Before the research and development of polyurethane insulating pipes, the effect of heat preservation materials used in many industries was not very good, which led to wasting a lot of energy. Now, after the development of polyurethane insulating pipes, there has been a great change, mainly because its thermal insulation effect is very good. This is a new type of research and development in the new era. The reason why the thermal insulation data of type I can achieve such thermal insulation effect is that the design advantage of this kind of data is quite obvious. It adopts the method of three-layer design, and the vacuum disposal is used in the middle of the three-layer design form. This can be said to be the second thermal insulation system, so its thermal insulation is very obvious. Sex is so good, but when purchasing polyurethane insulation pipe, it is necessary to know some of its specifications and parameters.

在購置聚氨酯保溫管時需求留意其規(guī)格參數(shù)，一旦所選的產(chǎn)品達不到這種規(guī)格，在運用時就會比擬容易呈現(xiàn)問題，就規(guī)格參數(shù)方面允許偏向的值是一個相當(dāng)重要的局部，普通在管外面的包裝上是能看到允許偏向的值是幾的，不然極有可能會呈現(xiàn)購置回去之后，管于管之間銜接不起來，等到那個時分就比擬費事了，如今聚氨酯保溫管的允許偏向是在0.32mm，在這個范圍之內(nèi)的都是能夠放心運用的。

When purchasing polyurethane insulating pipe, it is necessary to pay attention to its specifications. Once the selected product fails to meet the specifications, it will be easier to present problems in operation. The allowable deviation value of specifications is a very important part. Generally, the allowable deviation value can be seen on the outside of the pipe packaging. However, it is very likely that after purchasing, the connection between the tubes will not be able to come up, and it will be more troublesome to wait until that time. Now the allowable bias of polyurethane insulation tubes is 0.32mm, which can be safely used in this range.

在選擇聚氨酯保溫管時要關(guān)于其的外徑、壁厚、重量等多方面停止思索，說的這幾個是更為根本的幾個參考規(guī)格，由于其采用的是全新的資料，因此在重量上是很輕盈的，如今重量方面給出的參考規(guī)格是3.724Kg，且外徑方面是285mm，更后的壁厚是4.4mm，規(guī)格參數(shù)跟這些差不多的就能夠在任何范疇里面運用。

When choosing polyurethane insulation pipe, we should stop thinking about its external diameter, wall thickness, weight and other aspects. These are the most fundamental reference specifications. Because it uses new information, it is very light in weight. The reference specifications given in weight are 3.724 Kg, and the external diameter is 285 M. M, the final wall thickness is 4.4mm, and the specifications can be used in any field with similar parameters.

在購置時是需求留意保溫層的厚度的，這個規(guī)格的值是決議聚氨酯保溫管的保溫性效果的一個很重要的方面，如今請求的值是在30mm，到達這樣的一個規(guī)格的是可以到達很好的保溫性效果的。

When purchasing, it is necessary to pay attention to the thickness of insulation layer. The value of this specification is a very important aspect to determine the thermal insulation effect of polyurethane insulating pipes. Now the requested value is 30mm. To reach such a specification, good thermal insulation effect can be achieved.
