          1、內鋼管
          1. Inner steel pipe
          2、富鋅底漆
          2. Zinc rich primer
          3、滑動導向支架
          3. Slide guide bracket
          4、耐高溫玻璃棉
          4. High temperature resistant glass wool
          5、鋁箔反射層
          5. Aluminum foil reflector
          6、空氣保溫層
          6. Air insulation layer
          7、外套鋼管
          7. Outer steel pipe
          8、外套鋼管防腐層

          直埋式高溫蒸汽用預制保溫管是地下直埋中的一種管道,采用沒有混凝土結構的情況下也可以進行地下直埋的方式,即工作鋼管的熱膨脹在外管內進行,從而降低了材料成本,縮短了施工日期,并保障了供熱管道的性,可以在不同溫度環境下更的廣泛應用,尤其適用于高溫蒸汽管道項目。使用溫度可達150℃-450℃。

          The prefabricated insulation pipe for directly buried high-temperature steam is a kind of pipe directly buried underground. It can also be directly buried without concrete structure, that is, the thermal expansion of the working steel pipe is carried out in the outer pipe, so as to reduce the material cost, shorten the construction date, and ensure the safety of the heat supply pipeline. It can be widely used in different temperature environments more safely It is especially suitable for high temperature steam pipeline project. The operating temperature can reach 150 ℃ - 450 ℃.
          內鋼管選用二度無機富鋅底漆(耐溫≥400℃)防腐涂層,管道端口選用聚乙烯薄膜或三層PE冷纏帶密封,防止安裝前進入潮氣或施工中進入水。保溫材料多層錯縫包扎,有效減少了熱損失,同時控制外套表面措施,防止了冷橋的產生,從而使外套防腐層的溫度控制得到了保證。用保溫材料包扎多層鋁箔反射層,有效減少了熱損失,使蒸汽管道更加經濟合理。
          The inner steel pipe shall be coated with two-layer inorganic zinc rich primer (temperature resistance ≥ 400 ℃), and the pipe end shall be sealed with polyethylene film or three-layer PE cold wrapping tape to prevent moisture entering before installation or water entering during construction. The heat loss is effectively reduced by multi-layer staggered seam wrapping of thermal insulation material. At the same time, the measures to control the surface of the jacket prevent the generation of cold bridge, thus ensuring the temperature control of the coating. The multi-layer aluminum foil reflective layer wrapped with thermal insulation material can effectively reduce the heat loss and make the steam pipeline more economical and reasonable.
          外套鋼管防腐采用防腐涂層與陰極保護聯合防護,使防腐壽命可大大增加。疏水系統采用全封閉的形式,布置靈活,結構合理,可靠。鋼套管上的排潮管既能及時排出潮濕氣體,又可作為日常運行的報警信號管。管道的熱補償采用波紋管補償器,并將其裝設在套管內,做成直埋形式,無須設置觀察井,施工操作方便、工期短。
          The anticorrosive coating and cathodic protection are combined to protect the outer steel pipe from corrosion, which can greatly increase the anticorrosion life. The drainage system adopts fully enclosed form, flexible layout, reasonable structure, safety and reliability. The moisture discharge pipe on the steel sleeve can not only discharge the wet gas in time, but also be used as the alarm signal pipe for daily operation. High quality bellows compensator is used for thermal compensation of pipeline, which is installed in casing and directly buried without observation well.
