聚氨酯保溫鋼管黑色外殼和黃色外殼有什麼區(qū)別
What's the difference between black and yellow polyurethane insulating steel pipes
聚氨酯保溫鋼管外殼有黑色的也有黃色的，二者有什麼區(qū)別的，上面我們就介紹一下。
There are black and yellow polyurethane insulating steel tube shell. What's the difference between them? Let's introduce them above.
黃夾克保溫管構(gòu)造次要包括任務(wù)鋼管層，聚氨酯保溫層和高密度聚乙烯維護層。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。黑色的稱之爲(wèi)黑夾克保溫管，黃色的稱之爲(wèi)黃夾克保溫管。其作用一是維護聚氨酯保溫層免遭機械硬物毀壞，二是防腐、防水。高密度聚乙烯聚氨酯發(fā)泡保溫鋼管執(zhí)行：SY/T114-2000和SY/T115-2001規(guī)范。
The construction of yellow jacket insulation pipe 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. Black jacket insulation pipe is called black jacket insulation pipe, yellow jacket insulation pipe is called yellow jacket insulation pipe. Its function is to maintain the polyurethane insulation layer from the destruction of mechanical hard objects, and the second is anti-corrosion and waterproof. High density polyethylene polyurethane foamed insulation steel pipe execution: SY/T114-2000 and SY/T115-2001 specification.
大家都曉得聚氨酯保溫鋼管中的任務(wù)鋼管類型次要有螺旋鋼管和無縫鋼管兩種，那麼這兩種鋼管詳細什麼時分采用
Everyone knows that in polyurethane thermal insulation steel pipe, the secondary types of steel pipe are spiral steel pipe and seamless steel pipe. When should these two kinds of steel pipe be used in detail?
承壓范圍偏小是采用螺旋鋼管;螺旋鋼管是一種焊接鋼管，本身承壓才能就不強，多作爲(wèi)輸水管道停止運用。
Spiral steel pipe is a kind of welded steel pipe, which is not strong enough to bear pressure. It is mostly used as a water conveyance pipeline.
承壓偏大采用無縫鋼管;無縫鋼管就是沒有焊縫的鋼管，承壓才能比擬強，多作爲(wèi)蒸汽管道及石油、自然氣管道停止運用。
Seamless steel pipes are used for large pressure bearing capacity; seamless steel pipes are those without welds, which can be used as steam pipes and oil and natural gas pipelines.
