What I want to introduce to you today is the characteristics of polyurethane insulated steel pipe. I hope it can help you!

　　聚氨酯保溫鋼管的介紹：

　　Introduction of polyurethane insulated steel pipe:

　　1.防腐層：保護(hù)外鋼管避免腐蝕物腐蝕鋼管，延長鋼管使用壽命。

　　1. Anti corrosion coating: protect the outer steel pipe from corrosion and extend the service life of the steel pipe.

　　2.外護(hù)鋼管：保護(hù)保溫層免受地下水侵蝕，支撐工作管并能承受一定的外部荷載，保證工作管正常工作。

　　2. Steel pipe for external protection: protect the insulation layer from groundwater erosion, support the working pipe and bear certain external load to ensure the normal operation of the working pipe.

　　3.聚氨酯泡沫層：保證介質(zhì)溫度，保證外護(hù)管表面保持常溫。

　　3. polyurethane foam layer: ensure the temperature of the medium and ensure the surface of the outer tube is kept at room temperature.

　　4.阻隔、反射層：保證有機(jī)泡沫材料不進(jìn)入無機(jī)硬質(zhì)耐高溫層；反射耐高溫層部分熱量。

　　4. barrier and reflective layer: ensure that the organic foam material does not enter the inorganic hard and high-temperature resistant layer, and reflects some heat of the high temperature resistant layer.

　　5.無機(jī)硬質(zhì)保溫層：耐高溫，保證與有機(jī)保溫層之間的界面溫度，保證泡沫不被炭化。

　　5. inorganic hard insulation layer: high temperature resistance, ensure the interface temperature between the organic insulation layer and ensure that the foam is not carbonized.

　　6.減阻層：保證工作鋼管熱脹冷縮運(yùn)動。

　　6. Drag reduction layer: ensure the hot expansion and cold contraction movement of working steel pipe.

　　7.工作鋼管：保證輸送介質(zhì)正常流動。

　　7. Working steel pipe: ensure the normal flow of conveying medium.

　　聚氨酯保溫鋼管具有保溫、防水、防腐、絕熱、隔音、阻燃、耐寒、防腐、容量輕、強(qiáng)度高、施工簡便快捷、不怕植物根刺等優(yōu)異特點(diǎn)，已成為建筑、運(yùn)輸、石油、化工、電力、冷藏等工業(yè)部門絕熱保溫、防水堵漏、密封等不可缺少的材料。聚氨酯保溫鋼管用于室內(nèi)外各種管道，集中供熱管道，空調(diào)管道、化工、等工業(yè)管道的保溫、保冷工程、輸油管道工程、輸汽等管道工程。聚氨酯保溫鋼管能在0.6-1.2米凍土層內(nèi)直埋熱損失比普通的管道可降低40%以上，工作使用壽命比其它絕熱防腐材料提高3-5倍以上，壽命可以達(dá)到30-50年。

　　Polyurethane heat preservation steel pipe is characterized by high-efficiency heat preservation, waterproof, anticorrosion, heat insulation, sound insulation, flame retardant, cold resistance, anticorrosion, light capacity, high strength, simple and quick construction, no fear of plant roots, etc. it has become an indispensable material for heat insulation, water-proof and leakage stoppage, sealing and other industrial sectors such as construction, transportation, petroleum, chemical industry, power, refrigeration, etc. Polyurethane heat preservation steel pipe is used for heat preservation, cold insulation, oil transportation and steam transportation of various indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical and other industrial pipelines. Polyurethane insulated steel pipe can be directly buried in 0.6-1.2m frozen soil layer, the heat loss can be reduced by more than 40% compared with ordinary pipes, and the service life can be increased by more than 3-5 times compared with other heat insulation and anti-corrosion materials, and the service life can reach 30-50 years.

　　聚氨酯保溫鋼管具有良好的機(jī)械性能和絕熱性能，通常情況下可耐溫120℃,通過改性或與其它隔熱材料組合可耐溫180℃。

　　Polyurethane insulation steel pipe has good mechanical properties and thermal insulation performance. Generally, it can withstand temperature of 120 ℃ and 180 ℃ through modification or combination with other thermal insulation materials.
