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.

　　保温管聚氨酯直接埋地保温管，又称“管中管”，由“两步法”组成，由高密度聚乙烯外养护层、聚氨酯硬质泡沫塑料管和钢管组成。

　　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.

　　保温材料为60kg/m3至80kg/m3的硬质聚氨酯泡沫塑料，填充钢管与套管之间的空间，具有一定的粘结强度，使钢管、外套管与保温材料形成一个整体。保温钢管泡沫具有优良的机械保温和保温功能，通常120℃可以改性或与其他保温材料结合使用可以承受180℃。保温材料为60kg/m3至80kg/m3的硬质聚氨酯泡沫塑料，填充钢管与套管之间的空间，具有一定的粘结强度，使钢管、外套管与保温材料形成一个整体。保温钢管泡沫具有优良的机械保温和保温功能，通常120℃可以修改或与其他保温数据相结合的保温钢管

　　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.防腐涂层:维护外钢管，防止腐蚀，延长钢管使用寿命。

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

　　2.外保护钢管:保护保温层免受地下水腐蚀，支撑运行管道，并承受一定的外载荷，以保证运行管道的正常运行。

　　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.聚氨酯发泡层:保证介质温度和外管表面温度保持正常。

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

　　4.隔离反射层:确保有机泡沫数据不进入无机刚性高温层;在耐高温层中反射部分热量。

　　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.无机硬保温层:耐高温，保证有机保温层之间的界面温度，保证泡沫不碳化。

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

　　6.减阻层:保证工作钢管受热膨胀，受冷收缩，自由移动。

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

　　7.操作钢管:保证输送介质的正常运行。

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