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.
