六个方法教你鉴别聚氨酯发泡保温钢管
Six Methods to Identify Polyurethane Foamed Insulation Pipe
聚氨酯发泡保温钢管具有容重轻、强度高、绝热、隔音、阻燃、耐寒、防腐、不吸水、施工简洁快捷等优异特点，已成爲建筑、运输、石油、化工、电力、冷藏等工业部门绝热保温、防水堵漏、密封等不可短少的资料。
Polyurethane foamed insulating steel pipe has the advantages of light bulk density, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anticorrosion, non-water absorption, simple and fast construction, etc. It has become an indispensable material for insulation, heat preservation, waterproof, leak plugging and sealing of industrial departments such as construction, transportation, petroleum, chemical industry, electric power, refrigeration, etc.
1、导热系数小：
1. Low thermal conductivity:
聚氨酯泡沫的导热系数在保温资料中是极低的，因而能使物料的热丧失增添到极低限制。
The thermal conductivity of polyurethane foam is very low in thermal insulation data, which makes the heat loss of material increase to a very low limit.
2、防水、防腐、耐老:
2. Waterproof, anti-corrosive and anti-aging:
由于聚氨酯泡沫的闭孔率达92%以上,因而,用聚氨酯泡沫作爲直埋管道的保温层,不只可以起保温隔热效果，并且能无效地防止水，湿气以及其它多种腐蚀性液体、气体的渗透，防止微生物的繁衍和展开。聚氨酯保温管以其优良的功用，方便的施工及运用年限长而倍受人们欢送。
As the polyurethane foam has a closed porosity of more than 92%, polyurethane foam is used as the insulation layer of directly buried pipes, not only can play the role of thermal insulation, but also can effectively prevent water, moisture and other kinds of corrosive liquids and gases infiltration, and prevent microbial propagation and expansion. Polyurethane insulating pipes are welcomed by people for their excellent function, convenient construction and long service life.
1、聚氨酯发泡保温钢管保温功用好，热丧失仅爲传统管材的25%，临时运转可节省很多动力，明显降低动力本钱。
1. Polyurethane foamed insulating steel pipe has good heat preservation function, and its heat loss is only 25% of the traditional pipe. Temporary operation can save a lot of power and obviously reduce the power cost.
2、具有很强的防水和耐腐蚀才干，不需附设管沟，可间接埋上天下或水中，施工简洁迅速，综合造价低。
2. It has strong ability of waterproofing and corrosion resistance. It can be buried in the world or water indirectly without additional pipe trenches. It has the advantages of simple and rapid construction and low comprehensive cost.
3、在高温条件下也具有出色的耐腐蚀和耐冲击性，可间接埋上天下冻土。
3. It also has excellent corrosion resistance and impact resistance under high temperature, and can be buried indirectly in the world's frozen soil.
4、运用寿命可达30-50年，正确的装置和运用可使管网修缮费用极低。
4. The service life can be up to 30-50 years. Correct installation and operation can make the cost of repairing the pipeline network very low.
5、可设置报警零碎，自动检测管网渗漏缺点，精确指示缺点地位并自动报警。
5. It can set up alarm fragments, automatically detect leakage defects of pipeline network, accurately indicate the position of defects and automatically alarm.
6、运用寿命可达30-50年。管径：DN15—DN600厚度:15--50mm 用途:集中供热管道、制冷管道、工业管道等。
6. The service life can reach 30-50 years. Diameter: DN15 - DN600 Thickness: 15 - 50mm Usage: Central heating pipeline, refrigeration pipeline, industrial pipeline, etc.
