          鋼套鋼保溫管由輸送介質的,工作鋼管、泡沫保溫層、聚乙烯塑料外護管,通過設備依次向外結合而成。聚氨酯保溫層其作用一是防水,二是保溫,架空預制鋼套鋼蒸汽保溫管備注,三是支撐熱網自重。當輸送介質溫度為:-50℃—120℃時,鋼套鋼蒸汽保溫管,選用硬質聚氨基脲酸酯泡沫塑料做保溫層。
          The steel sleeve steel insulation pipe is made up of conveying medium, working steel pipe, foam insulation layer and polyethylene plastic external protection pipe, and is sequentially integrated outwardly through the equipment. Polyurethane insulation layer has the functions of waterproof and thermal insulation. It can support the self weight of heat supply network. When the conveying medium temperature is -50 - 120 - C, the steel sleeve steel steam insulation pipe is made of rigid polyurethane urea foam as insulation layer.
          塑料管材,其作用一是保護聚氨酯保溫層免遭機械硬物破壞,二是防腐防水。
          Plastic pipe, its role is to protect the polyurethane insulation layer from mechanical damage, the other is anti-corrosion and waterproof.

          鋼套鋼直埋保溫管是一種保溫性能好,加可靠,工程造價低的直埋預制保溫管。有效的了城鎮集中供熱中130℃-600℃高溫輸熱用預制直埋保溫管的保溫、滑動潤滑和裸露管端的防水問題。鋼套鋼保溫管不僅具有傳統地溝和架空敷設管道難以比擬的技術、實用性能,而且還具有顯著的社會效益和經濟效益,也是供熱的有力措施。
          The steel sleeve steel directly buried insulation pipe is a kind of directly buried prefabricated insulation pipe with good thermal insulation performance, safety and reliability, and low engineering cost. It can effectively solve the problems of heat preservation, sliding lubrication and waterproof of exposed pipe end for 130 ℃ - 600 ℃ high temperature heat transfer in urban central heating. Steel insulated steel pipe not only has the advanced technology and practical performance that traditional trench and overhead laying pipeline can't match, but also has remarkable social and economic benefits, which is also a powerful measure of heating and energy saving.
          鋼套鋼保溫管由工作鋼管、保溫層、滾動導向管托、外套管(鋼管)、防腐層組成,保溫材料捆扎在工作鋼管上,依靠滾動導向管托在外套管內整體式熱膨脹移動,故不損壞保溫層,固定支架為內置式固定支架,無須原先“三通式固定支架”的龐大的鋼筋混凝土支墩,是理想的蒸汽管敷設方式。經多年使用實踐中和有關檢測檢測使用壽命可達三十年以上。
          The steel insulated steel pipe is composed of working steel pipe, insulation layer, rolling guide pipe bracket, outer sleeve (steel pipe) and anti-corrosion layer. The thermal insulation material is bound on the working steel pipe and moves by integral thermal expansion in the outer sleeve supported by the rolling guide pipe. Therefore, the insulation layer is not damaged. The fixed support is built-in fixed support instead of the huge reinforced concrete buttress of the original "three-way fixed support" It is an ideal way to lay steam pipe. After many years of practice and relevant testing centers, the service life can reach more than 30 years.
          保溫層保溫材料選用憎水型復合硅酸鹽管殼或XN-3硅酸鋁(防潮陶瓷制品)保溫管殼,亦可應客戶要求選用其它材質的保溫材料。保溫材料錯面雙層錯縫捆扎在工作鋼管上連成一體,減少了熱損失,與鋼套管不發生面摩擦,延長了保溫層的使用壽命,其厚度隨介質溫度而定。
          Hydrophobic composite silicate pipe shell or xn-3 aluminum silicate (moisture-proof ceramic products) insulation pipe shell shall be selected as thermal insulation material for thermal insulation layer, and other materials can also be selected according to customer requirements. The thermal insulation material is bound on the working steel pipe to reduce the heat loss and avoid friction with the steel sleeve, thus prolonging the service life of the insulation layer. The thickness of the insulation layer depends on the temperature of the medium.
