The main performance of the heat shrinkable tube is that it shrinks after heating, and with this particular condition, it is determined that the heat shrinkable tube can fit well with the items that need to shrink, so as to better realize its protection function. But some items with complex shapes, if you want to make the heat shrinkable tube shrink perfectly fit the item, there is a bit of trouble, need some skills and experience.

When the heat shrinkable tube is heated and shrunk on the threaded object, the different shrinkage state is presented, how to shrink the heat shrinkable tube on the stainless steel corrugated hose, so that the heat shrinkable tube is more attuned to the bellows after shrinkage, the surface is smooth and also shows obvious corrugated shape.

After a long period of repeated experiments in our company, summed up some experience to share with you, I hope to be able to use the heat shrinkable tube in the process of help, specifically the following four points:

1. Heat shrinkable pipe wall thickness to be thin

If the wall thickness is too thick, it is difficult to highlight the shape of the shrunk object after a complete contraction, and it is difficult to achieve uniform heat during heating and shrinkage. It is best to choose thin-walled heat shrinkable tube, do not use thick wall heat shrinkage tube.

2. The shrinkage of the heat shrinkable tube should be greater than three times times the best

Corrugated pipe thread is deep, select a large magnification of the heat shrinkable tube to ensure that the complete heat shrinkage after the convex sense is stronger, so as to achieve a high degree of fit between the heat shrinkable tube and the corrugated pipe.

3. It is best to use the heat shrinkage specifications smaller

When selecting specifications, we usually select the diameter of the heat shrinkable tube after shrinkage, which is smaller than that of the quilt object. Here the diameter of the quilt object values the diameter of the corrugated tube sag part.

4. Apply some silicone oil lubricant to the corrugated pipe during shrinkage

When shrinking, apply silicone oil lubricant, which can better remove air when heating, so that the heat shrinkable tube is more attuned to the bellows.

When the heat shrinkable tube heats and shrinks, it begins to shrink gradually from one end to the other, preferably blocking the flame with a ring bezel at the same time, moving at the edge of the block to ensure that it is evenly heated. The purpose of this is also to exhaust, so that the heat shrinkable tube shrinkage, more compatible with the corrugated pipe.

怎样才能让热缩管完美包裹波纹管

热缩管的最主要性能就是加热后会收缩的，有了这一特定条件决定了热缩管能很好的贴合需要收缩的物品，从而更好的实现其防护功能。但有些形状复杂的物品，若想使热缩管收缩后完美贴合物品，就有一点麻烦，需要一些技巧和经验。

热缩管在螺纹物件上被加热收缩之后所呈现出来的不同收缩状态，那如何在不锈钢波纹软管上收缩热缩管，使其收缩后热缩管更加贴合波纹管，表面光滑同时也呈现明显的波纹形状。

经过我们公司长期反复实验，总结出一些经验分享给您，希望能在使用热缩管的过程中有所帮助，具体有以下四点：

1. 热缩管壁厚要薄

如果壁厚太厚，完全收缩之后也难以突显出被收缩物体的本身形态，且在加热收缩的过程中也很难达到均匀受热。最好选用薄壁热缩管，不要用厚壁热缩管。

2. 热缩管的收缩倍数要大最好三倍以上

波纹管螺纹较深，选择大倍率的热缩管才能保证完全热缩之后凹凸感更强烈，从而达到热缩管与波纹管的高度契合。

3. 最好选用热缩的规格偏小些

在选择规格的时候，我们通常会挑选热缩管收缩之后，内径小于被套物体的直径。这里被套物体的直径取值波纹管凹陷部分的直径。

4. 收缩时波纹管上涂抹些硅油类的润滑剂

收缩时涂抹硅油类润滑剂，能够在加热时更好的排除空气，使热缩管更贴合波纹管。

热缩管加热收缩的时候，从一端开始逐渐收缩到另一端，最好同时用环形挡板挡住火焰，边挡边移动，确保其均匀受热。这样做的目的也是为了排气，使热缩管收缩后，更契合波纹管。
