保温管是绝热管道的简称,保温 管用于液体、气体及其他介质的输送,在石油、化工、航天、温泉~军事、集中供热、空调、市政等管道的绝热工程保温。那济南保温管有什么特点呢?今天海珀管业小编带大家了解一下:
Insulation pipe is the abbreviation of heat insulation pipeline. It is used for the transportation of liquid, gas and other media. It is used in thermal insulation engineering of petroleum, chemical, aerospace, hot spring ~ military, central heating, central air conditioning, municipal pipeline, etc. What are the characteristics of Jinan insulation pipe? Today, Harper pipe industry will take you to know:
High temperature prefabricated directly buried insulation pipe - Advantages
1 具有很强的耐腐蚀和防水能力,综合造价低
It has strong corrosion resistance and water-proof ability and low comprehensive cost
According to the calculation of relevant departments, under normal circumstances, the double pipe heating pipeline can reduce the project cost by about 25% (using glass fiber reinforced plastic as the protective layer) and 10% (using high-density polyethylene as the protective layer).
2 热损耗低,节约能源。 热损耗仅为传统管材的25%
2. Low heat loss and energy saving. The heat loss is only 25% of the traditional pipe material
直埋保温管 导热系数 0.022kcal/m.h.℃ 憎水率 0.03kg/cm³
The thermal conductivity of directly buried insulation pipe is 0.022kcal/m.h. ℃ and the hydrophobic rate is 0.03kg/cm3
3 使用寿命长
3 long service life
Correct installation and use can make the service life of pipe network reach 30-50 years, and the maintenance cost is very low.
4 占地少 施工快 有利于环境保护
4. Less land occupation and faster construction is conducive to environmental protection
能减少土方开挖量50%以上 减少土建砌筑和混凝土量90%
It can reduce the volume of earth excavation by more than 50% and reduce the amount of civil masonry and concrete by 90%

It is much lower than other insulation pipe materials used in the past, and the insulation effect is increased by 4 ~ 9 times. Moreover, its water absorption rate is very low, about 0.2kg/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 high-density polyethylene or glass fiber reinforced plastic protective shell with good waterproof performance, have changed the situation of "wearing wet cotton padded jacket" in traditional trench laying heating pipeline, and greatly reduced the overall heat loss of heat supply pipeline. The heat loss of heat supply network is 2%, less than the international standard of 10%.
Anticorrosion, good insulation and long service life.
The 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 foam cells are closed, water absorption is very small. High density polyethylene (HDPE) and glass fiber reinforced plastic (FRP) shells have good anticorrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is hard to be eroded by the outside air and water. As long as the internal water quality of the pipeline is well treated, according to foreign information, the service life of high-temperature prefabricated directly buried insulation pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying and overhead laying.
It has the advantages of less land occupation, fast construction and environmental protection.
The directly buried heat supply pipeline does not need to build a huge trench, but only needs to bury the insulation pipe underground. Therefore, the land occupation of the project is greatly reduced, the amount of earthwork excavation is reduced by more than 50%, and the amount of civil masonry and concrete is reduced by 90%. At the same time, the insulation pipe processing and field trenching are carried out in parallel, and the construction period can be shortened by more than 50% by only using field joints.
