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至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 from 0.013 to 0.03kcal/m?H?OC, which is much lower than other commonly used pipeline thermal insulation data, and the thermal insulation effect is improved by 4-9 times. Another reason is that its low water absorption rate is about 0.2kg / m2.. The reason is that the obturator rate of polyurethane foam is as high as 92%. Low thermal conductivity and low water absorption, together with high density polyethylene (HDPE) or fiberglass reinforced plastics (FRP) maintenance shell with good insulation layer and external waterproofing performance, have changed the situation of traditional trench laying heating pipeline "wearing wet cotton jacket", greatly reducing the overall heat loss of heating pipeline, the heat loss of heating network is 2%, less than the international norm request of 10%.
3、防腐,绝缘性能好,运用寿命长。

3. Anti-corrosion, good insulation performance and long service life.
高温预制直埋保温管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,据国外材料引见,高温预制直埋保温管的运用寿命可达50年以上,比传统的地沟敷设、架空敷设运用寿命高3~4倍。
The high temperature prefabricated directly buried insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which can isolate the infiltration of air and water, and can play a good anti-corrosive effect. At the same time, its foaming holes are closed and its water absorption is very small. High density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical properties. Therefore, it is very difficult for the outer skin of the working steel pipe to be corroded by the external air and water. According to foreign materials, the service life of high temperature prefabricated directly buried insulating pipes can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying.
4、占地少,施工快,有利环境维护。
4. It occupies less land, constructs quickly and maintains favorable environment.
直埋供热管道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 heating pipelines do not need to build huge trenches. They only need to bury insulating pipes openly, which greatly reduces the construction area, reduces the amount of earthwork excavation by more than 50%, and reduces the amount of civil masonry and concrete by 90%. At the same time, the processing of insulating pipes and digging ditches on site are stopped in parallel, and the construction period can be shortened by more than 50% with only on-site joints.
5、平安。
5. Peace.
可依据客户请求装置渗漏报警线,一旦管道某处发作渗漏,经过报警线的传导,便可在专用检测仪表上显现出保温管道渗水、漏水的精确位置及渗漏水平的大小,以便通知检渗人员疾速处置漏水的管段,保证供热管网的平安运转。如今我们也能够自主消费制造带预警线的直埋保温管,补偿了之前无预警系统的这一空缺。
The leakage alarm line can be set up according to the customer's request. Once the leakage occurs somewhere in the pipeline, through the transmission of the alarm line, the exact position and leakage level of the insulation pipeline can be displayed on the special detection instrument, so as to inform the inspectors to quickly dispose of the leakage pipeline section and ensure the safe operation of the heating pipeline network. Now we can also manufacture directly buried insulating pipes with early warning line by ourselves, which compensates for the vacancy of no early warning system before.
