聚氨酯保溫鋼管如何運(yùn)用
How to Use Polyurethane Thermal Insulation Pipe
1.下降工程造價(jià)，雙控制供熱管道，普通狀況下可以下降工程造價(jià)的25%(選用玻璃鋼做維護(hù)層)和10%(選用高密度聚乙烯做維護(hù)層)左右。
1. To reduce the cost of construction, double-control 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. 熱損耗低，浪費(fèi)動(dòng)力，聚氨酯保溫鋼管其導(dǎo)熱系數(shù)爲(wèi)：比其他曩昔常用的管道保溫資料低得多，保溫作用提高4~9倍。再有其吸水率很低，約爲(wèi)0.2kg/m2。吸水率低的緣由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，加上保溫層和里面防水功能好的高密度聚乙烯或玻璃鋼維護(hù)殼，改動(dòng)了傳統(tǒng)地溝敷設(shè)供熱管道“穿濕棉襖”的狀況，大大增加了供熱管道的全體熱損耗，熱網(wǎng)熱損失爲(wèi)2%，小于世界10%的標(biāo)準(zhǔn)要求。
2. Low heat loss and waste of power. The thermal conductivity of polyurethane insulating pipe is much lower than that of other commonly used pipelines, and its thermal insulation effect is increased by 4-9 times. And its water absorption is very low, about 0.2 kg/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 waterproof high density polyethylene or FRP maintenance shell, have changed the situation of traditional trench laying heating pipeline "wearing wet cotton jacket", greatly increased the overall heat loss of heating pipeline, heat loss of heating network is 2%, less than the world standard requirements of 10%.
3.聚氨酯保溫鋼管具有防腐，絕緣功能好，運(yùn)用壽命長(zhǎng)。直埋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，隔絕了空氣和水的進(jìn)入，能起到出色的防腐作用。預(yù)制直埋保溫管同時(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.聚氨酯保溫鋼管外殼均具有出色的防腐.絕緣和機(jī)械功能。因此，任務(wù)鋼管外皮很舒服到外界空氣和水的腐蝕。鋼套鋼蒸汽保溫管只需管道外部水質(zhì)處置好，據(jù)國(guó)外資料引見(jiàn)，聚氨酪保溫管聚氨酪保溫管道的運(yùn)用壽命可達(dá)50年以上，比傳統(tǒng)的地溝敷設(shè).直埋保溫管廠(chǎng)家架空敷設(shè)運(yùn)用壽命高3~4倍
3. Polyurethane insulating steel pipe has anticorrosion, good insulation function and long service life. The directly buried insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which blocks the entry of air and water, and can play an excellent anti-corrosive effect. At the same time, the foam holes of the prefabricated directly buried insulating pipe are closed, and the water absorption is very small. High density polyethylene shell, FRP and PU insulating steel tube shell all have excellent anti-corrosion, insulation and mechanical functions. Therefore, the task steel pipe skin is very comfortable to the outside air and water corrosion. According to foreign data, the service life of polyurethane insulation pipe and polyurethane insulation pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying. Overhead laying service life of directly buried insulation pipe manufacturer is 3-4 times longer than that of traditional trench laying.
4.國(guó)外消費(fèi)聚氨酯保溫鋼管，直埋保溫管廠(chǎng)家均設(shè)有滲漏報(bào)警線(xiàn)，一旦管道某處發(fā)作滲漏，經(jīng)過(guò)報(bào)警線(xiàn)的傳導(dǎo)。便可在公用檢測(cè)儀表上顯示出保溫管道滲水.漏水的準(zhǔn)確方位及滲漏水平的巨細(xì)，以便通知檢滲人員矯捷處置漏水的管段，保證供熱管網(wǎng)的平安運(yùn)轉(zhuǎn)。
4. Foreign consumer polyurethane insulating steel pipes and directly buried insulating pipe manufacturers all have leakage alarm lines. Once leakage occurs somewhere in the pipeline, it is transmitted by the alarm lines. In order to inform the inspectors to deal with the leaking pipeline quickly and ensure the safe operation of the heating network, the exact position and the size of the leaking pipeline can be displayed on the public inspection instrument.
