聚氨酯保温管不仅具有传统地沟和架空敷设管道难以比拟的先进技术、实用性能,而且还具有显著的社会效益和经济效益,也是供热节能的有力措施。预制直埋保温管采用直埋供热管道技术,标志着中国供热管道技术发展已经进入了新的起点。 随着世界能源的日益减少和需求日益增长,节能、减排、环保已成为全球发展的趋势,国家和个地方政府也大力提倡节能、减排、环保产品的开发、应用及产业化,建筑业用聚氨酯硬泡体保温材料是聚氨酯工业的一个重要分支,其特点是一材多用,同时具备保温、防水等功能。该类产品自20世纪60年代在欧洲建筑业应用以来已有40年历史,一些国家还通过立法把聚氨酯作为建筑业指定的保温防水用材。
Polyurethane insulation pipe not only has the advanced technology and practical performance that traditional trench and overhead laying pipeline can't match, but also has remarkable social and economic benefits, which is also a powerful measure of heating and energy saving. The technology of directly buried heat supply pipeline is adopted for prefabricated directly buried thermal insulation pipe, which indicates that the development of heat supply pipeline technology in China has entered a new starting point. With the decreasing of energy and increasing demand in the world, energy conservation, emission reduction and environmental protection have become the trend of global development. The national and local governments also strongly advocate the development, application and industrialization of energy-saving, emission reduction and environmental protection products. Polyurethane rigid foam thermal insulation materials for construction industry is an important branch of polyurethane industry, which is characterized by multi-purpose, thermal insulation, thermal insulation, and so on Waterproof and other functions. This kind of product has been used in European construction industry for 40 years since 1960s. Some countries also take polyurethane as the insulation and waterproof material specified by the construction industry through legislation.
聚氨保温管道中首当其冲的就是钢套钢保温钢管,它采用没有混凝土结构的情况下也可以进行地下直埋的方式,即工作钢管的热膨胀在外管内进行,从而降低了材料成本,缩短了施工日期,并保障了供热管道的安全性,可以在不同温度环境下更安全的广泛应用,尤其适用于高温蒸汽管道项目。使用温度可达150℃-450℃ 钢套钢保温管是由外护钢管加钢管防腐、聚氨酯泡沫保温层及内工作钢管组合而成。钢套钢蒸气复合保温管适用于输送2.5MPa、350摄氏度以下的蒸汽或其它介质,该产品用钢管做外防护层,具有强度高,不易损坏,施工检修简便,使用寿命长的优点

The first thing to bear the brunt of the polyurethane insulation pipeline is the steel jacket steel insulated steel pipe, It can also be directly buried underground without concrete structure, that is, the thermal expansion of working steel pipe is carried out in the outer pipe, so as to reduce the material cost, shorten the construction date, and ensure the safety of the heat supply pipeline. It can be widely used in different temperature environment, especially for high temperature steam pipeline project. The steel sleeve steel insulation pipe with a temperature of up to 150 -450 C is made up of an external protective steel pipe, a steel pipe anticorrosion, a polyurethane foam insulation layer and an internal working steel pipe. Steel sleeve steel steam composite insulation pipe is suitable for conveying steam or other media below 2.5MPa and 350 ℃. The product uses steel pipe as outer protective layer, which has the advantages of high strength, easy maintenance and long service life.
钢套钢保温管保温结构依据滑动方式不同分为:内滑动式与外滑动式 1、内滑动式:保温结构由工作钢管、硅酸铝、减阻层、微孔硅酸钙、隔热层、不锈钢紧固钢带、铝箔反射层、聚氨酯保温层、外套钢管、外防腐层组成。 2、外滑动式:保温结构由工作钢管、玻璃棉保温隔热层、铝箔反射层、不锈钢紧固带、滑动导向支架、空气保温层、外护钢管、外防腐层组成。
According to different sliding modes, the thermal insulation structure of steel sheathed steel insulation pipe is divided into internal sliding type and external sliding type. 1. Internal sliding type: the insulation structure is composed of working steel pipe, aluminum silicate, drag reducing layer, microporous calcium silicate, thermal insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe and external anti-corrosion coating. 2. External sliding type: the thermal insulation structure is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, external steel pipe and external anti-corrosion coating.
聚氨酯直埋保温管由于具有恒久的耐腐蚀抗老化的特征,在应用中备受人们的欢迎,故而有着很大的需求市场存在,也因此对于聚氨酯保温管的生产有着很大的生产数额要求。对于聚氨酯保温管的生产加工,需要针对具体用途与结构进行处理。对于有内管和外套管的保温层实施,聚氨酯发泡保温管通常是在两管之间直接灌注发泡浆料,一次成型发泡。
Polyurethane directly buried insulation pipe has been widely welcomed because of its long history of corrosion resistance and anti-aging. Therefore, there is a great demand for the market. Therefore, there is a large demand for production of polyurethane insulation pipes. For the production and processing of polyurethane insulation pipe, it is necessary to deal with the specific use and structure. For the insulation layer with inner pipe and outer pipe, polyurethane foam insulation pipe is usually filled with foam slurry directly between the two pipes to form foam at one time.
