聚氨酯保温钢管适用范围中的劣势
Advantages of Polyurethane Thermal Insulation Pipe in Applicable Range
聚氨酯保温钢管次要用户保送热水、蒸汽等需求保温的气体或许液体，由于两头有一层保温棉，可以少量的降低保送进程的热损耗，外层皮子还可以防腐腐蚀，用以提升管道的运用寿命，目前曾经被少量的使用于液体、气体的保送管网， 化工管道保温工程石油、化工、集中供热热网、地方空调通风管道、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.
保温钢管依据构造次要有聚氨酯保温钢管和钢套钢保温管两种，二者的构造是完全不同的。
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.
一.聚氨酯保温钢管构造
Firstly, the construction of polyurethane insulating steel pipe
聚氨酯保温钢管由保送介质的，任务钢管、聚氨酯保温层、聚乙烯塑料外护管，经过设备顺次向外结合而成。
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.钢套钢保温管构造
Secondly, the construction of steel insulating pipe with steel sleeve
由保送介质的任务钢管、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、外防腐层经过设备顺次向外结合而成。
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.
In summary, all the above-mentioned Shandong Hipper Pipe Technology Development Co., Ltd. provides, want to know more about polyurethane insulation pipe manufacturers, welcome to pay attention to our website: http://www.sdhpgy.com Thank you for your support!
