聚氨酯保温钢管如何运用
How to Use Polyurethane Thermal Insulation Pipe
1.下降工程造价，双控制供热管道，普通状况下可以下降工程造价的25%(选用玻璃钢做维护层)和10%(选用高密度聚乙烯做维护层)左右。
1. To reduce the cost of construction, double-control heating pipeline can reduce the cost of construction by 25% (using FRP as maintenance layer) and 10% (using high density polyethylene as maintenance layer) under normal conditions.
2. 热损耗低，浪费动力，聚氨酯保温钢管其导热系数爲：比其他曩昔常用的管道保温资料低得多，保温作用提高4~9倍。再有其吸水率很低，约爲0.2kg/m2。吸水率低的缘由是由于聚氨酯泡沫的闭孔率高达92%左右。低导热系数和低吸水率，加上保温层和里面防水功能好的高密度聚乙烯或玻璃钢维护壳，改动了传统地沟敷设供热管道“穿湿棉袄”的状况，大大增加了供热管道的全体热损耗，热网热损失爲2%，小于世界10%的标准要求。
2. Low heat loss and waste of power. The thermal conductivity of polyurethane insulating pipe is much lower than that of other commonly used pipelines, and its thermal insulation effect is increased by 4-9 times. And its water absorption is very low, about 0.2 kg/m2. The reason for low water absorption is that the polyurethane foam has a closed porosity of about 92%. Low thermal conductivity and low water absorption, together with insulation layer and waterproof high density polyethylene or FRP maintenance shell, have changed the situation of traditional trench laying heating pipeline "wearing wet cotton jacket", greatly increased the overall heat loss of heating pipeline, heat loss of heating network is 2%, less than the world standard requirements of 10%.
3.聚氨酯保温钢管具有防腐，绝缘功能好，运用寿命长。直埋保温管由于聚氨酯硬质泡沫保温层紧密地粘结在钢管外皮，隔绝了空气和水的进入，能起到出色的防腐作用。预制直埋保温管同时它的发泡孔都是闭合的，吸水性很小。高密度聚乙烯外壳.玻璃钢.聚氨酯保温钢管外壳均具有出色的防腐.绝缘和机械功能。因此，任务钢管外皮很舒服到外界空气和水的腐蚀。钢套钢蒸汽保温管只需管道外部水质处置好，据国外资料引见，聚氨酪保温管聚氨酪保温管道的运用寿命可达50年以上，比传统的地沟敷设.直埋保温管厂家架空敷设运用寿命高3~4倍
3. Polyurethane insulating steel pipe has anticorrosion, good insulation function and long service life. The directly buried insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which blocks the entry of air and water, and can play an excellent anti-corrosive effect. At the same time, the foam holes of the prefabricated directly buried insulating pipe are closed, and the water absorption is very small. High density polyethylene shell, FRP and PU insulating steel tube shell all have excellent anti-corrosion, insulation and mechanical functions. Therefore, the task steel pipe skin is very comfortable to the outside air and water corrosion. According to foreign data, the service life of polyurethane insulation pipe and polyurethane insulation pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying. Overhead laying service life of directly buried insulation pipe manufacturer is 3-4 times longer than that of traditional trench laying.
4.国外消费聚氨酯保温钢管，直埋保温管厂家均设有渗漏报警线，一旦管道某处发作渗漏，经过报警线的传导。便可在公用检测仪表上显示出保温管道渗水.漏水的准确方位及渗漏水平的巨细，以便通知检渗人员矫捷处置漏水的管段，保证供热管网的平安运转。
4. Foreign consumer polyurethane insulating steel pipes and directly buried insulating pipe manufacturers all have leakage alarm lines. Once leakage occurs somewhere in the pipeline, it is transmitted by the alarm lines. In order to inform the inspectors to deal with the leaking pipeline quickly and ensure the safe operation of the heating network, the exact position and the size of the leaking pipeline can be displayed on the public inspection instrument.
