Jinan heat preservation pipe is divided into three layers from inside to outside: working steel pipe layer. According to the design and user requirements, seamless steel pipe (gb8163-87) and spiral welded pipe (gb9711-88) are generally selected. SY / T 5038-92) and straight welded pipe (GB 3092-93). Polyurethane insulation pipe is made of high performance polyether polyol composite and polymethyl polyphenyl polyisocyanate by chemical reaction. Polyurethane heat preservation pipe has outstanding characteristics of light bulk density, high strength, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, non water absorption, simple and rapid construction, and has become an indispensable material for insulation, water-proof and leakage stoppage, sealing and other industrial fields such as construction, transportation, petroleum, chemical industry, electric power, refrigeration, etc. The preformed polyurethane insulation pipe shall have a lower thermal conductivity. When damped, it has no metamorphism, good heat resistance, corrosion-free metal, light and many cavities; it has certain mechanical strength and will not be damaged by external forces; it is easy to process and low cost. Commonly used thermal insulation materials are expanded perlite and its products, glass wool and its products, rock wool products, microporous calcium silicate, aluminum silicate fiber products, foam plastics, foam asbestos and so on.

　　聚氨酯直埋保溫管適用于室內(nèi)外管道、集中供熱管道、空調(diào)管道、化工、醫(yī)藥等工業(yè)管道的保溫、冷壓工程。聚氨酯泡沫保溫管聚氨酯合成材料的概述,30年代誕生以來(lái),一直作為一種優(yōu)良的隔熱材料,得到了快速發(fā)展,其應(yīng)用范圍也越來(lái)越廣泛,由于其施工簡(jiǎn)單和顯著的防腐效果,廣泛用于各種加熱、制冷、油、蒸汽等各種各樣的管道。大量供熱、制冷、輸油、蒸汽等管道。采用的噴丸工藝處理鋼管表面。鋼管的除銹等級(jí)達(dá)到gb8923-1988標(biāo)準(zhǔn)的SA2，鋼管的表面粗糙度達(dá)到GB6060.588標(biāo)準(zhǔn)的12.5微米。第二層:聚氨酯保溫層與高壓發(fā)泡機(jī)在鋼管外層之間形成空腔，一次性注入硬質(zhì)聚氨酯泡沫液。這就是通常所說(shuō)的管道發(fā)泡過(guò)程。其功能是防水，二是隔熱，三是承重。當(dāng)輸送介質(zhì)溫度為-50℃- 120℃時(shí)，保溫層為硬質(zhì)聚碳酸氫鹽泡沫。第三層:防腐鋼管是一種具有防腐性能的鋼管，具有良好的保溫性能。在建筑工程中得到了廣泛的應(yīng)用和推廣，并不斷得到完善和推廣。防腐保溫鋼管有不同的加工方式和方法。不同的加工方法決定了鋼管的不同性能和功能，使用范圍也會(huì)發(fā)生變化。防腐保溫鋼管的生產(chǎn)應(yīng)符合標(biāo)準(zhǔn)。不同的加工方法遵循不同的標(biāo)準(zhǔn)，但必須符合生產(chǎn)標(biāo)準(zhǔn)，必須嚴(yán)格執(zhí)行。

　　Polyurethane direct buried insulation pipe is suitable for indoor and outdoor pipes, central heating pipes, central air conditioning pipes, chemical industry, medicine and other industrial pipes. Polyurethane foam insulation tube polyurethane synthetic materials overview, since its inception in 30s, has been a good insulation material, has been developing rapidly, and its application scope is more and more widely. Because of its simple construction and remarkable energy saving and anti-corrosion effect, it is widely used in all kinds of pipes such as heating, refrigeration, oil, steam and so on. A large number of heating, cooling, oil transportation, steam and other pipelines. The surface of steel pipe is treated by advanced shot peening process. The derusting grade of steel pipe reaches SA2 of gb8923-1988 standard, and the surface roughness of steel pipe reaches 12.5 μ m of gb6060.588 standard. The second layer: polyurethane insulation layer and high pressure foaming machine form a cavity between the outer layer of steel tube, and injecting rigid polyurethane foam liquid at once. This is commonly known as the pipe foaming process. Its function is waterproof, heat insulation and load-bearing. When the conveying medium temperature is -50 - 120 C, the insulation layer is rigid polycarbonate foam. The third layer: anti-corrosion steel pipe is a kind of steel pipe with anti-corrosion performance, with good insulation performance. It has been widely used and promoted in the construction engineering, and has been continuously improved and promoted. There are different processing methods for anticorrosive and heat preservation steel pipes. Different processing methods determine different properties and functions of steel pipes, and the scope of use will also change. The production of anti-corrosion and heat preservation steel pipes shall meet the national standards. Different processing methods follow different standards, but they must meet the national production standards and be strictly implemented.
