措施。
Direct buried insulating 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.

(3)聚氨酯保溫鋼管維護(hù)殼：采用高密度聚乙烯或玻璃鋼。
(3) Polyurethane insulating steel pipe maintenance shell: using high density polyethylene or FRP.
(4)聚氨酯保溫鋼管滲漏報警線：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(yùn)轉(zhuǎn)。
(4) Leakage alarm line for polyurethane insulating steel pipes: When manufacturing high temperature prefabricated directly buried insulating pipes, an alarm line is embedded in the insulating layer near the steel pipes. 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 maintenance personnel to quickly dispose of the leaky pipe section and ensure that The heat supply network operates safely.
聚氨酯保溫鋼管保溫層：維護(hù)外鋼管防止腐蝕物腐蝕鋼管，延長鋼管運(yùn)用壽命;外護(hù)鋼管:維護(hù)保溫層免受公開水腐蝕，支撐工作管并能接受一定的外部荷載;聚氨酯泡沫層:保證介質(zhì)溫度，保證外護(hù)管外表堅持常溫;阻隔、反射層:保證有機(jī)泡沫資料不進(jìn)入無機(jī)硬質(zhì)耐高溫層；反射耐高溫層局部熱。聚氨酯保溫管在構(gòu)造上具有下列特性：
Polyurethane insulation steel pipe insulation: maintenance of external steel pipe to prevent corrosion corrosion steel pipe, prolong the service life of steel pipe; external protection steel pipe: maintain insulation layer from open water corrosion, support the work pipe and can accept certain external load; polyurethane foam layer: ensure the medium temperature, ensure the external tube surface adhere to normal temperature; barrier, reflective layer: ensure that the organic foam data does not enter the inorganic hard and high resistance. Temperature layer; Reflects local heat of high temperature resistant layer. Polyurethane insulating pipes have the following structural characteristics:
1、采用固定在內(nèi)工作鋼管上的活動支架和外套管內(nèi)壁摩擦，保溫資料跟隨工作鋼管一同活動，不會呈現(xiàn)保溫資料的機(jī)械磨損、粉化。
1. The movable bracket fixed on the inner working steel pipe and the inner wall friction of the outer sleeve are adopted. The thermal insulation data will follow the working steel pipe and will not show the mechanical wear and pulverization of the thermal insulation data.
2、外套鋼管強(qiáng)度高、密封性能好，可有效地防水、抗?jié)B。
2. The coated steel pipe has high strength and good sealing performance, which can effectively waterproof and impermeable.
3、外套鋼管的外壁采用防腐處置，使外套鋼管的防腐層壽命在20年以上。
3. The outer wall of the coated steel pipe is treated with high-quality anticorrosive treatment, so that the life of the anticorrosive layer of the coated steel pipe is longer than 20 years.
4、工作鋼管的保溫層選用保溫資料，保溫效果好。
4. The insulation layer of the working steel pipe is made of high-quality insulation materials, and the insulation effect is good.
5、工作鋼管保溫層與外套鋼管之間留有10~20mm左右的間隙，既可直到進(jìn)一步保溫的作用。又是直埋管道極為通暢的排潮通道，使排潮管真正起到及時排潮的作用，同時起到信號管的作用；或?qū)⑵涑槌傻驼婵眨筛行У乇夭⒔档屯馓坠軆?nèi)壁腐蝕聚氨酯保溫鋼管工作負(fù)管滾動支架采用特種低熱資料制成，與鋼材的摩擦系數(shù)為0.1左右，管道運(yùn)轉(zhuǎn)時摩擦阻力較小。工作鋼管的固定支架，滾動支架與工作鋼管的銜接采用特別設(shè)計，可有效地避免管道熱橋的產(chǎn)生。
5. There is a gap of about 10-20 mm between the insulation layer of the working steel pipe and the outer steel pipe, which can be used for further insulation. It is also a very smooth channel for the direct buried pipeline to drain the tide in time and signal tube at the same time; or it can be pumped into a low vacuum, which can more effectively insulate and reduce the corrosion of the inner wall of the outer sleeve, polyurethane thermal insulation pipe working negative tube rolling support is made of special low-heat data, the friction coefficient with steel is about 0.1, and the friction resistance when the pipeline is running. The force is small. Fixed bracket of working steel pipe, rolling bracket and connection of working steel pipe are specially designed, which can effectively avoid the generation of pipeline hot bridge.
