冬天保溫鋼管的寄存
Storage of Thermal Insulation Steel Pipe in Winter
冬天氣溫到了零下，極端冰冷。冰凍時(shí)節(jié)關(guān)于 保溫鋼管是怎樣過冬呢？一定會(huì)有人這樣問，保溫鋼管是指對保溫鋼管內(nèi)的介質(zhì)停止保溫防護(hù)的，但假如是曾經(jīng)出產(chǎn)完的露天的保溫鋼管怎樣存放才干讓它們平安過冬呢？
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?
保溫鋼管在存放上普通是在常溫下、防止陽光直曬的中央存放，可是到了冬天均勻溫度在0度左右怎樣保管呢？迷信辦法是這樣的，立冬后，把保溫鋼管按照一定的規(guī)矩?cái)[放劃一，擺放在車間內(nèi)，再用苫布完全蓋住，防止保溫鋼管間接接觸陽光，在春季到來之間不能動(dòng)苫布，以免保溫鋼管外皮裂開。
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.
夾克聚氨酯保溫鋼管常用的保溫資料是硬質(zhì)聚氨脂泡沫塑料，適用溫度爲(wèi)－185～120℃。這種資料質(zhì)地堅(jiān)實(shí)，爲(wèi)進(jìn)步其強(qiáng)度，在隔熱層里面加敷一層高密度聚乙烯層，構(gòu)成復(fù)合資料構(gòu)造，以防止地下水滲入保溫層內(nèi)。夾克保溫管構(gòu)造首要包括任務(wù)鋼管層，聚氨酯保溫層和高密度聚乙烯維護(hù)層。其中里面的一層由預(yù)制成一定壁厚的黑色或黃色聚乙烯塑料資料掩蓋。
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.
