1 降低工程造价.
1. Reduce the cost of construction.
据有关部门测算,双管制供热管道,普通状况下能够降低工程造价的25%(采用玻璃钢做维护层)和10%(采用高密度聚乙烯做维护层)左右.
According to the calculation of relevant departments, double-pipe 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,节约能源.
2. Low heat loss and energy saving.
其导热系数为:λ=0.013—0.03kcal/m·h·oC,比其他过去常用的管道保温资料低得多,保温效果进步4~9倍.再有其吸水率很低,约为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,加上保温层和外面防水性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”的情况,大大减少了供热管道的整体热损耗,热网热损失为2%,小于国际10%的规范请求.
Its thermal conductivity is: lambda =0.013 - 0.03kcal/m. H. OC, which is much lower than other commonly used pipe insulation materials. The insulation effect is progresses 4~9 times. The water absorption rate is very low. The reason why the water absorption rate of 0.2kg/m2. is low is that the polyurethane foam has a closed porosity of about 92%. Low thermal conductivity and low water absorbability, plus high density polyethylene or glass fibre reinforced plastic with good thermal insulation and water resistance outside. Maintenance shell, changed the traditional trench laying heating pipeline "wearing wet cotton jacket" situation, greatly reduced the overall heat loss of heating pipeline, heat loss of the heating network is 2%, less than 10% of the international norms.
3防腐,绝缘性能好,运用寿命长.
3. Anti-corrosion, good insulation and long service life.
由于聚氨酯硬质泡沫保温层严密地粘结在钢管外皮,隔绝了空气和水的渗入,能起到良好的防腐作用.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、玻璃钢外壳均具有良好的防腐、绝缘和机械性能.因而,工作钢管外皮很难遭到外界空气和水的腐蚀.只需管道内部水质处置好,运用寿命可达50年以上,比传统的地沟敷设、架空敷设运用寿命高3~4倍.

Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the infiltration of air and water can be isolated. It can play a good antiseptic effect. At the same time, the foamed holes are closed and the water absorbency is very small. The high density polyethylene shell and the FRP shell have good anticorrosion, insulation and mechanical properties. Therefore, the outer skin of the work steel pipe is difficult to be corroded by external air and water. The water quality inside the road is well disposed, and its service life can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying.
4.管道保温.占地少,施工快,有利环境维护.
4. Pipeline insulation. Less land occupation, faster construction, favorable environmental maintenance.
直埋供热管道保温不需求砌筑庞大的地沟,只需将保温管埋人公开,因而大大减少了工程占地,减少土方开挖量约50%以上,减少土建砌筑和混凝土量90%.同时,保温管加工和现场挖沟平行停止,只需现场接头,能够缩短工期约50%以上.
Directly buried heat-supply pipelines do not need to build huge trenches for heat preservation, only burying heat preservation pipelines openly, which greatly reduces the construction area, reduces the excavation of Earthwork by more than 50%, and reduces the amount of civil construction and concrete by 90%. Meanwhile, the processing of heat preservation pipelines and the excavation of trenches on site are stopped in parallel, and the construction period can be shortened by more than 50% with only on-site joints.
聚氨酯发泡保温管道具有容重轻、强度高、绝热、隔音、阻燃、耐寒、防腐、不吸水、施工烦琐快捷等优良特性,已成为石油、化工、电力、建筑、运输、冷藏等工业部门绝热保温、防水堵漏、密封等不可短少的产品.
Polyurethane foamed insulation pipeline has many excellent characteristics, such as light bulk density, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anticorrosion, non-water absorption, cumbersome and fast construction. It has become an indispensable product for thermal insulation, waterproof, leak plugging and sealing in petroleum, chemical, electric power, construction, transportation, refrigeration and other industrial sectors.
