濟(jì)南保溫管有什么特點(diǎn)呢？今天海珀管業(yè)小編帶大家了解一下：
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:
高溫預(yù)制直埋保溫管-優(yōu)勢(shì)特點(diǎn)
High temperature prefabricated directly buried insulation pipe - Advantages
1 具有很強(qiáng)的耐腐蝕和防水能力，綜合造價(jià)低

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).

比其他過去常用的保溫管道材料低得多，保溫效果提高4~9倍。再有其吸水率很低，約為0．2kg/m2。吸水率低的原因是由于聚氨酯泡沫的閉孔率高達(dá)92%左右。低導(dǎo)熱系數(shù)和低吸水率，加上保溫層和外面防水性能好的高密度聚乙烯或玻璃鋼保護(hù)殼，改變了傳統(tǒng)地溝敷設(shè)供熱管道“穿濕棉襖”的狀況，大大減少了供熱管道的整體熱損耗，熱網(wǎng)熱損失為2%，小于10%的標(biāo)準(zhǔn)要求。
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%.
防腐，絕緣性能好，使用壽命長。
Anticorrosion, good insulation and long service life.
保溫管由于聚氨酯硬質(zhì)泡沫保溫層緊密地粘結(jié)在鋼管外皮，隔絕了空氣和水的滲入，能起到良好的防腐作用。同時(shí)它的發(fā)泡孔都是閉合的，吸水性很小。高密度聚乙烯外殼、玻璃鋼外殼均具有良好的防腐、絕緣和機(jī)械性能。因此，工作鋼管外皮很難受到外界空氣和水的侵蝕。只要管道內(nèi)部水質(zhì)處理好，據(jù)國外資料介紹，高溫預(yù)制直埋保溫管的使用壽命可達(dá)50年以上，比傳統(tǒng)的地溝敷設(shè)、架空敷設(shè)使用壽命高3~4倍。
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.
占地少，施工快，有利環(huán)境保護(hù)。
It has the advantages of less land occupation, fast construction and environmental protection.
直埋供熱管道不需要砌筑龐大的地溝，只需將保溫管埋人地下，因此大大減少了工程占地，減少土方開挖量約50%以上，減少土建砌筑和混凝土量90%。同時(shí)，保溫管加工和現(xiàn)場(chǎng)挖溝平行進(jìn)行，只需現(xiàn)場(chǎng)接頭，可以縮短工期約50%以上。
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.
