Double-walled tube is a soft, flame-retardant, irradiated cross-linked double-walled hot shrinkage casing, the inner layer has a good adhesion performance of hot melt adhesive, outer layer for radiation crosslinked polyolefin materials, shrinkage after the hot melt adhesive can be connected to the two ends of the material completely sealed, easy to work, no maintenance, resistance to harsh environment, moisture and other impact, Used in cable connection, cable and component sealing moisture-proof, waterproof, anti-corrosion and insulation protection, repair of damaged cable insulating layer and so on. If the daily storage of double-walled tubes is not usually done, it will greatly affect the effect of double-walled tubes, next I will be about the storage of double-walled tubes under the introduction.

How to store for two-walled tubes, mainly divided into the following three aspects:

1, heat shrinkage double-walled tube need to be stored in the ventilation, drying, heat shrinkable pipe clean warehouse, to avoid contact with light, heat source and other radiation. At the same time, it is necessary to avoid rain, heavy pressure and a variety of external force impact. For warehouses that store hot-shrinkable double-walled tubes, the temperature is preferably not more than 30 ℃, and the humidity should not exceed 55%.

2, heat shrinkage double-walled tube has flammability, so should avoid with flammable and explosive items with inventory. For long-stored heat-shrinkable double-walled tube products, if there is a warehouse order, should give priority to the inventory of products for a long time. For the use of the remaining heat shrinkable double-walled tube products, need to clean the material packaging, to prevent dust and other adsorption on the top.

3, heat shrinkage double-walled tube as far as possible do not store too long, which will lead to poor memory viscosity, performance on the discount, so the recent on-demand purchase, on demand, to ensure the stability of quality.

Double wall heat shrinkable pipe above is my simple introduction for how to store double-walled tubes, I hope that through our introduction can bring you help, a lot of types of double-walled tubes, so the storage of all kinds of products is also different, should do targeted treatment, rather than all in one way, so it will be counterproductive.

Double-walled tubes are widely used in daily life, for people to bring a lot of convenience, but in the daily installation process often there are some problems, to solve these problems, we need to understand the main points of its installation, and then let me give you a answer, I hope it will be helpful to you.

Double-walled tube structure unique, high strength, easy installation, fast construction, environmental protection, the following I would like to introduce you to its installation precautions.

High temperature heat shrinkable pipe installation considerations for double-walled tubes:

1, to be used double-walled pipe should be in accordance with product standards for each quality inspection, do not meet the standards should not be used, and should be marked, separate treatment;

2, double-walled pipe site should be manual handling, handling should be lightly carried lightly;

3, before the next tube, where the pipe deformation test should be carried out section of the tube, should be in advance to measure the actual diameter of the section pipe, and make a mark;

4, manual under the tube, by the ground personnel will be the pipe to the groove construction personnel, the slope excavation of the groove can also be used non-metallic ropes to tie the two ends of the tube body, to keep the balance of the pipe body evenly slipped into the groove, it is strictly prohibited to roll the pipe from the top edge of the groove into the groove;

5, Crane under the hoisting, the application of non-metallic rope buckle tied, not a series of heart hoisting.

热缩双壁管的储藏方式及壁管的安装要点

双壁管是一种柔软、阻燃、辐照交联双壁含胶热收缩套管，内层系具有良好粘接性能的热熔胶，外层为辐射交联聚烯烃材料，收缩后热熔胶能将连接两端的材料完全密封，易施工、不需保养，能耐恶劣环境、湿气等冲击，达到保护零组件作用，应用于线缆接续、线缆和元器件的密封防潮、防水、防蚀和绝缘保护，修复受损的线缆绝缘层等。如果平时不做好双壁管的日常存储，就会大大影响双壁管的效果，接下来我会关于双壁管的存储作下介绍。

如何针对双壁管进行存储呢，主要分为以下三个个方面：

1、热缩双壁管需要储存于通风、干燥、热缩管洁净的库房中，需避免接触光照、热源等辐射。同时还需避免雨淋、重压及各种外力冲击。对于储存热缩双壁管的仓库，其温度最好不超过30℃，湿度应不超过55%。

2、热缩双壁管具有燃烧性，所以应避免与易燃易爆物品同库存放。对于存放时间较久的热缩双壁管产品，若有出库订单时，应优先出库存放时间久的产品。对于用剩的热缩双壁管产品，需用干净的材料包装好，防止灰尘等吸附在上面。

3、热缩双壁管尽量不要存放时间过长，这样会导致内存黏性变差，性能对打折扣，所以最近按需购买，按需使用，保证质量的稳定。

双壁热缩管以上就是我为大家针对如何存储双壁管做的简单介绍，希望通过我们的介绍能给大家带来帮助，双壁管的种类很多，所以各类产品的存储也是有区别的，应做针对性处理，而不是所有都按一种方式，这样反而会起到反作用。

双壁管在日常生活中使用广泛，为人们带来很多的便利，但是在日常安装过程中经常会出现一些问题，想要解决这些问题，就需要我们了解它安装时的要点，接下来让我会为大家作一一解答，希望能对你们有所帮助。

双壁管结构独特、强度高、安装方便、施工快捷、环保，下面我为大家介绍其安装注意事项。

双壁管的高温热缩管安装注意事项：

1、待用的双壁管应按产品标准每个进行质量检验，不符合标准不得使用，并应做好记号，另行处理;

2、双壁管现场应由人工搬运，搬运时应轻抬轻放;

3、下管前，凡规定须进行管道变形检测的断面的管材，应预先量出该断面管道的实际直径，并做出记号;

4、人工下管时，由地面人员将管材传递给沟槽内施工人员;对放坡开挖的沟槽也可用非金属绳索系住管身两端，保持管身平衡均匀溜放至沟槽内，严禁将管材由槽顶边滚入槽内;

5、起重机下管吊装时，应用非金属绳索扣系住，不得串心吊装。
