Large-scale polyurethane insulating pipe consumer company uses imported high-pressure complete sets of polyurethane foaming equipment to consume the three-in-one direct-buried insulating pipe with excellent overall performance, strict implementation of steel pipe surface rust removal and external corona treatment process, further improving the bonding performance of insulating pipe. The insulation layer material is rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully filled the gap between the steel pipe and the casing, and has certain bonding strength, so that the steel pipe, the outer sleeve pipe and the insulation layer can form a solid whole between the three. Polyurethane foam has good mechanical properties and thermal insulation properties. Under normal conditions, it can withstand temperatures of 120 degrees Celsius. After modification or combination with other thermal insulation materials, polyurethane foam can withstand temperatures of 180 degrees Celsius. Direct-buried prefabricated insulating pipes have outstanding advantages over traditional insulating pipes.

：1、保溫性能好，熱損失僅為傳統(tǒng)管材的25%，長期運(yùn)轉(zhuǎn)可節(jié)約大量能源，顯著降低能源本錢。

1. Good thermal insulation performance, heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy, significantly reduce energy costs.

2、具有很強(qiáng)的防水和耐腐蝕才能，不需附設(shè)管溝，可直接埋入公開或水中，施工煩瑣疾速，綜合造價低。

2. It has strong ability of waterproofing and corrosion resistance. It can be directly buried in open or water without installing pipe trenches. The construction is tedious and fast, and the comprehensive cost is low.

3、在低溫條件下也具有良好的耐腐蝕和耐沖擊性，可直接埋入公開凍土。

3. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in open frozen soil.

4、運(yùn)用壽命可達(dá)30-50年，正確的裝置和運(yùn)用可使管網(wǎng)維修費(fèi)用極低。

4. The service life can reach 30-50 years. Correct installation and operation can make the maintenance cost of the pipeline network very low.

5、可設(shè)置報警系統(tǒng)，自動檢測管網(wǎng)滲漏毛病，精確指示毛病位置并自動報警。

5. An alarm system can be set up to automatically detect the leakage of the pipeline network, accurately indicate the location of the fault and automatically alarm.

聚氨酯直埋發(fā)泡保溫管-聚氨酯發(fā)泡保溫管泡沫具有良好的機(jī)械性能和絕熱聚氨酯保溫管應(yīng)用：聚氨酯保溫管用于室內(nèi)外各種管道，集中供熱管道，中央空調(diào)管道、化工、等工業(yè)管道的保溫、保冷工程。概述聚氨酯發(fā)泡保溫管自三十年代聚氨酯合成資料降生以來，不斷作為一種優(yōu)秀的絕熱保溫資料而得到疾速開展，其應(yīng)用范圍也越來越普遍，更由于其施工煩瑣、節(jié)能防腐效果顯著而被大量地用于各種供熱、制冷、輸油、輸汽等各種管道。大量地用于各種供熱、制冷、輸油、輸汽等各種管道

Polyurethane directly buried foam insulation tube - polyurethane foam insulation tube foam has good mechanical properties and insulation polyurethane insulation pipe application: polyurethane insulation pipe for indoor and outdoor pipes, central heating pipes, central air-conditioning pipe, chemical industry, and other industrial pipeline insulation and cold insulation works. This paper summarizes that polyurethane foamed insulation pipe has been developed rapidly as an excellent thermal insulation material since the birth of polyurethane synthetic data in the 1930s, and its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil transportation and steam transportation because of its cumbersome construction and remarkable energy-saving and anticorrosive effect. All kinds of pipelines. It is widely used in various heating, refrigeration, oil and steam pipelines.
