聚氨酯保温钢管来做管道保温原因
Polyurethane insulation steel pipe for insulation reasons
聚氨酯保温钢管外护管首要是选用聚乙烯出产而成，因而人们也习气称为聚乙烯外套管。
Polyurethane insulating steel pipe exterior protection pipe is mainly made of polyethylene, so people are also accustomed to call polyethylene exterior casing.
聚乙烯外套管选用高密度聚乙烯材料制成，具有极高的机械强度和优良的耐腐蚀功能，可以维护管材在运送、装置及运用过程中防止因外界因素而形成的损坏。制作外套管应增加抗氧剂、紫外线稳定剂和炭黑等
Polyethylene outer sleeve is made of high density polyethylene material, which has high mechanical strength and excellent corrosion resistance. It can maintain the pipeline in transportation, installation and application process to prevent damage caused by external factors. The outer tube should be added with antioxidants, UV stabilizers and carbon black.
目前聚氨酯保温钢管首要作为保温管道进行运用，首要有以下优势。
At present, polyurethane insulation pipes are mainly used as insulation pipes.
1.可以下降工程造价。据有关部门测算，双控制供热管道，一般情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., we can reduce the project cost. According to the calculation of relevant departments, the cost of double-control heating pipeline can generally be reduced by 25% (using FRP as maintenance layer) and 10% (using high density polyethylene as maintenance layer).
2.运用聚氨酯保温钢管，热损耗低，节约能源。聚氨酯保温钢管比其它曩昔常用的管道保温材料导热系数低得多，保温效果可以提高4-9倍。
2. use polyurethane heat preservation steel pipe, low heat loss and energy saving. The thermal conductivity of polyurethane insulating pipe is much lower than that of other commonly used pipe insulating materials in the past, and the thermal insulation effect can be increased by 4-9 times.
3.聚氨酯保温钢管防腐，绝缘功能好，运用寿命长。聚氨酯保温钢管因为聚氨酯硬质泡沫保温层严密地粘结在钢管外皮，隔绝了空气和水的进入，能起到杰出的防腐作用。
3. polyurethane thermal insulation steel pipe corrosion resistance, good insulation function, long service life. Polyurethane heat preservation steel pipes, because the rigid polyurethane foam insulation layer is tightly bonded to the outer skin of the steel pipe, can separate the air and water from entering, and can play an excellent anti-corrosive effect.
聚氨酯保温钢管的运用寿命可达50年以上，比传统的地沟敷设、架空敷设运用寿命高3-4倍。终，也是重要的一点：运用聚氨酯保温钢管占地少，施工快，有利于环境维护。聚氨酯保温钢管直接埋入地下，因而大大减少了工程占地，可以缩短工期约50%以上。
The service life of polyurethane insulating steel pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying. Ultimately, but also the most important point: the use of polyurethane insulation steel pipe occupies less land, construction is fast, conducive to environmental maintenance. Polyurethane insulating steel pipe is directly buried underground, which greatly reduces the project area and shortens the construction period by more than 50%.
