聚氨酯保温钢管黑色外壳和黄色外壳有什麼区别
What's the difference between black and yellow polyurethane insulating steel pipes
聚氨酯保温钢管外壳有黑色的也有黄色的，二者有什麼区别的，上面我们就介绍一下。
There are black and yellow polyurethane insulating steel tube shell. What's the difference between them? Let's introduce them above.
黄夹克保温管构造次要包括任务钢管层，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。黑色的称之爲黑夹克保温管，黄色的称之爲黄夹克保温管。其作用一是维护聚氨酯保温层免遭机械硬物毁坏，二是防腐、防水。高密度聚乙烯聚氨酯发泡保温钢管执行：SY/T114-2000和SY/T115-2001规范。
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.
大家都晓得聚氨酯保温钢管中的任务钢管类型次要有螺旋钢管和无缝钢管两种，那麼这两种钢管详细什麼时分采用
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?
承压范围偏小是采用螺旋钢管;螺旋钢管是一种焊接钢管，本身承压才能就不强，多作爲输水管道停止运用。
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.
承压偏大采用无缝钢管;无缝钢管就是没有焊缝的钢管，承压才能比拟强，多作爲蒸汽管道及石油、自然气管道停止运用。
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.
