The heat shrinkable tube is not the main machine in the path, but it plays the role of the cover path and the main machine parts in the pathway. As long as the appropriate proportion of the heat shrinkable tube, the ability to complete the maximum level of cover for the path. In this work, the small series will introduce you to the heat shrinkable tube of those root parameters.

Inner Diameter: We know that the cross section of the casing is cylindrical tubular, the inner diameter is the diameter of the inner wall, that is, the size of the interval between the inner walls, we generally use PHI to mark, because Phi is on the fortifications are used for punctuation diameter, and then the front to keep up with the number, indicating the value of the inner diameter, the department

Wall thickness: The second parameter wall thickness refers to the pipe wall of the thin, the inner diameter shows the size of the pipe, what is a wall thickness refers to? Macroscopic is the thickness of the goods, we know that the role of heat shrinkable pipe is insulation protection, so thick and thin reaction is the size of insulation protection, we all know that the thickness of heat, so the role of cold heating is large, the power of the heat shrinkable tube is small, because the wall thickness of the hot shrinkage pipe is its protective power, analysis, The thicker the heat shrinkable tube, the better the protective power of the machine.

Expansion rate: Heat shrinkable tube Heating will expand, and as long as the expansion will have a certain parameter, the expansion rate is also known as heat shrinkage, heat shrinkage ratio and so on, it refers to the heat shrinkable tube at room temperature, such as φ6, is heating after the diameter of the shrinkage, such as φ3, So what we call the expansion rate is the ratio of the inner diameter of the heat shrinkable tube before expansion to the inner diameter of the expansion, that is to say, 6/3=2/1, a certain 2:1 is the expansion rate of the casing, the expansion rate shows the size of the expansion power of the heat shrinkable casing If the heat shrinkable tube expands before the φ6, the expansion is φ2, as long as two millimeters of the size, then its expansion rate is 6:2, that is, 3:1.

热缩套管参数分析

热缩管在通路中并不是主要机件，但在通路中却肩负着掩护通路与主要机件的作用。只要依据适合的分寸取舍热缩管，能力最大水平上完成对于通路的掩护。本篇作品当中，小编将为大家引见热缩管的那些根底参数。

内径:大家知道套管的横截面是圆柱管状，内径就是管壁内直径的大小，即内壁之间的间隔大小，咱们一般用Φ来标识，由于Φ正在工事上都是用于标点直径的，而后前面跟上数字，标明内径的值，部门默许没有写的话都是MM毫米，比方说Φ6。

壁厚:第二个参数壁厚指的是管壁的薄厚，内径表现的是管子的大小，某个壁厚指的是什么呢？宏观的来讲就是货物的厚薄，大家知道热缩管起到的作用是绝缘防护，那样厚薄反应的就是绝缘防护的大小，咱们都晓得上装厚了，那样防寒供暖的作用就大，上装薄了御寒的威力就小，因为热缩管的壁厚反应的就是它的防护威力，分析来说，越厚的热缩管其机器防护威力越好。

膨胀率:热缩管加热会膨胀，而只要膨胀的才会有某个参数，膨胀率也就是所谓的热缩率，热缩比重之类，它指的是热缩管正在常温下的直径比方说Φ6，正在加热缩完后的直径比方说Φ3，那样咱们所说的膨胀率就是热缩管正在膨胀前的内径与膨胀后内径的比率，也就是说6/3=2/1，某个2:1就是套管的膨胀率，膨胀率表现的是热缩套管膨胀威力的大小，膨胀率越高，热缩套管彻底膨胀后越细。假如说热缩管膨胀前是Φ6，膨胀后是Φ2，只要两个毫米的大小，那样它的膨胀率就是6:2，也就是3:1。
