      聚氨酯保溫鋼管適用范圍中的劣勢
      Advantages of Polyurethane Thermal Insulation Pipe in Applicable Range
      聚氨酯保溫鋼管次要用戶保送熱水、蒸汽等需求保溫的氣體或許液體,由于兩頭有一層保溫棉,可以少量的降低保送進(jìn)程的熱損耗,外層皮子還可以防腐腐蝕,用以提升管道的運(yùn)用壽命,目前曾經(jīng)被少量的使用于液體、氣體的保送管網(wǎng), 化工管道保溫工程石油、化工、集中供熱熱網(wǎng)、地方空調(diào)通風(fēng)管道、市政工程等。
      Secondary users of polyurethane insulating steel pipes deliver hot water, steam and other gases or liquids that need heat preservation. Because there is a layer of insulating cotton at both ends, it can reduce the heat loss in the process of delivery in a small amount, and the outer skin can also prevent corrosion, so as to improve the service life of pipelines. At present, it has been used in a small amount of liquids and gases. Safeguard pipeline network, chemical pipeline insulation engineering petroleum, chemical industry, central heating network, local air conditioning and ventilation pipeline, municipal engineering, etc.
      保溫鋼管依據(jù)構(gòu)造次要有聚氨酯保溫鋼管和鋼套鋼保溫管兩種,二者的構(gòu)造是完全不同的。
      Thermal insulating steel pipes are mainly composed of polyurethane thermal insulating steel pipes and steel sleeve thermal insulating steel pipes. Their structures are totally different.
      聚氨酯保溫鋼管廠家
      一.聚氨酯保溫鋼管構(gòu)造
      Firstly, the construction of polyurethane insulating steel pipe
      聚氨酯保溫鋼管由保送介質(zhì)的,任務(wù)鋼管、聚氨酯保溫層、聚乙烯塑料外護(hù)管,經(jīng)過設(shè)備順次向外結(jié)合而成。
      Polyurethane insulating steel pipe is composed of delivery medium, task steel pipe, polyurethane insulating layer and polyethylene plastic exterior protective pipe, which are combined outward sequentially by equipment.
      第二.鋼套鋼保溫管構(gòu)造
      Secondly, the construction of steel insulating pipe with steel sleeve
      由保送介質(zhì)的任務(wù)鋼管、玻璃棉保溫隔熱層、鋁箔反射層、不銹鋼緊固帶、滑動導(dǎo)向支架、空氣保溫層、外護(hù)鋼管、外防腐層經(jīng)過設(shè)備順次向外結(jié)合而成。
      It is composed of task steel pipe, glass wool insulation layer, aluminium foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, external steel pipe and external anti-corrosion layer, which are combined outward by the equipment sequentially.
