Polyurethane direct buried insulation pipe is an ideal product for central heating because of its good quality and low price. This phenomenon generally occurs in spring and summer or at noon construction, because the temperature is too jumping. But use cold water or dark night to cool naturally outside to prevent direct sunlight. Have the level of sales personnel, customers have inquiry can call consultation or factory investigation.

　　保溫管聚氨酯直接埋地保溫管，又稱“管中管”，由“兩步法”組成，由高密度聚乙烯外養(yǎng)護層、聚氨酯硬質泡沫塑料管和鋼管組成。

　　The insulating pipe directly buried heat insulation pipe, also known as "tube in tube", consists of two steps, consisting of high density polyethylene curing layer, polyurethane rigid foam pipe and steel pipe.

　　保溫材料為60kg/m380kg/m3的硬質聚氨酯泡沫塑料，填充鋼管與套管之間的空間，具有一定的粘結強度，使鋼管、外套管與保溫材料形成一個整體。保溫鋼管泡沫具有優(yōu)良的機械保溫和保溫功能，通常120℃可以改性或與其他保溫材料結合使用可以承受180℃。保溫材料為60kg/m380kg/m3的硬質聚氨酯泡沫塑料，填充鋼管與套管之間的空間，具有一定的粘結強度，使鋼管、外套管與保溫材料形成一個整體。保溫鋼管泡沫具有優(yōu)良的機械保溫和保溫功能，通常120℃可以修改或與其他保溫數據相結合的保溫鋼管

　　The thermal insulation material is 60kg/m3 to 80kg/m3 rigid polyurethane foam, the space between the filled steel pipe and the casing has certain bond strength, so that the steel tube, outer tube and insulation material form a whole. The thermal insulation steel pipe foam has excellent mechanical insulation and thermal insulation function. It can be modified at 120 C or combined with other insulation materials, and it can withstand 180 degrees centigrade.

　　1.防腐涂層:維護外鋼管，防止腐蝕，延長鋼管使用壽命。

　　1. Anti corrosion coating: maintain the outer steel pipe to prevent corrosion and extend the service life of steel pipe.

　　2.外保護鋼管:保護保溫層免受地下水腐蝕，支撐運行管道，并承受一定的外載荷，以保證運行管道的正常運行。

　　2. External protection steel pipe: protect the insulation layer from groundwater corrosion, support the operation pipeline and bear certain external load to ensure the normal operation of the operation pipeline.

　　3.聚氨酯發(fā)泡層:保證介質溫度和外管表面溫度保持正常。

　　3. Polyurethane foam layer: ensure that the medium temperature and the surface temperature of the outer tube are kept normal.

　　4.隔離反射層:確保有機泡沫數據不進入無機剛性高溫層;在耐高溫層中反射部分熱量。

　　4. isolation reflective layer: ensure that the organic foam data do not enter the inorganic rigid high temperature layer, and reflect some heat in the high temperature resistant layer.

　　5.無機硬保溫層:耐高溫，保證有機保溫層之間的界面溫度，保證泡沫不碳化。

　　5. inorganic hard insulation: high temperature, ensure the interface temperature between the organic insulation layer, ensure that the foam is not carbonized.

　　6.減阻層:保證工作鋼管受熱膨脹，受冷收縮，自由移動。

　　6. Drag reduction layer: ensure that the working steel pipe expands when heated, shrinks when cooled and moves freely.

　　7.操作鋼管:保證輸送介質的正常運行。

　　7. Operation of steel pipe: ensure the normal operation of transmission medium.
