冬天保温钢管的寄存
Storage of Thermal Insulation Steel Pipe in Winter
冬天气温到了零下，极端冰冷。冰冻时节关于 保温钢管是怎样过冬呢？一定会有人这样问，保温钢管是指对保温钢管内的介质停止保温防护的，但假如是曾经出产完的露天的保温钢管怎样存放才干让它们平安过冬呢？
In winter, the temperature is below zero and extremely cold. How do insulating steel pipes spend the winter in freezing season? Some people will ask that the insulation steel pipe means to stop the insulation protection of the medium inside the insulation steel pipe, but if it is the open-air insulation steel pipe that has been produced, how can it be stored so that they can survive the winter safely?
保温钢管在存放上普通是在常温下、防止阳光直晒的中央存放，可是到了冬天均匀温度在0度左右怎样保管呢？迷信办法是这样的，立冬后，把保温钢管按照一定的规矩摆放划一，摆放在车间内，再用苫布完全盖住，防止保温钢管间接接触阳光，在春季到来之间不能动苫布，以免保温钢管外皮裂开。
Insulating steel pipes are usually stored at room temperature to prevent direct sunshine, but how to keep them in winter when the uniform temperature is about 0 degrees? Superstition is like this. After the beginning of winter, the insulating steel pipes are laid uniformly according to certain rules and placed in the workshop. Then they are completely covered with rayon cloth to prevent the insulating steel pipes from indirectly contacting the sunshine. The rayon cloth should not be moved between the arrival of spring so as to prevent the outer skin of the insulating steel pipes from cracking.
夹克聚氨酯保温钢管常用的保温资料是硬质聚氨脂泡沫塑料，适用温度爲－185～120℃。这种资料质地坚实，爲进步其强度，在隔热层里面加敷一层高密度聚乙烯层，构成复合资料构造，以防止地下水渗入保温层内。夹克保温管构造首要包括任务钢管层，聚氨酯保温层和高密度聚乙烯维护层。其中里面的一层由预制成一定壁厚的黑色或黄色聚乙烯塑料资料掩盖。
The commonly used insulation material for jacket polyurethane insulating steel pipe is rigid polyurethane foam, and the applicable temperature is - 185 - 120 C. In order to improve its strength, a layer of high density polyethylene (HDPE) is added to the thermal insulation layer to form a composite data structure to prevent groundwater from seeping into the thermal insulation layer. The construction of jacket insulation pipe mainly includes task steel pipe layer, polyurethane insulation layer and high density polyethylene maintenance layer. One of the inner layers is covered by black or yellow polyethylene plastic materials prefabricated to a certain wall thickness.
